We do not support intra-cluster connections on multiple interfaces, but the
documentation indicates that we will in future. In fact there is currently no
plan to support this, so the forward-looking documentation is misleading. This
commit
- removes the misleading sentence
- fixes that a transport profile affects outbound connections, not inbound ones
- tidies up some nearby text
Relates #29827
This implementation behaves like the current transport client, that you basically cannot configure a Watch POJO representation as an argument to the put watch API, but only a bytes reference. You can use the the `WatchSourceBuilder` from the `org.elasticsearch.plugin:x-pack-core` dependency to build watches.
This commit also changes the license type to trial, so that watcher is available in high level rest client tests.

Today it is unclear what guarantees are offered by the search preference
feature, and we claim a guarantee that is stronger than what we really offer:
> A custom value will be used to guarantee that the same shards will be used
> for the same custom value.
This commit clarifies this documentation.
Forward-port of #32098 to `master`.
This change adds two contexts the execute scripts against:
* SEARCH_SCRIPT: Allows to run scripts in a search script context.
This context is used in `function_score` query's script function,
script fields, script sorting and `terms_set` query.
* FILTER_SCRIPT: Allows to run scripts in a filter script context.
This context is used in the `script` query.
In both contexts a index name needs to be specified and a sample document.
The document is needed to create an in-memory index that the script can
access via the `doc[...]` and other notations. The index name is needed
because a mapping is needed to index the document.
Examples:
```
POST /_scripts/painless/_execute
{
"script": {
"source": "doc['field'].value.length()"
},
"context" : {
"search_script": {
"document": {
"field": "four"
},
"index": "my-index"
}
}
}
```
Returns:
```
{
"result": 4
}
```
POST /_scripts/painless/_execute
{
"script": {
"source": "doc['field'].value.length() <= params.max_length",
"params": {
"max_length": 4
}
},
"context" : {
"filter_script": {
"document": {
"field": "four"
},
"index": "my-index"
}
}
}
Returns:
```
{
"result": true
}
```
Also changed PainlessExecuteAction.TransportAction to use TransportSingleShardAction
instead of HandledAction, because now in case score or filter contexts are used
the request needs to be redirected to a node that has an active IndexService
for the index being referenced (a node with a shard copy for that index).
The current docs of the put-mapping Java API is currently broken. It its current
form, it creates an index and uses the whole mapping definition given as a JSON
string as the type name. Since we didn't check the index created in the
IndicesDocumentationIT so far this went unnoticed.
This change adds test to catch this error to the documentation test, changes the
documentation so it works correctly now and adds an input validation to
PutMappingRequest#buildFromSimplifiedDef() which was used internally to reject
calls where no mapping definition is given.
Closes#31906
Currently the `keep_types` token filter includes all token types specified using
its `types` parameter. Lucenes TypeTokenFilter also provides a second mode where
instead of keeping the specified tokens (include) they are filtered out
(exclude). This change exposes this option as a new `mode` parameter that can
either take the values `include` (the default, if not specified) or `exclude`.

* Adds a new auto-interval date histogram
This change adds a new type of histogram aggregation called `auto_date_histogram` where you can specify the target number of buckets you require and it will find an appropriate interval for the returned buckets. The aggregation works by first collecting documents in buckets at second interval, when it has created more than the target number of buckets it merges these buckets into minute interval bucket and continues collecting until it reaches the target number of buckets again. It will keep merging buckets when it exceeds the target until either collection is finished or the highest interval (currently years) is reached. A similar process happens at reduce time.
This aggregation intentionally does not support min_doc_count, offest and extended_bounds to keep the already complex logic from becoming more complex. The aggregation accepts sub-aggregations but will always operate in `breadth_first` mode deferring the computation of sub-aggregations until the final buckets from the shard are known. min_doc_count is effectively hard-coded to zero meaning that we will insert empty buckets where necessary.
Closes#9572

* iterates on tests
* Adds test case and documentation changes
Added some notes in the documentation about the intervals that can bbe

Also added a test case that utilises the merging of conseecutive buckets
* Fixes performance bug
The bug meant that getAppropriate rounding look a huge amount of time
if the range of the data was large but also sparsely populated. In
these situations the rounding would be very low so iterating through
the rounding values from the min key to the max keey look a long time
(~120 seconds in one test).
The solution is to add a rough estimate first which chooses the
rounding based just on the long values of the min and max keeys alone
but selects the rounding one lower than the one it thinks is
appropriate so the accurate method can choose the final rounding taking
into account the fact that intervals are not always fixed length.

This commit adds the _xpack/usage api to the high level rest client.
Currently in the transport api, the usage data is exposed in a limited
fashion, at most giving one level of helper methods for the inner keys
of data, but then exposing thos subobjects as maps of objects. Rather
than making parsers for every set of usage data from each feature, this
PR exposes the entire set of usage data as a map of maps.
Because this is a static method on a public API, and one that we encourage
plugin authors to use, the method with the typo is deprecated in 6.x
rather than just renamed.
With this commit we introduce a new circuit-breaking strategy to the parent
circuit breaker. Contrary to the current implementation which only accounts for
memory reserved via child circuit breakers, the new strategy measures real heap
memory usage at the time of reservation. This allows us to be much more
aggressive with the circuit breaker limit so we bump it to 95% by default. The
new strategy is turned on by default and can be controlled with the new cluster
setting `indices.breaker.total.userealmemory`.
Note that we turn it off for all integration tests with an internal test cluster
because it leads to spurious test failures which are of no value (we cannot
fully control heap memory usage in tests). All REST tests, however, will make
use of the real memory circuit breaker.

(cherry picked from commit d2e5db8a806ec8a25162f79db5209aceed4f30f7)
This is the first x-pack API we're adding to the high level REST client
so there is a lot to talk about here!
= Open source
The *client* for these APIs is open source. We're taking the previously
Elastic licensed files used for the `Request` and `Response` objects and
relicensing them under the Apache 2 license.
The implementation of these features is staying under the Elastic
license. This lines up with how the rest of the Elasticsearch language
clients work.
= Location of the new files
We're moving all of the `Request` and `Response` objects that we're
relicensing to the `x-pack/protocol` directory. We're adding a copy of
the Apache 2 license to the root fo the `x-pack/protocol` directory to
line up with the language in the root `LICENSE.txt` file. All files in
this directory will have the Apache 2 license header as well. We don't
want there to be any confusion. Even though the files are under the
`x-pack` directory, they are Apache 2 licensed.
We chose this particular directory layout because it keeps the X-Pack
stuff together and easier to think about.
= Location of the API in the REST client
We've been following the layout of the rest-api-spec files for other
APIs and we plan to do this for the X-Pack APIs with one exception:
we're dropping the `xpack` from the name of most of the APIs. So
`xpack.graph.explore` will become `graph().explore()` and
`xpack.license.get` will become `license().get()`.
`xpack.info` and `xpack.usage` are special here though because they
don't belong to any proper category. For now I'm just calling
`xpack.info` `xPackInfo()` and intend to call usage `xPackUsage` though
I'm not convinced that this is the final name for them. But it does get
us started.
= Jars, jars everywhere!
This change makes the `xpack:protocol` project a `compile` scoped
dependency of the `x-pack:plugin:core` and `client:rest-high-level`
projects. I intend to keep it a compile scoped dependency of
`x-pack:plugin:core` but I intend to bundle the contents of the protocol
jar into the `client:rest-high-level` jar in a follow up. This change
has grown large enough at this point.
In that followup I'll address javadoc issues as well.
= Breaking-Java
This breaks that transport client by a few classes around. We've
traditionally been ok with doing this to the transport client.

