This adds a force-merge step to the searchable snapshot action, enabled by default,
but parameterizable using the `force_merge-index" optional boolean.
eg.
```
PUT _ilm/policy/my_policy
{
"policy": {
"phases": {
"cold": {
"actions": {
"searchable_snapshot" : {
"snapshot_repository" : "backing_repo",
"force_merge_index": true
}
}
}
}
}
}
```

"Transitive" is technically ok here but it's an overloaded word and it's
not immediately clear which meaning is intended so this log message
always makes me do a double-take. I think both "transient" and
"transitory" are clearer, with "transient" being the usual choice.
This suite is still occasionally failing with a timeout on macOS.
Suggest further increasing this timeout until this suite is broken up.

Uses `my-data-stream` in place of `logs` for data stream examples.
This provides a more intuitive experience for users that copy/paste
their own values into snippets.
* [ML] have DELETE analytics ignore stats failures and clean up unused stats (#60776)
When deleting an analytics configuration, the request MIGHT fail if
the .ml-stats index does not exist or is in strange state (shards unallocated).
Instead of making the request fail, we should log that we were unable to delete the stats docs and then
have them cleaned up in the 'delete_expire_data' janitorial process
remove test, scripts are excluded in the change collector, the test is a leftover from a previous
solution of #57332, which has been discarded

When an exception is thrown during test inference we are
not including the cause message in our logging. This commit
addresses this issue.
Backport of #60749
This pull request adds recovery state tracking for Searchable Snapshots.
In order to track recoveries for searchable snapshot backed indices, this pull
request adds a new type of RecoveryState.
This newRecoveryState instance is able to deal with the
small differences that arise during Searchable snapshots recoveries.
Those differences can be summarized as follows:
- The Directory implementation that's provided by SearchableSnapshots mark the
snapshot files as reused during recovery. In order to keep track of the
recovery process as the cache is pre-warmed, those files shouldn't be marked
as reused.
- Once the shard is created, the cache starts its pre-warming phase, meaning that
we should keep track of those downloads during that process and tie the recovery
to this pre-warming phase. The shard is considered recovered once this pre-warming
phase has finished.
Backport of #60505
disable optimizations when using scripts in group_by, when scripts using scripts we can not predict
the outcome and we have no query counterpart. Other optimizations for other group_by's are not
affected.
fixes#57332
implements a test suite for testing continuous transform with randomization in terms of mappings,
index settings, transform configuration. Add a test case for terms and date histogram. The test
covers:
- continuous mode with several checkpoints created
- correctness of results
- optimizations (minimal necessary writes)
- permutations of features (index settings, aggs, data types, index or data stream)
When the RBACEngine authorizes scroll searches it sets the index access control
to the very limiting IndicesAccessControl.ALLOW_NO_INDICES value.
This change will set it to the value for the index access control that was produced
during the authorization of the initial search that created the scroll,
which is now stored in the scroll context.
Implements license degradation behavior for searchable snapshots. Snapshot-backed shards are failed when the license becomes invalid, and shards won't be reallocated. After valid license is put in place again, shards are allocated again.
This commit removes the body property from the
indices.create_data_stream.json REST API spec
as the API does not support sending a body.
Update the description of the API to remove
that a data stream can be updated with the
API - data streams can only be created with
this API and attempting to update yields a
`resource_already_exists_exception`.
Closes#60704
(cherry picked from commit 2cab2e0ee094769852df31566dbe22b5df59d900)
Currently, validation of mappers (checking that cross-references are correct, limits on
field name lengths and object depths, multiple definitions, etc) is performed by the
MapperService. This means that any mapper-specific validation, for example that done
on the CompletionFieldMapper, needs to be called specifically from core server code,
and so we can't add validation to mappers that live in plugins.
This commit reworks the validation framework so that mapper-specific validation is
done on the Mapper itself. Mapper gets a new `validate(MappingLookup)`
method (already present on `MetadataFieldMapper` and now pulled up to the parent
interface), which is called from a new `DocumentMapper.validate()` method. All
the validation code currently living on `MapperService` moves either to individual
mapper implementations (FieldAliasMapper, CompletionFieldMapper) or into
`MappingLookup`, an altered `DocumentFieldMappers` which now knows about
object fields and can check for duplicate definitions, or into DocumentMapper
which handles soft limit checks.
* Merge test runner task into RestIntegTest (#60261)

We have various ways of copying between two streams and handling thread-local
buffers throughout the codebase. This commit unifies a number of them and
removes buffer allocations in many spots.
This commit changes TokenAuthIntegTests so all occurrences of
assertThat(x.size(), equalTo(0));
become
assertThat(x, empty());
This means that the assertion failure message will include the
contents of the list (`x`) instead of just its size, which
facilitates easier failure diagnosis.

This commit does three things:
* Removes all Copyright/license headers for the build.gradle files under x-pack. (implicit Apache license)
* Removes evaluationDependsOn(xpackModule('core')) from build.gradle files under x-pack
* Removes a place holder test in favor of disabling the test task (in the async plugin)
Closing a regular index and mounting a snapshot-backed index into that existing index does not clean the existing index
folders of those preexisting shards.
This PR removes the existing Lucene / translog files once the searchable snapshot shard is starting up. Future PRs will
make reuse of the existing index files to populate the cache.
When a new cluster starts, the HTTP layer becomes ready to accept incoming
requests while the basic license is still being populated in the background.
When a get license request comes in before the license is ready, it can get
404 error. This PR fixes it by either wrap the license check in assertBusy or
ensure the license is ready before perform the check.
This is a backport for both #60498 and #60573
For consistency reasons (and reducing the overload of IllegalArgumentException)
this changes the exception thrown when trying to create a data stream
that already exists.

* SQL: Add option to provide the delimiter for the CSV format (#59907)
* Add option to provide the delimiter to the CSV fmt
This adds the option to provide the desired character as the separator
for the CSV format (the default remains comma).
A set of characters are excluded though - like CR, LF, `"` - to avoid
slipping onto the CSV-dialects slope. The tab is also forbidden, the
user needs to choose the "tsv" format explicitely.
Update the doc to make it clear that the textual CSV, TSV and TXT
formats pass the cursor back to the user through the Cursor HTTP header.
