This commit adjusts the following APIs so now they not only support an `_all` case, but wildcard patterned Ids as well.
- `GET _ml/calendars/<calendar_id>/events`
- `GET _ml/calendars/<calendar_id>`
- `GET _ml/anomaly_detectors/<job_id>/model_snapshots/<snapshot_id>`
- `DELETE _ml/anomaly_detectors/<job_id>/_forecast/<forecast_id>`
We removed index-time boosting back in 5x, and we no longer document the 'boost'
parameter on any of our mapping types. However, it is still possible to define an
index-time boost on a field mapper for a surprisingly large number of field types, and
they even have an effect (sometimes, on some queries).
As a first step in finally removing all traces of index time boosting, this comment emits
a deprecation warning whenever a boost parameter is found on a mapping definition.
* [ML] Add new include flag to GET inference/<model_id> API for model training metadata (#61922)
Adds new flag include to the get trained models API
The flag initially has two valid values: definition, total_feature_importance.
Consequently, the old include_model_definition flag is now deprecated.
When total_feature_importance is included, the total_feature_importance field is included in the model metadata object.
Including definition is the same as previously setting include_model_definition=true.
* fixing test
* Update x-pack/plugin/core/src/test/java/org/elasticsearch/xpack/core/ml/action/GetTrainedModelsRequestTests.java
In #62357 we introduced an additional optimization that allows us to skip the
most of the fetch phase early if no results are found. This change caused
some cancellation test failures that were relying on definitive cancellation
during the fetch phase. This commit adds an additional quick cancellation
check at the very beginning of the fetch phase to make cancellation process
more deterministic.
Fixes#62530
Changes the way we collecting ordinals in the Cardinality aggregation from Lucene FixedBitSet to BitArray. The benefit is that BitArray is tracked by our Circuit breakers so it is safer.
Today when a snapshot restore is aborted (for example when the index is
explicitly deleted) while the restoration of the files from the repository has
already started the file restores are not interrupted. It means that Elasticsearch
will continue to read the files from the repository and will continue to write
them to disk until all files are restored; the store will then be closed and
files will be deleted from disk at some point but this can take a while. This
will also take some slots in the SNAPSHOT thread pool too. The Recovery
API won't show any files actively being recovered, the only notable
indicator would be the active threads in the SNAPSHOT thread pool.
This commit adds a check before reading a file to restore and before
writing bytes on disk so that a closing store can be detected more
quickly and the file recovery process aborted. This way the file
restores just stops and for most of the repository implementations
it means that no more bytes are read (see #62370 for S3), finishing
threads in the SNAPSHOT thread pool more quickly too.
Async search tests can take more than one minute due to the excessive trace logs.
And the point in time in the tests can be expired the midway.
Closes#62451
This test (in-part) verifies that snapshot creation is not
retried on master fail-over once a snaphot has been started already.
Unless we wait for the snapshot creation to show up in the cluster
state before failing the master node though, we could run into a
race where the snapshot wasn't yet in the cluster state and a retry goes through
successfully.
a dateformatter can be created with a list of parsers which are iterated
during parsing and the first one that passes will return a parsed date.
DateMathParser should do the same, when created based on a list of
non-rounding parsers it should also iterate over all of them - it is at
the moment only taking first element
closing #62207
The underlying issue was fixed a while ago in Lucene:
https://issues.apache.org/jira/browse/LUCENE-9517
and went away when lucene snapshot version was upgraded.
Also the name of the index to rollover had to be slightly changed,
so that it doesn't collide with data stream template's namespace.
(a regular index can't be created in the namespace that is managed
by a template that creates data streams)
Closes#62043
Expressions like `1 = 2 = 3 = 4` or `1 < 2 = 3 >= 4` were treated with
leftmost priority: ((1 = 2) = 3) = 4 which can lead to confusing
results. Since such expressions don't make so much change for EQL
filters we disallow them in the parser to prevent unexpected results
from their bad usage.
Major DBs like PostgreSQL and Oracle also disallow them in their SQL
syntax. (counter example would be MySQL which interprets them as we did
before with leftmost priority).

The purpose for this change is to allow validation of queries without
having to actually execute them. The optimizer already picks up this
case.