Relates to #31797
This is a followup to #31537. It makes a number of changes requested by
a review that came after the PR was merged. These are mostly cleanups
and doc improvements.
Only the shards that receive the bulk request will be affected by
`refresh`. Imagine a `_bulk?refresh=wait_for` request with three
documents in it that happen to be routed to different shards in an index
with five shards. The request will only wait for those three shards to
refresh. The other two shards of that make up the index do not
participate in the `_bulk` request at all.

SQL: Update CLI logo
Removes support for storing scripts without the usual json around the
script. So You can no longer do:
```
POST _scripts/<templatename>
{
"query": {
"match": {
"title": "{{query_string}}"
}
}
}
```
and must instead do:
```
POST _scripts/<templatename>
{
"script": {
"lang": "mustache",
"source": {
"query": {
"match": {
"title": "{{query_string}}"
}
}
}
}
}
```
This improves error reporting when you attempt to store a script but don't
quite get the syntax right. Before, there was a good chance that we'd
think of it as a "raw" template and just store it. Now we won't do that.
Nice.

ingest: Introduction of a bytes processor
This processor allows for human readable byte values (e.g. 1kb) to be converted to value in bytes (e.g. 1024). Internally this processor re-uses "ByteSizeValue.parseBytesSizeValue" which supports conversions up to Long.MAX_VALUE and the following units: "b", "kb", "mb", "gb", "tb", pb".
This change also introduces a generic return type for the AbstractStringProcessor to allow for code reuse while supporting a String -> T conversion. (String -> Long in this case).
Significantly improve the example snippets in the documentation.
The examples are part of the test suite and checked nightly.
To help readability, the existing dataset was extended (test_emp renamed
to emp plus library).
Improve output of JDBC tests to be consistent with the CLI
Add lenient flag to JDBC asserts to allow type widening (a long is
equivalent to a integer as long as the value is the same).
AWS supports the creation and use of credentials that are only valid for a
fixed period of time. These credentials comprise three parts: the usual access
key and secret key, together with a session token. This commit adds support for
these three-part credentials to the EC2 discovery plugin and the S3 repository
plugin.
Note that session tokens are only valid for a limited period of time and yet
there is no mechanism for refreshing or rotating them when they expire without
restarting Elasticsearch. Nonetheless, this feature is already useful for
nodes that need only run for a few days, such as for training, testing or
evaluation. #29135 tracks the work towards allowing these credentials to be
refreshed at runtime.
Resolves#16428
So far the in-flight request circuit breaker has only accounted for the
on-the-wire representation of a request. However, we convert the raw
request into XContent internally which increases the overhead.
Therefore, we increase the value of the corresponding setting
`network.breaker.inflight_requests.overhead` from one to two. While this
value is still rather conservative (we assume that the representation as
structured objects has no overhead compared to the byte[]), it is closer
to reality than the current value.

[TEST] call yaml client close method from test suite (#31591)
The range docs had an introductory section that described how to set up

duplicated that section. This is bad because these section can (and do)
drift from one another. This change removes the setup in build.gradle
and marks the introductor snippet with `// TESTSETUP` so it is used on
all the snippets.
Skips tests the require xpack if we run the doc build without xpack. So
this should work:
```
./gradlew -p docs check -Dtests.distribution=oss-zip
```
This is implemented by detecting parts of the doc that look like:
```
[testenv="basic"]
```

We have made node selectors configurable per request, but all
of other language clients don't allow for that.
A good reason not to do so, is that having a different node selector
per request breaks round-robin. This commit makes NodeSelector
configurable only at client initialization. It also improves the docs
on this matter, important given that a single node selector can still
affect round-robin.
Since #31251, we use the default distribution to test docs. With this
distribution, the cat thread-pool response will include the ccr
thread-pool. This commit adjusts /_cat/thread_pool doc to include ccr.

A link to the ip_range datatype page provides a way for newer users to know
it exists if they land directly on the ip datatype page first via a search.
The `multiplexer` filter emits multiple tokens at the same position, each
version of the token haivng been passed through a different filter chain.
Identical tokens at the same position are removed.
This allows users to, for example, index lowercase and original-case tokens,
or stemmed and unstemmed versions, in the same field, so that they can search
for a stemmed term within x positions of an unstemmed term.
Folks tend to want to be able to make a single `_reindex` call to
migrate many indices. You *can* do that and we even have an example of
how to do that in the docs but it isn't always a good idea. This change
adds some advice to the docs: generally you want to make one reindex
call per index.
Closes#22920
In 6.3 this was moved to `Strings.toString(XContentBuilder)` as part of the

Resolves#31326
This switches the docs tests from the `oss-zip` distribution to the
`zip` distribution so they have xpack installed and configured with the
default basic license. The goal is to be able to merge the
`x-pack/docs` directory into the `docs` directory, marking the x-pack
docs with some kind of marker. This is the first step in that process.
This also enables `-Dtests.distribution` support for the `docs`
directory so you can run the tests against the `oss-zip` distribution
with something like
```
./gradlew -p docs check -Dtests.distribution=oss-zip
```
We can set up Jenkins to run both.
Relates to #30665
The other metric aggregations (min/max/etc) return `null` as their XContent value and string when nothing was computed (due to empty/missing fields). Percentiles and Percentile Ranks, however, return `NaN `which is inconsistent and confusing for the user. This fixes the inconsistency by making the aggs return `null`. This applies to both the numeric value and the "as string" value.
Note: like the metric aggs, this does not change the value if fetched directly from the percentiles object, which will return as `NaN`/`"NaN"`. This only changes the XContent output.
While this is a bugfix, it still breaks bwc in a minor way as the response changes from prior version.
Closes#29066
This commit adds the is-write-index flag for aliases.
It allows requests to set the flag, and responses to display the flag.
It does not validate and/or affect any indexing/getting/updating behavior
of Elasticsearch -- this will be done in a follow-up PR.
Add a `NodeSelector` so that users can filter the nodes that receive
requests based on node attributes.
I believe we'll need this to backport #30523 and we want it anyway.
I also added a bash script to help with rebuilding the sniffer parsing
test documents.
With #29331 we added support for the cluster health API to the
high-level REST client. The transport client does not support the level
parameter, and it always returns all the info needed for shards level
rendering. We have maintained that behaviour when adding support for
cluster health to the high-level REST client, to ease migration, but the
correct thing to do is to default the high-level REST client to
`cluster` level, which is the same default as when going through the
Elasticsearch REST layer.
This commit removes all the API methods that accept a `Header` varargs
argument, in favour of the newly introduced API methods that accept a
`RequestOptions` argument.

