DOC: Add examples to the SQL docs (#31633)
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).

Add support for AWS session tokens (#30414)
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

Account for XContent overhead in in-flight breaker
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.

Nik Everett 0522c6644d Docs: Remove duplicate test setup
The range docs had an introductory section that described how to set up
and index *and* a test setup section in `docs/build.gradle` that
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.

Node selector per client rather than per request (#31471)
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.

Docs: Use the default distribution to test docs (#31251)
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.

Percentile/Ranks should return null instead of NaN when empty (#30460)
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.

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.

[INGEST] Interrupt the current thread if evaluation grok expressions take too long (#31024)
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

LLClient: Support host selection (#30523)
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.

* High-level client: list tasks failure to not lose nodeId

This commit reworks testing for `ListTasksResponse` so that random
fields insertion can be tested and xcontent equivalence can be checked
too. Proper exclusions need to be configured, and failures need to be
tested separately. This helped finding a little problem, whenever there
is a node failure returned, the nodeId was lost as it was never printed
out as part of the exception toXContent.

* added comment

* merge from master

* re-work CancelTasksResponseTests to separate XContent failure cases from non-failure cases

* remove duplication of logic in parser creation

* code review changes

* refactor TasksClient to support RequestOptions

* add tests for parent task id

* address final PR review comments, mostly formatting and such

Fix index prefixes to work with span_multi (#31066)
* 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.

Index phrases (#30450)
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.

Add missing_bucket option in the composite agg (#29465)
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:

Itamar Syn-Hershko 5f172b6795 [Feature] Adding a char_group tokenizer (#24186)
=== 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 ]```

Default to one shard (#30539)
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).

Docs: Test examples that recreate lang analyzers (#29535)
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.

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.

Watcher: Increase HttpClient parallel sent requests (#30130)
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.

Do not fail snapshot when deleting a missing snapshotted file (#30332)
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.

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`

[Rollup] Validate timezone in range queries (#30338)
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

Security: reduce garbage during index resolution (#30180)
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.

[ML] Account for gaps in data counts after job is reopened (#30294)
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.

Watcher: Make start/stop cycle more predictable and synchronous (#30118)
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 (#29641)
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.

Network: Remove http.enabled setting (#29601)
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.

REST Client: Add Request object flavored methods (#29623)
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.

Allow copying source settings on resize operation (#30255)
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

Do not ignore request analysis/similarity on resize (#30216)
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.

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.

Introduce analyze thread pool (#29541)
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.

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.

Align cat thread pool info to thread pool config (#29195)
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.

Fold EngineDiskUtils into Store, for better lock semantics (#29156)
#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.

Optimize the composite aggregation for match_all and range queries (#28745)
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.