(cherry picked from commit 675889559b2f96a0c1faa6fc84fd537148ba2cce)
A recent AWS SDK upgrade has introduced a new source of spurious `WARN`
logs when the security manager prevents access to the user's home
directory and therefore to `$HOME/.aws/config`. This is the behaviour we
want, and it's harmless and handled by the SDK as if the config doesn't
exist, so this log message is unnecessary noise. This commit suppresses
this noisy logging by default.

This commit address some build failures from the perspective of Intellij.
These changes include:
* changing an order of a dependency definition that seems to can cause Intellij build to fail.
* introduction of an abstract class out of the test source set (seems to be an issue sharing
classes cross projects with non-standard source sets.
* a couple of missing dependency definitions (not sure how the command line worked prior to this)
Removes methods that were no longer used regarding version 5.4 doc ids of ModelState.
Also adds clean up of 5.4 model state and quantile docs in the daily maintenance.

Backport of #62527 to 7.x branch.
This commit adds validation that prohibits the creation of regular indices
in the namespace of templates with data streams enabled.
It shouldn't be possible to create ordinary indices when the name of the index
matches with a composable index template that enables data streams. Auto creation
has logic that creates data streams instead of regular indices. However validation
logic for the create index api was missing.
Faster sequential access for stored fields
Spinoff of #61806
Today retrieving stored fields at search time is optimized for random access.
So we make no effort to keep state in order to not decompress the same data
multiple times because two documents might be in the same compressed block.
This strategy is acceptable when retrieving a top N sorted by score since
there is no guarantee that documents will be on the same block.
However, we have some use cases where the document to retrieve might be
completely sequential:
Scrolls or normal search sorted by document id.
Queries on Runtime fields that extract from _source.
This commit exposes a sequential stored fields reader in the
custom leaf reader that we use at search time.
That allows to leverage the merge instances of stored fields readers that
are optimized for sequential access.
This change focuses on the fetch phase for now and leverages the merge instances
for stored fields only if all documents to retrieve are adjacent.
Applying the same logic in the source lookup of runtime fields should
be trivial but will be done in a follow up.
The speedup on queries sorted by doc id is significant.

Closes#62024
FetchSubPhase#getProcessor currently takes a SearchLookup parameter. This
however is only needed by a couple of subphases, and will almost certainly change in
future as we want to simplify how fetch phases retrieve values for individual hits.
To future-proof against further signature changes, this commit moves the SearchLookup
reference into FetchContext instead.
Currently we throw an error if stored fields are disabled, but hit version metadata is
requested on a search. This doesn't make much sense, as the version information
is stored in docvalues and so has no connection with stored fields.
This commit removes the link between the two, allowing version metadata to be loaded
even when stored fields are disabled in a request.
Fixes#62456
The data frame structure in c++ has a limit on 2^32 documents. This commit
adds a check that the number of documents involved in the analysis are
less than that and fails to start otherwise. That saves the cost of
reindexing when it is unnecessary.
Backport of #62547
In #57666 we changed when null_value was parsed for ip and date fields. Previously,
the null value was stored as a string, and parsed into a date or InetAddress whenever
a document containing a null value was encountered. Now, the values are parsed when
the mappings are built, which means that bad values are detected up front; if you try and
add a mapping with a badly-parsed ip or date for a null_value, the mapping will be
rejected.
This causes problems for upgrades in the case when you have a badly-formed null_value
in a pre-7.9 cluster. This commit fixes the upgrade case by changing the logic to only
logging a warning on the badly formed value, replicating the earlier behaviour.
Fixes#62363
The AssertingInputStream in S3BlobContainerRetriesTests verifies
that InputStream are either fully consumed or aborted, but the
eof flag is only set when the underlying stream returns it.
When buffered read are executed and when the exact number
of remaining bytes are read, the eof flag is not set to true. Instead
the test should rely on the total number of bytes read to know if
the stream has been fully consumed.
Close#62390
This adds ILM support for automatically migrating the managed
indices between data tiers.
This proposal makes use of a MigrateAction that is injected
(similar to how the Unfollow action is injected) in phases that
don't define index allocation rules using the AllocateAction or
don't explicitly define the MigrateAction itself (regardless if it's
enabled or disabled).