Given the weirdness of the response returned by the get alias API, we went for a client specific response, which allows us to hold the error message, exception and status returned as part of the response together with aliases. See #30536 .

This adds a thread interrupter that allows us to encapsulate calls to org.joni.Matcher#search()
This method can hang forever if the regex expression is too complex.
The thread interrupter in the background checks every 3 seconds whether there are threads
execution the org.joni.Matcher#search() method for longer than 5 seconds and
if so interrupts these threads.
Joni has checks that that for every 30k iterations it checks if the current thread is interrupted and
if so returns org.joni.Matcher#INTERRUPTED
Closes#28731
Allows users of the Low Level REST client to specify which hosts a
request should be run on. They implement the `NodeSelector` interface
or reuse a built in selector like `NOT_MASTER_ONLY` to chose which nodes
are valid. Using it looks like:
```
Request request = new Request("POST", "/foo/_search");
RequestOptions options = request.getOptions().toBuilder();
options.setNodeSelector(NodeSelector.NOT_MASTER_ONLY);
request.setOptions(options);
...
```
This introduces a new `Node` object which contains a `HttpHost` and the
metadata about the host. At this point that metadata is just `version`
and `roles` but I plan to add node attributes in a followup. The
canonical way to **get** this metadata is to use the `Sniffer` to pull
the information from the Elasticsearch cluster.
I've marked this as "breaking-java" because it breaks custom
implementations of `HostsSniffer` by renaming the interface to
`NodesSniffer` and by changing it from returning a `List<HttpHost>` to a
`List<Node>`. It *shouldn't* break anyone else though.
Because we expect to find it useful, this also implements `host_selector`
support to `do` statements in the yaml tests. Using it looks a little
like:
```
---
"example test":
- skip:
features: host_selector
- do:
host_selector:
version: " - 7.0.0" # same syntax as skip
apiname:
something: true
```
The `do` section parses the `version` string into a host selector that
uses the same version comparison logic as the `skip` section. When the
`do` section is executed it passed the off to the `RestClient`, using
the `ElasticsearchHostsSniffer` to sniff the required metadata.
The idea is to use this in mixed version tests to target a specific
version of Elasticsearch so we can be sure about the deprecation
logging though we don't currently have any examples that need it. We do,
however, have at least one open pull request that requires something
like this to properly test it.
Closes#21888
With `max_concurrent_shard_requests` we used to throttle / limit
the number of concurrent shard requests a high level search request
can execute per node. This had several problems since it limited the
number on a global level based on the number of nodes. This change
now throttles the number of concurrent requests per node while still
allowing concurrency across multiple nodes.

This commit reworks testing for `ListTasksResponse` so that random

This field is similar to the `feature` field but is better suited to index
sparse feature vectors. A use-case for this field could be to record topics
associated with every documents alongside a metric that quantifies how well
the topic is connected to this document, and then boost queries based on the
topics that the logged user is interested in.

By default span_multi query will limit term expansions = boolean max clause.
This will limit high heap usage in case of high cardinality term
expansions. This applies only if top_terms_N is not used in inner multi
query.
* Fix index prefixes to work with span_multi
Text fields that use `index_prefixes` can rewrite `prefix` queries into
`term` queries internally. This commit fix the handling of this rewriting
in the `span_multi` query.
This change also copies the index options of the text field into the
prefix field in order to be able to run positional queries. This is mandatory
for `span_multi` to work but this could also be useful to optimize `match_phrase_prefix`
queries in a follow up. Note that this change can only be done on indices created
after 6.3 since we set the index options to doc only in this version.

* Update wording following review
Specifying `index_phrases: true` on a text field mapping will add a subsidiary
[field]._index_phrase field, indexing two-term shingles from the parent field.
The parent analysis chain is re-used, wrapped with a FixedShingleFilter.
At query time, if a phrase match query is executed, the mapping will redirect it
to run against the subsidiary field.
This should trade faster phrase querying for a larger index and longer indexing
times.

This change adds an option named `split_queries_on_whitespace` to the `keyword`

Closes#30393
This change deprecates completion queries and documents without context that target a

will be removed in 7 in a follow up.

Currently failures to compile a script usually lead to a ScriptException, which
inherits the 500 INTERNAL_SERVER_ERROR from ElasticsearchException if it does
not contain another root cause. Instead, this should be a 400 Bad Request error.
This PR changes this more generally for script compilation errors by changing
ScriptException to return 400 (bad request) as status code.
Closes#12315
This change adds a new option to the composite aggregation named `missing_bucket`.
This option can be set by source and dictates whether documents without a value for the
source should be ignored. When set to true, documents without a value for a field emits
an explicit `null` value which is then added in the composite bucket.
The `missing` option that allows to set an explicit value (instead of `null`) is deprecated in this change and will be removed in a follow up (only in 7.x).
This commit also changes how the big arrays are allocated, instead of reserving
the provided `size` for all sources they are created with a small intial size and they grow
depending on the number of buckets created by the aggregation:

This reverts commit 31251c9 introduced in #30695.
We suspect this commit is causing the OOME's reported in #30811 and we will use this PR to test this assertion.
This commit adds the ability to configure how a docvalue field should be
formatted, so that it would be possible eg. to return a date field
formatted as the number of milliseconds since Epoch.

