In real deployments it is important that clusters are properly configured to
avoid accidentally forming multiple independent clusters at cluster
bootstrapping time. However we also expect to be able to unpack Elasticsearch
and start up one or more nodes without any up-front configuration, and have
them do their best to find each other and form a cluster after a few seconds.
This change adds a delayed automatic bootstrapping process to nodes that start
up with no relevant settings set to support the desired out-of-the-box
experience without compromising safety in properly-configured deployments.
* Add deprecation warnings to `Rest*TermVectorsAction`, plus tests in `Rest*TermVectorsActionTests`.
* Deprecate relevant methods on the Java HLRC requests/ responses.
* Update documentation (for both the REST API and Java HLRC).
* For each REST yml test, create one version without types, and another legacy version that retains types (called *_with_types.yml).
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

The current response format is:
```
{
"pattern1": {
...
},
"pattern2": {
...
}
}
```
The new format is:
```
{
"patterns": [
{
"name": "pattern1",
"pattern": {
...
}
},
{
"name": "pattern2",
"pattern": {
...
}
}
]
}
```
This format is more structured and more friendly for parsing and generating specs.
This is a breaking change, but it is better to do this now while ccr
is still a beta feature than later.
Follow up from #36049
This change adds a soft limit to open scroll contexts that can be controlled with the dynamic cluster setting `search.max_open_scroll_context` (defaults to 500).
When building a query Lucene distinguishes two cases, queries that require to produce a score and queries that only need to match. We cloned this mechanism in the QueryBuilders in order to be able to produce different queries based on whether they need to produce a score or not. However the only case in es that require this distinction is the BoolQueryBuilder that sets a different minimum_should_match when a `bool` query is built in a filter context..
This behavior doesn't seem right because it makes the matching of `should` clauses different when the score is not required.
Closes#35293
The new limit on the number of open shards in a cluster may be
interpreted by users as a sizing recommendation, but it is not. This
clarifies in the documentation that this is a safety limit, not a
recommendation.
This commit documents how Index Lifecycle Management
interacts with snapshot/restore, and documents a workaround
for situations in which ILM should not immediately resume
managing an index after it is restored.
A number of tokenfilters can produce multiple tokens at the same position. This
is a problem when using token chains to parse synonym files, as the SynonymMap
requires that there are no stacked tokens in its input.
This commit ensures that when used to parse synonyms, these tokenfilters either produce
a single version of their input token, or that they throw an error when mappings are
generated. In indexes created in elasticsearch 6.x deprecation warnings are emitted in place
of the error.
* asciifolding and cjk_bigram produce only the folded or bigrammed token
* decompounders, synonyms and keyword_repeat are skipped
* n-grams, word-delimiter-filter, multiplexer, fingerprint and phonetic throw errors

Move classes under the same package to avoid internal classes being
exposed to the outside. Remove public visibility outside 3 classes:
EsDriver, EsDataSource and EsTypes.
The driver only has one package, namely org.elasticsearch.xpack.sql.jdbc

destination
Fix#35437
* [Rollup] Add more diagnostic stats to job
To help debug future performance issues, this adds the
min/max/avg/count/total latencies (in milliseconds) for search
and bulk phase. This latency is the total service time including
transfer between nodes, not just the `took` time.
It also adds the count of search/bulk failures encountered during
runtime. This information is also in the log, but a runtime counter
will help expose problems faster
* review cleanup
* Remove dead ParseFields
`ScriptDocValues#getValues` was added for backwards compatibility but no
longer needed. Scripts using the syntax `doc['foo'].values` when
`doc['foo']` is a list should be using `doc['foo']` instead.

MultiSearchRequests issues through `_msearch` now validate all keys

This removes the option to run a cluster without enforcing the
cluster-wide shard limit, making strict enforcement the default and only
behavior. The limit can still be adjusted as desired using the cluster
settings API.
Add GREATEST(expr1, expr2, ... exprN) and LEAST(expr1, expr2, exprN)
functions which are in the family of CONDITIONAL functions.
Implementation follows PostgreSQL behaviour, so the functions return
`NULL` when all of their arguments evaluate to `NULL`.
Renamed `CoalescePipe` and `CoalesceProcessor` to `ConditionalPipe` and
`ConditionalProcessor` respectively, to be able to reuse them for
`Greatest` and `Least` evaluations. To achieve that `ConditionalOperation`
has been added to differentiate between the functionalities at execution
time.
Closes: #35878
This operator handles nulls in different way than the normal `=`.
If one of the operants is `null` and the other not it returns `false`.
If both operants are `null` it returns `true`. Therefore in contrary to
`=`, which returns `null` if at least one of the operants is `null`, this one
never returns `null` as a result.
Closes: #35871
This endpoint was not previously documented as it was not
particularly useful to end users. However, since the HLRC
will support the endpoint we need some documentation to
link to.
The purpose of the endpoint is to provide defaults and
limits used by ML. These are needed to fully understand
configurations that have missing values because the missing
value means the default should be used.

The ICU plugin provides the building blocks of an analysis chain, but doesn't actually have a prebuilt analyzer. It would be a better for users if there was a simple analyzer that they could use out of the box, and also something we can point to from the CJK Analyzer docs as a superior alternative.

This commit adds a rest endpoint for freezing and unfreezing an index.
Among other cleanups mainly fixing an issue accessing package private APIs
from a plugin that got caught by integration tests this change also adds
documentation for frozen indices.
Note: frozen indices are marked as `beta` and available as a basic feature.

RolloverStep previously had a name of "attempt_rollover", which was
inconsistent with all other step names due it its use of an underscore
instead of a dash.
* Deprecate types in count requests.
* Move RestCountAction to the 'search' package.
* Deprecate types in multi search requests.
* Add tests for types deprecation in the _search endpoint.
RolloverAction will now periodically check the rollover conditions using
the Rollover API with the dry_run option as an AsyncWaitStep, then run
the rollover itself by calling the Rollover API with no conditions,
which will always roll over, as an AsyncActionStep. This will resolve
race condition issues in policies using RolloverAction.

The docs are not resilient to timing issues where the ILM metadata is not set on newly
created indices, so we shouldn't be so strict on the returned response
The documentation of `search_after` recommends to use the `_id`
field as a tiebreaker for the sort without warning against
the additional memory required. This change changes the recommandation
to use a copy of the `_id` field with doc_values enabled.
This adds a `wait_for_completion` flag which allows the user to block
the Stop API until the task has actually moved to a stopped state,
instead of returning immediately. If the flag is set, a `timeout` parameter
can be specified to determine how long (at max) to block the API
call. If unspecified, the timeout is 30s.
If the timeout is exceeded before the job moves to STOPPED, a
timeout exception is thrown. Note: this is just signifying that the API
call itself timed out. The job will remain in STOPPING and evenutally
flip over to STOPPED in the background.
If the user asks the API to block, we move over the the generic
threadpool so that we don't hold up a networking thread.