Lucene has a new `FeatureField` which gives the ability to record numeric
features as term frequencies. Its main benefit is that it allows to boost
queries with the values of these features and efficiently skip non-competitive
documents at the same time using block-max WAND and indexed impacts.
Adding headers rather than setting them all at once seems more
user-friendly and we already do it in a similar way for parameters
(see Request#addParameter).
Currently the first snippet in the documentation test in script-fields.asciidoc
isn't executed, although it has the CONSOLE annotation. Adding a test setup
annotation to it seems to fix the problem.
This is related to #29500 and #28898. This commit removes the abilitiy
to disable http pipelining. After this commit, any elasticsearch node
will support pipelined requests from a client. Additionally, it extracts
some of the http pipelining work to the server module. This extracted
work is used to implement pipelining for the nio plugin.
=== Char Group Tokenizer
The `char_group` tokenizer breaks text into terms whenever it encounters
a
character which is in a defined set. It is mostly useful for cases where
a simple
custom tokenization is desired, and the overhead of use of the
<<analysis-pattern-tokenizer, `pattern` tokenizer>>
is not acceptable.
=== Configuration
The `char_group` tokenizer accepts one parameter:
`tokenize_on_chars`::
A string containing a list of characters to tokenize the string on.
Whenever a character
from this list is encountered, a new token is started. Also supports
escaped values like `\\n` and `\\f`,
and in addition `\\s` to represent whitespace, `\\d` to represent
digits and `\\w` to represent letters.
Defaults to an empty list.
=== Example output
```The 2 QUICK Brown-Foxes jumped over the lazy dog's bone for $2```
When the configuration `\\s-:<>` is used for `tokenize_on_chars`, the
above sentence would produce the following terms:
```[ The, 2, QUICK, Brown, Foxes, jumped, over, the, lazy, dog's, bone,
for, $2 ]```

The getDate() and getDates() existed prior to 5.x on long fields in
scripting. In 5.x, a new Date type for ScriptDocValues was added. The
getDate() and getDates() methods were left on long fields and added to date
fields to ease the transition. This commit removes those methods for
7.0.
The docs/README shows how to run the :docs:check goal on a subset of pages,
however using the current example fails. Removing the masking character before
the first wildcard fixes the problem.
Meta plugins existed only for a short time, in order to enable breaking
up x-pack into multiple plugins. However, now that x-pack is no longer
installed as a plugin, the need for them has disappeared. This commit
removes the meta plugins infrastructure.
This pipeline aggregation gives the user the ability to script functions that "move" across a window
of data, instead of single data points. It is the scripted version of MovingAvg pipeline agg.

- MovingFunctions.min()
- MovingFunctions.sum()
- MovingFunctions.unweightedAvg()
- MovingFunctions.linearWeightedAvg()
- MovingFunctions.ewma()
- MovingFunctions.holt()
- MovingFunctions.holtWinters()
- MovingFunctions.stdDev()
The user can also define any arbitrary logic via their own scripting, or combine with the above methods.

Closes#29196
This commit changes the default out-of-the-box configuration for the
number of shards from five to one. We think this will help address a
common problem of oversharding. For users with time-based indices that
need a different default, this can be managed with index templates. For
users with non-time-based indices that find they need to re-shard with
the split API in place they no longer need to resort only to
reindexing.
Since this has the impact of changing the default number of shards used
in REST tests, we want to ensure that we still have coverage for issues
that could arise from multiple shards. As such, we randomize (rarely)
the default number of shards in REST tests to two. This is managed via a
global index template. However, some tests check the templates that are
in the cluster state during the test. Since this template is randomly
there, we need a way for tests to skip adding the template used to set
the number of shards to two. For this we add the default_shards feature
skip. To avoid having to write our docs in a complicated way because
sometimes they might be behind one shard, and sometimes they might be
behind two shards we apply the default_shards feature skip to all docs
tests. That is, these tests will always run with the default number of
shards (one).
The High Level REST Client's documentation suggested that users should
use the Low Level REST Client for index management activities. This
change removes that suggestion because the high level REST client
supports those APIs now.
This also changes the examples in the migration docs to that still use
the Low Level REST Client to use the non-deprecated varieats of
`performRequest`.
We want copying settings to be the default behavior. This commit
deprecates not copying settings, and disallows explicitly not copying
settings. This gives users a transition path to the future default
behavior.
Dates internally contain milliseconds (which appear when converting them
to Strings) however parsing does not accept them (and is being strict).
The parser has been changed so that Date is mandatory but the time
(including its fractions such as millis) are optional.
Fix#30002
We have a pile of documentation describing how to rebuild the built in
language analyzers and, previously, our documentation testing framework
made sure that the examples successfully built *an* analyzer but they
didn't assert that the analyzer built by the documentation matches the
built in anlayzer. Unsuprisingly, some of the examples aren't quite
right.
This adds a mechanism that tests that the analyzers built by the docs.
The mechanism is fairly simple and brutal but it seems to be working:
build a hundred random unicode sequences and send them through the
`_analyze` API with the rebuilt analyzer and then again through the
built in analyzer. Then make sure both APIs return the same results.
Each of these calls to `_anlayze` takes about 20ms on my laptop which
seems fine.
This commit adds the Snapshot Client with a first API call within it,

Today we can execute cluster API actions on only master, data or ingest nodes
using the `master:true`, `data:true` and `ingest:true` filters, but it is not
so easy to select coordinating-only nodes (i.e. those nodes that are neither
master nor data nor ingest nodes). This change fixes this by adding support for
a `coordinating_only` filter such that `coordinating_only:true` adds all
coordinating-only nodes to the set of selected nodes, and
`coordinating_only:false` deletes them.
Resolves#28831.
The HTTPClient used in watcher is based on the apache http client. The
current client is using a lot of defaults - which are not always
optimal. Two of those defaults are the maximum number of total
connections and the maximum number of connections to a single route.
If one of those limits is reached, the HTTPClient waits for a connection
to be finished thus acting in a blocking fashion. In order to prevent
this when many requests are being executed, we increase the limit of
total connections as well as the connections per route (a route is
basically an endpoint, which also contains proxy information, not
containing an URL, just hosts).
On top of that an additional option has been set to evict
long running connections, which can potentially be reused after some
time. As this requires an additional background thread, this required
some changes to ensure that the httpclient is closed properly. Also the
timeout for this can be configured.
Deprecate the many arguments versions of `performRequest` and
`performRequestAsync` in favor of the `Request` object flavored variants
introduced in #29623. We'll be dropping the many arguments variants in
7.0 because they make it difficult to add new features in a backwards
compatible way and they create a *ton* of intellisense noise.
We had been using `task_id:1` or `taskId:1` because it is parses as a
valid task identifier but the `:1` part is confusing. This replaces
those examples with `task_id` which matches the response from the list
tasks API.

When deleting or creating a snapshot for a given shard, elasticsearch
usually starts by listing all the existing snapshotted files in the repository.
Then it computes a diff and deletes the snapshotted files that are not
needed anymore. During this deletion, an exception is thrown if the file
to be deleted does not exist anymore.
This behavior is challenging with cloud based repository implementations
like S3 where a file that has been deleted can still appear in the bucket for
few seconds/minutes (because the deletion can take some time to be fully
replicated on S3). If the deleted file appears in the listing of files, then the
following deletion will fail with a NoSuchFileException and the snapshot
will be partially created/deleted.
This pull request makes the deletion of these files a bit less strict, ie not
failing if the file we want to delete does not exist anymore. It introduces a
new BlobContainer.deleteIgnoringIfNotExists() method that can be used
at some specific places where not failing when deleting a file is
considered harmless.
Closes#28322
Today when processing a request for a URL path for which we can not find
a handler we send back a plain-text response. Yet, we have the accept
header in our hand and can respect the accepted media type of the
request. This commit addresses this.
This change adds a new plugin called `analysis-nori` that exposes
Korean text analysis in es using the new Lucene Korean analyzer module named (`nori`).
The plugin adds:
* a Korean analyzer: `nori`
* a Korean tokenizer: `nori_tokenizer`
* a part of speech stop filter: `nori_part_of_speech`
* a filter that can replace Hanja characters with their Hangul transcription: `nori_readingform`
When validating the search request, we make sure any date_histogram
aggregations have timezones that match the jobs. But we didn't
do any such validation on range queries.
While it wouldn't produce incorrect results, it would be confusing
to the user as no documents would match the aggregation (because we
add a filter clause on the timezone for the agg).
Now the user gets an exception up front, and some helpful text about
why the range query didnt match, and which timezones are acceptable
This PR adds support for the Get Settings API to the java high-level rest client.
Furthermore, logic related to the retrieval of default settings has been moved from the rest layer into the transport layer and now default settings may be retrieved consistency via both the rest API and the transport API.
Upgrade to lucene-7.4.0-snapshot-1ed95c097b
This version contains:
* An Analyzer for Korean
* An IntervalQuery and IntervalsSource that retrieve minimum intervals of positional queries.
* A new API to retrieve matches (offsets and positions) of a query for a single document.
* Support for soft deletes in the index writer.
* A fixed shingle filter that handles index time synonyms.
* Support for emoji sequence in ICUTokenizer (with an upgrade to icu 61.1)
The IndexAndAliasesResolver resolves the indices and aliases for each
request and also handles local and remote indices. The current
implementation uses the ResolvedIndices class to hold the resolved
indices and aliases. While evaluating the indices and aliases against
the user's permissions, the final value for ResolvedIndices is
constructed. Prior to this change, this was done by creating a
ResolvedIndices for the first set of indices and for each additional
addition, a new ResolvedIndices object is created and merged with
the existing one. With a small number of indices and aliases this does
not pose a large problem; however as the number of indices/aliases
grows more list allocations and array copies are needed resulting in a
large amount of garbage and severely impacted performance.
This change introduces a builder for ResolvedIndices that appends to
mutable lists until the final value has been constructed, which will
ultimately reduce the amount of garbage generated by this code.
This commit fixes an issue with the data diagnostics were
empty buckets are not reported even though they should. Once
a job is reopened, the diagnostics do not get initialized from
the current data counts (especially the latest record timestamp).
The result is that if the data that is sent have a time gap compared
to the previous ones, that gap is not accounted for in the empty bucket
count.
This commit fixes that by initializing the diagnostics with the current
data counts.
Closes#30080
The current implementation starts/stops watcher using an executor. This
can result in our of order operations.
This commit reduces those executor calls to an absolute minimum in order
to be able to do state changes within the cluster state listener method,
which runs in sequence.
When a state change occurs that forces the watcher service to pause
(like no watcher index, no master node, no local shards), the service is
now in a paused state.
Pausing is a super lightweight operation, which marks the
ExecutionService as paused and waits for the currently executing watches
to finish in the background via an executor. The same applies for
stopping, the potentially long running operation is outsourced in to an
executor, as waiting for executed watches is decoupled from the current
state.
The only other long running operation is starting, where watches need to
be loaded. This is also done via an executor, but has an additional
protection by checking the cluster state version it was started with. If
another cluster state version was trying to load the watches, then this
loading will not take effect.
This PR also cleans up some unused states, like the a simple boolean in
the HistoryStore/TriggeredWatchStore marking it as started or stopped,
as this can now be caught in the execution service.
Another advantage of this approach is the fact, that now only triggered
watches are not getting executed, while watches that are run via the
Execute Watch API will still be executed regardless if watcher is
stopped or not.
Lastly the TickerScheduleTriggerEngine thread now only starts on data nodes.
Fix NPE when CumulativeSum agg encounters null/empty bucket
If the cusum agg encounters a null value, it's because the value is
missing (like the first value from a derivative agg), the path is
not valid, or the bucket in the path was empty.
Previously cusum would just explode on the null, but this changes it
so we only increment the sum if the value is non-null and finite.
This is safe because even if the cusum encounters all null or empty
buckets, the cumulative sum is still zero (like how the sum agg returns
zero even if all the docs were missing values)
I went ahead and tweaked AggregatorTestCase to allow testing pipelines,
so that I could delete the IT test and reimplement it as AggTests.

This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.

Systemd overrides should happen through /etc/systemd/system, not
directly editing the service file. This commit removes marking the
service file as configuration for rpm and deb packages.
This adds a new `_ignored` meta field which indexes and stores fields that have
been ignored at index time because of the `ignore_malformed` option. It makes
malformed documents easier to identify by using `exists` or `term(s)` queries
on the `_ignored` field.
Closes#29494
Adds two new methods to `RestClient` that take a `Request` object. These
methods will allows us to add more per-request customizable options
without creating more and more and more overloads of the `performRequest`
and `performRequestAsync` methods. These new methods look like:
```
Response performRequest(Request request)
```
and
```
void performRequestAsync(Request request, ResponseListener responseListener)
```
This change doesn't add any actual features but enables adding things like
per request timeouts and per request node selectors. This change *does*
rework the `HighLevelRestClient` and its tests to use these new `Request`
objects and it does update the docs.

Today when an index is created from shrinking or splitting an existing
index, the target index inherits almost none of the source index
settings. This is surprising and a hassle for operators managing such
indices. Given this is the default behavior, we can not simply change
it. Instead, we start by introducing the ability to copy settings. This
flag can be set on the REST API or on the transport layer and it has the
behavior that it copies all settings from the source except non-copyable
settings (a property of a setting introduced in this
change). Additionally, settings on the request will always override.
This change is the first step in our adventure:
- this flag is added here in 7.0.0 and immediately deprecated
- this flag will be backported to 6.4.0 and remain deprecated
- then, we will remove the ability to set this flag to false in 7.0.0
- finally, in 8.0.0 we will remove this flag and the only behavior will
be for settings to be copied
Currently, the only way to get the REST response for the `/_cluster/state`
call to return the `cluster_uuid` is to request the `metadata` metrics,
which is one of the most expensive response structures. However, external
monitoring agents will likely want the `cluster_uuid` to correlate the
response with other API responses whether or not they want cluster
metadata.
Add yet another warning about data loss to the introductory paragraph about the
unsafe commands. Also move this paragraph next to the details of the unsafe
commands, below the section on the `retry_failed` flag.

Clarify statements about when rebalancing takes place (i.e. it respects
settings)
Resolves#16113.
Today when a resize operation is performed, we copy the analysis,
similarity, and sort settings from the source index. It is possible for
the resize request to include additional index settings including
analysis, similarity, and sort settings. We reject sort settings when
validating the request. However, we silently ignore analysis and
similarity settings on the request that are already set on the source
index. Since it is possible to change the analysis and similarity
settings on an existing index, this should be considered a bug and the
sort of leniency that we abhor. This commit addresses this bug by
allowing the request analysis/similarity settings to override the
existing analysis/similarity settings on the target.
A previous change modified the output of the thread pool info contained

it now detects a corrupted index file and fails early the snapshot
operation.

This metric previously existed for backwards compatibility reasons
although the suggest stats were folded into search stats. This metric
was deprecated in 6.3.0 and this commit removes them for 7.0.0.
This commit adds the distribution type to the startup scripts so that we
can discern from log output and the main response the type of the
distribution (deb/rpm/tar/zip).
This commit adds the distribution flavor (default versus oss) to the
build process which is passed through the startup scripts to
Elasticsearch. This change will be used to customize the message on
attempting to install/remove x-pack based on the distribution flavor.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
The suggest stats were folded into the search stats as part of the
indices stats API in 5.0.0. However, the suggest metric remained as a
synonym for the search metric for BWC reasons. This commit deprecates
usage of the suggest metric on the indices stats API.
Similarly, due to the changes to fold the suggest stats into the search
stats, requesting the suggest index metric on the indices metric on the
nodes stats API has produced an empty object as the response since
5.0.0. This commit deprecates this index metric on the indices metric on
the nodes stats API.
The name of the bulk thread pool was renamed to "write" with "bulk" as a
fallback name. This change was made in 6.x for BWC reasons yet in 7.0.0
we are removing this fallback. This commit removes this fallback for the
write thread pool.
This commit renames the bulk thread pool to the write thread pool. This
is to better reflect the fact that the underlying thread pool is used to
execute any document write request (single-document index/delete/update
requests, and bulk requests).
With this change, we add support for fallback settings
thread_pool.bulk.* which will be supported until 7.0.0.
We also add a system property so that the display name of the thread
pool remains as "bulk" if needed to avoid breaking users.
Added an api that allows to execute an arbitrary script and a result to be returned.
```

Now that single-document indexing requests are executed on the bulk
thread pool the index thread pool is no longer needed. This commit
removes this thread pool from Elasticsearch.
As part of adding support for new API to the high-level REST client,
we added support for the `flat_settings` parameter to some of our
request classes. We added documentation that such flag is only ever
read by the high-level REST client, but the truth is that it doesn't
do anything given that settings are always parsed back into a `Settings`
object, no matter whether they are returned in a flat format or not.
It was a mistake to add support for this flag in the context of the
high-level REST client, hence this commit removes it.
We want to remove the index thread pool as it is no longer needed since
single-document indexing requests are executed as bulk requests
now. Analyze requests are also executed on the index thread pool though
and they need a thread pool to execute on. The bulk thread does not seem
like the right thread pool, let us keep that thread pool conceptually
for bulk requests and free for bulk requests. None of the existing
thread pools make sense for analyze requests either. The generic thread
pool would be a terrible choice since it has an unbounded queue and that
is a bad idea for user-facing APIs. This commit introduces a small by
default (size=1, queue_size=16) thread pool for analyze requests.
CRUD: Parsing changes for UpdateRequest (#29293)
Use `ObjectParser` to parse `UpdateRequest` so we reject unknown fields
and drop support for the `_fields` parameter because it was deprecated
in 5.x.
Control max size and count of warning headers
Add a static persistent cluster level setting
"http.max_warning_header_count" to control the maximum number of
warning headers in client HTTP responses.
Defaults to unbounded.
Add a static persistent cluster level setting
"http.max_warning_header_size" to control the maximum total size of
warning headers in client HTTP responses.
Defaults to unbounded.
With every warning header that exceeds these limits,
a message will be logged in the main ES log,
and any more warning headers for this response will be
ignored.
Historically, the bootstrap checks used 2048 as the minimum limit for
the maximum number of threads. This limit was guided by the fact that
the number of processors was artificially capped at 32. This limit was
removed in 6.0.0 and the minimum limit was raised to 4096 to accommodate
this. However, the docs were not updated and this commit addresses that
miss.
This adds an `include_type_name` option to the `indices.create`,
`indices.get_mapping` and `indices.put_mapping` APIs, which defaults to `true`.
When set to `false`, then mappings will be returned directly in the body of
the `indices.get_mapping` API, without keying them by the type name, the
`indices.create` will expect mappings directly under the `mappings` key, and
the `indices.put_mapping` will use `_doc` as a type name and fail if a `type`
is provided explicitly.

Today we report thread pool info using a common object. This means that
we use a shared set of terminology that is not consistent with the
terminology used to the configure thread pools. This holds in particular
for the minimum and maximum number of threads in the thread pool where
we use the following terminology:
thread pool info | fixed | scaling
min core size
max max size
A previous change addressed this for the nodes info API. This commit
changes the display of thread pool info in the cat thread pool API too
to be dependent on the type of the thread pool so that we can align the
terminology in the output of thread pool info with the terminology used
to configure a thread pool.
This improves the way similarities are plugged in in order to:
- reject the classic similarity on 7.x indices and emit a deprecation
warning otherwise
- reject unkwown parameters on 7.x indices and emit a deprecation
warning otherwise
Even though this breaks the plugin API, I'd like to backport to 7.x so
that users can get deprecation warnings when they are doing something
that will become unsupported in the future.

I am not sure why we have this leniency for HTTP max content length, it
has been there since the beginning
(5ac51ee93f) with no explanation of its
source. That said, our philosophy today is different than the philosophy
of the past where Elasticsearch would be quite lenient in its handling
of settings and today we aim for predictability for both users and
us. This commit removes leniency in the parsing of
http.max_content_length.
Today this part of the documentation just says that Geo queries are not 100%
accurate, but in fact we can be more precise about which kinds of queries see
which kinds of error. This commit clarifies this point.
At time of writing, GeoJSON did not enforce a specific ordering of vertices in
a polygon, but it now does. We occasionally get reports of Elasticsearch
rejecting apparently-valid GeoJSON because of badly oriented polygons, and it's
helpful to be able to point at this bit of the documentation when responding.
As follow up to #28245 , this PR removes the logic for selecting the
right start commit from the Engine constructor in favor of explicitly
trimming them in the Store, before the engine is opened. This makes the
constructor in engine follow standard Lucene semantics and use the last
commit.

#28245 has introduced the utility class`EngineDiskUtils` with a set of methods to prepare/change
translog and lucene commit points. That util class bundled everything that's needed to create and
empty shard, bootstrap a shard from a lucene index that was just restored etc.
In order to safely do these manipulations, the util methods acquired the IndexWriter's lock. That
would sometime fail due to concurrent shard store fetching or other short activities that require the
files not to be changed while they read from them.
Since there is no way to wait on the index writer lock, the `Store` class has other locks to make
sure that once we try to acquire the IW lock, it will succeed. To side step this waiting problem, this
PR folds `EngineDiskUtils` into `Store`. Sadly this comes with a price - the store class doesn't and
shouldn't know about the translog. As such the logic is slightly less tight and callers have to do the
translog manipulations on their own.
This change refactors the composite aggregation to add an execution mode that visits documents in the order of the values
present in the leading source of the composite definition. This mode does not need to visit all documents since it can early terminate
the collection when the leading source value is greater than the lowest value in the queue.
Instead of collecting the documents in the order of their doc_id, this mode uses the inverted lists (or the bkd tree for numerics) to collect documents
in the order of the values present in the leading source.
For instance the following aggregation:
```
"composite" : {
"sources" : [
{ "value1": { "terms" : { "field": "timestamp", "order": "asc" } } }
],
"size": 10
}
```
... can use the field `timestamp` to collect the documents with the 10 lowest values for the field instead of visiting all documents.
For composite aggregation with more than one source the execution can early terminate as soon as one of the 10 lowest values produces enough
composite buckets. For instance if visiting the first two lowest timestamp created 10 composite buckets we can early terminate the collection since it
is guaranteed that the third lowest timestamp cannot create a composite key that compares lower than the one already visited.
This mode can execute iff:
* The leading source in the composite definition uses an indexed field of type `date` (works also with `date_histogram` source), `integer`, `long` or `keyword`.
* The query is a match_all query or a range query over the field that is used as the leading source in the composite definition.
* The sort order of the leading source is the natural order (ascending since postings and numerics are sorted in ascending order only).
If these conditions are not met this aggregation visits each document like any other agg.
The rank_eval documentation was missing an explanation of the parameter
`k` that controls the number of top hits that are used in the ranking evaluation.

This commit adds a new setting `cluster.persistent_tasks.allocation.enable`
that can be used to enable or disable the allocation of persistent tasks.
The setting accepts the values `all` (default) or `none`. When set to
none, the persistent tasks that are created (or that must be reassigned)
won't be assigned to a node but will reside in the cluster state with
a no "executor node" and a reason describing why it is not assigned:
```
"assignment" : {
"executor_node" : null,
"explanation" : "persistent task [foo/bar] cannot be assigned [no
persistent task assignments are allowed due to cluster settings]"
}
```
This will reject mapping updates to the `_default_` mapping with 7.x indices
and still emit a deprecation warning with 6.x indices.

This is a follow up to a previous change which set the error file path
for the package distributions. The observation here is that we always
set the working directory of Elasticsearch to the root of the

directory, similar to the package distributions.
This is a follow up to a previous change which set the heap dump path

Adds support for triple quoted strings to the documentation test

The Java API documentation for index administration currenty is wrong because
the PutMappingRequestBuilder#setSource(Object... source) an

documentation integration tests so we detect compile and runtime issues earlier.

By the time the master branch is released the deprecated url
parameters in the `/_cache/clear` API will have been deprecated
for a couple of minor releases. Since master will be the next
major release we are fine with removing these parameters.
Currently we have a fairly complicated logic in the engine constructor logic to deal with all the
various ways we want to mutate the lucene index and translog we're opening.
We can:
1) Create an empty index
2) Use the lucene but create a new translog
3) Use both
4) Force a new history uuid in all cases.
This leads complicated code flows which makes it harder and harder to make sure we cover all the
corner cases. This PR tries to take another approach. Constructing an InternalEngine always opens
things as they are and all needed modifications are done by static methods directly on the
directory, one at a time.
We today support a global `indexed_chars` processor parameter. But in some cases, users would like to set this limit depending on the document itself.
It used to be supported in mapper-attachments plugin by extracting the limit value from a meta field in the document sent to indexation process.
We add an option which reads this limit value from the document itself
by adding a setting named `indexed_chars_field`.
Which allows running:
```
PUT _ingest/pipeline/attachment
{
"description" : "Extract attachment information. Used to parse pdf and office files",
"processors" : [
{
"attachment" : {
"field" : "data",
"indexed_chars_field" : "size"
}
}
]
}
```
Then index either:
```
PUT index/doc/1?pipeline=attachment
{
"data": "BASE64"
}
```
Which will use the default value (or the one defined by `indexed_chars`)
Or
```
PUT index/doc/2?pipeline=attachment
{
"data": "BASE64",
"size": 1000
}
```

The current docs on [Indices APIs: PUT Mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html) suggests that a having number of different mapping types per index is still possible in elasticsearch versions > 6.0.0 although they have been [removed](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html). The console code has already been updated accordingly but notes (2) and (3) on the console code still name the `user` mapping type.
This PR updates the list with notes after the console code, as well as the first sentence of the docs
to avoid confusion. Also, I have removed the second command from the console code as it no
longer holds any value if the docs are solely on the `_doc` mapping.
The docs state that `_gce_` is recommended but the code sample states
that `_gce:hostname_` is recommended. This aligns the code sample with
the documentation. Also replace `type` with `zen.hosts_provider` as
discovery.type was removed in #25080.
With this commit we reduce heap usage of the ingest-geoip plugin by
memory-mapping the database files. Previously, we have stored these
files gzip-compressed but this has resulted that data are loaded on the
heap.

The original example resulted in a 400 error due to the example being `-` separated instead of the default `.` separation.
```

Increase the default limit of `index.highlight.max_analyzed_offset` to 1M instead of previous 10K.
Enhance an error message when offset increased to include field name, index name and doc_id.

* Clarifies how the query_string splits textual part to build a query
Whitespaces are not considered as operators anymore in 6x but the documentation is not clear about it.
This commit changes the example in the documentation and adds a note regarding whitespaces and operators.
Closes#28719
Values for the network.host setting can often contain a colon which is a
character that is considered special by YAML (these arise in IPv6
addresses and some of the special tags like ":ipv4"). As such, these
values need to be quoted or a YAML parser will be unhappy with
them. This commit adds a note to the docs regarding this.
* Reject regex search if regex string is too long (#28344)
* Add docs
* Introduce index level setting `index.max_regex_length`
to control the maximum length of the regular expression
Closes#28344
Similarly to what has been done for s3 and azure, this commit removes
the repository settings `application_name` and `connect/read_timeout`
in favor of client settings. It introduce a GoogleCloudStorageClientSettings
class (similar to S3ClientSettings) and a bunch of unit tests for that,
it aligns the documentation to be more coherent with the S3 one, it
documents the connect/read timeouts that were not documented at all and
also adds a new client setting that allows to define a custom endpoint.
We previously specified the -server flag to force the JVM to use the
server JVM. This is the default on all the systems that we support when
using a 64-bit JVM (and we no longer support 32-bit JVMs). There was
some trouble with this flag for the Windows service since procrun did
not understand what to do with it; as such, we had to filter this flag
out in the service. When we migrated to parsing JVM options in Java (via
the JVM options parser) we simplified this situation and removed
specifying the -server flag. This commit removes a leftover statement
that we are forcing the server JVM.

The node stats API enables filtlering the top-level stats for only
desired top-level stats. Yet, this was never enabled for adaptive
replica selection stats. This commit enables this. We also add setting
these stats on the request builder, and fix an inconsistent name in a
setter.

The Windows service will use a private temporary directory under the
user that is performing the installation. In cases when the service will
run as a different user, operators need a method to set this temporary
directory elsewhere. We have such a mechanism, so this commit merely
adds a note to the documentation on how to utilize it.

Elasticsearch 6.x indices do not allow multiple types index. Instead, they use "_doc" as default if created internally (Elasticsearch), or "doc" default if sent by Logstash.
Currently the Translog constructor is capable both of opening an existing translog and creating a
new one (deleting existing files). This PR separates these two into separate code paths. The
constructors opens files and a dedicated static methods creates an empty translog.
This directory was removed from plugins in #28589, but docs still
referenced it. This commit cleans up the plugin author docs to no longer
refer to it.
* Search option terminate_after does not handle post_filters and aggregations correctly
This change fixes the handling of the `terminate_after` option when post_filters (or min_score) are used.
`post_filter` should be applied before `terminate_after` in order to terminate the query when enough document are accepted
by the post_filters.
This commit also changes the type of exception thrown by `terminate_after` in order to ensure that multi collectors (aggregations)
do not try to continue the collection when enough documents have been collected.
Closes#28411
We do want to keep this functionality in the future and we provide support for it.
This change is a first step towards replacing the `synonym` token filter with `synonym_graph`.
Currently the callouts for this section are below all the examples, making it
harder to relate them to the snippets. Instead they should be moved closer
to the examples.
* [DOCS] expand examples on providing mappings for create index and put mapping
The create index API and put mappings API docs the for high-level Java REST client didn't have a lot of info on how to provide mappings. This commit adds some examples.
This commit splits the async execution documentation into 2 parts, one
for the async method itself and one for the action listener. This allows
to add more doc and to use CountDownLatches in doc tests to wait for
asynchronous operations to be completed before moving to the next test.
It also renames few files.

Adds allow_partial_search_results flag to search requests with default setting = true.
When false, will error if search either timeouts, has partial errors or has missing shards rather
than returning partial search results. A cluster-level setting provides a default for search requests with no flag.
Closes#27435
The `terms` query is really designed for filtering and highlighting it might
cause performance issues if it wraps many terms, so I am documenting
highlighting these queries as a best-effort only.
Closes#28099
This change adds support for the new ranking evaluation API to the High Level Rest Client.
This mostly means adding support for parsing the various response objects back from the
REST representation. It includes one change to the response syntax where previously we didn't
print the type of the metric details section but we now need it to pick the right parser to
parse this section back.
Closes#28198
This adds the ability to index term prefixes into a hidden subfield, enabling prefix queries to be run without multitermquery rewrites. The subfield reuses the analysis chain of its parent text field, appending an EdgeNGramTokenFilter. It can be configured with minimum and maximum ngram lengths. Query terms with lengths outside this min-max range fall back to using prefix queries against the parent text field.
The mapping looks like this:
"my_text_field" : {
"type" : "text",
"analyzer" : "english",
"index_prefix" : { "min_chars" : 1, "max_chars" : 10 }
}

Cluster settings shouldn't leak into the next test.
I played with failing the test if it left over any settings but that
felt like it added more ceremony then it was worth. The advantage is
that any test that intentionally wants to leave settings in place after
the test would fail and require looking at but, so far as I can tell, we
don't have any such tests.
Clear the disk watermark after the snippet showing users how to set it.
Without this our tests will fail if the disks have less than 10GB free.

This pull request replaces the jvm-example plugin (from the jvm/site plugins era) by two new plugins: a custom-settings that shows how to register and use custom settings (including secured settings) in a plugin, and rest-handler plugin that shows how to register a rest handler.
The two plugins now reside in the plugins/examples project. They can serve as sample plugins for users, a special attention has been put on documentation. The packaging tests have been adapted to use the custom-settings plugin.
The implementation maintains the order of the original requests yet this
functionality is not documented. This commit adds a note to the docs
regarding the ordering of responses to an multi-get request.

This PR removes previously deprecated `isShardsAcked()` method in
favour of `isShardsAcknowledged()` on `CreateIndexResponse`, `CreateIndexClusterStateUpdateResponse` and `RolloverResponse`
Related to #27784
Follow-up of #27819
This change adds the `after_key` of a composite aggregation directly in the response.
It is redundant when all buckets are not filtered/removed by a pipeline aggregation since in this case the `after_key` is always the last bucket
in the response. Though when using a pipeline aggregation to filter composite buckets, the `after_key` can be lost if the last bucket is filtered.
This commit fixes this situation by always returning the `after_key` in a dedicated section.
This change adds a note in the `terms` aggregation that explains how to retrieve **all**
terms (or all combinations of terms in a nested agg) using the `composite` aggregation.
This commit adds the ability to specify a date format on the `date_histogram` composite source.
If the format is defined, the key for the source is returned as a formatted date.
Closes#27923
The use of the phrase "translog" vs "transaction log" was inconsistent, and
it was apparently unclear that the translog was stored on every shard copy.
