Composable templates with exact matches, can match with the data stream name, but not with the backing index name.
Also if the backing index naming scheme changes, then a composable template may never match with a backing index.
In that case mappings and settings may not get applied.
Added data streams overview page and
an introduction to data streams.

Deleting expired data can take a long time leading to timeouts if there
are many jobs. Often the problem is due to a few large jobs which
prevent the regular maintenance of the remaining jobs. This change adds
a job_id parameter to the delete expired data endpoint to help clean up
those problematic jobs.
This PR adds the initial Java side changes to enable
use of the per-partition categorization functionality
added in elastic/ml-cpp#1293.
There will be a followup change to complete the work,
as there cannot be any end-to-end integration tests
until elastic/ml-cpp#1293 is merged, and also
elastic/ml-cpp#1293 does not implement some of the
more peripheral functionality, like stop_on_warn and
per-partition stats documents.
The changes so far cover REST APIs, results object
formats, HLRC and docs.
* Manually Craft CreateSnapshotRequest to fix BwC Test
We can't use the high level create snapshot request any longer
since we changed some of its default parameters in `8` and those
are not understood by older versions like `7.4`.
Closes#57650
When we force delete a DF analytics job, we currently first force
stop it and then we proceed with deleting the job config.
This may result in logging errors if the job config is deleted
before it is retrieved while the job is starting.
Instead of force stopping the job, it would make more sense to
try to stop the job gracefully first. So we now try that out first.
If normal stop fails, then we resort to force stopping the job to
ensure we can go through with the delete.
In addition, this commit introduces `timeout` for the delete action
and makes use of it in the child requests.
#47711 and #47246 helped to validate that monitoring settings are
rejected at time of setting the monitoring settings. Else an invalid
monitoring setting can find it's way into the cluster state and result
in an exception thrown [1] on the cluster state application (there by
causing significant issues). Some additional monitoring settings have
been identified that can result in invalid cluster state that also
result in exceptions thrown on cluster state application.
All settings require a type of either http or local to be
applicable. When a setting is changed, the exporters are automatically
updated with the new settings. However, if the old or new settings lack
of a type setting an exception will be thrown (since exporters are
always of type 'http' or 'local'). Arguably we shouldn't blindly create
and destroy new exporters on each monitoring setting update, but the
lifecycle of the exporters is abit out the scope this PR is trying to
address.
This commit introduces a similar methodology to check for validity as
#47711 and #47246 but this time for ALL (including non-http) settings.
Monitoring settings are not useful unless there an exporter with a type
defined. The type is used as dependent setting, such that it must
exist to set the value. This ensures that when any monitoring settings
changes that they can only get added to cluster state if the type
exists. If the type exists (and the other validations pass) then the
exporters will get re-built and the cluster state remains valid.
Tests have been included to ensure that all dynamic monitoring settings
have the type as dependent settings.

Moves the source filtering example snippets form the "Request body
search" API docs page to the "Return fields in a search" section of the
"Run a search" page.
Merges the remaining implementation of `significant_terms` into `terms`
so that we can more easilly make them work properly without
`asMultiBucketAggregator` which *should* save memory and speed them up.

rewrite config on update if either version is outdated, credentials change,
the update changes the config or deprecated settings are found. Deprecated
settings get migrated to the new format. The upgrade can be easily extended to
do any necessary re-writes.

Today `GET _cluster/health?wait_for_events=...&timeout=...` will wait
indefinitely for the master to process the pending cluster health task,
ignoring the specified timeout. This could take a very long time if the master
is overloaded. This commit fixes this by adding a timeout to the pending
cluster health task.
Setting a slow log level requires an unnecessary conditional logic in SearchSlowLog and IndexingSlowLog
The behaviour of setting a level on a slow logger can be achieved with correct slow log threshold settings.
This PR is removing slow log and modifies tests to achieve the same behaviour with changing threshold.

Previously, hidden indices were not included in snapshots by default, unless
specified using one of the usual methods for doing so: naming indices directly,
using index patterns starting with a `.`, or specifying `expand_wildcards` to
a value that includes hidden (e.g. `all` or `hidden,open`).
This commit changes the default `expand_wildcards` value to include hidden
indices.
Prior to this commit, `cluster.max_shards_per_node` is not correctly handled
when it is set via the YAML config file, only when it is set via the Cluster
Settings API.
This commit refactors how the limit is implemented, both to enable correctly
handling the setting in the YAML and to more effectively centralize the logic
used to enforce the limit. The logic used to apply the limit, as well as the
setting value, has been moved to the new `ShardLimitValidator`.
This PR replaces the marker interface with the method
FieldMapper#parsesArrayValue. I find this cleaner and it will help with the
fields retrieval work (#55363).
The refactor also ensures that only field mappers can declare they parse array
values. Previously other types like ObjectMapper could implement the marker
interface and be passed array values, which doesn't make sense.
The test for `auto_date_histogram` as trying to round `Long.MAX_VALUE`
if there were 0 buckets. That doesn't work.
Also, this replaces all of the class variables created to make
consistent random result when testing `InternalAutoDateHistogram` with
the newer `randomResultsToReduce` which is a little simpler to
understand.
This PR adds a section to the new 'run a search' reference that explains
the options for returning fields. Previously each option was only listed as a
separate request parameter and it was hard to know what was available.
Previously, we had our own implementation for stripping leading and
trailing whitespaces which substantially less performant than the java's
String stripLeading & stripTrailingMethods.
Enhanced LENGTH unit tests and compine a couple of LTRIM/RTRIM integ
tests.
The test failed when it was running with 4 replicas and 3 indexing
threads. The recovering replicas can prevent the global checkpoint from
advancing. This commit increases the timeout to 60 seconds for this
suite and the check for no inflight requests.
Closes#57204

This commit updates the snapshot.delete.json REST API spec
to make snapshot a list type, now that it can accept a
list of comma-separated snapshot names
Currently we check that exceptions are the same in the recovery request
tracker test. This is inconsistent because the future wraps the
exception in a new instance. This commit fixes the test by comparing a
random exception message.
Fixes#57199
For a rolling/mixed cluster upgrade (add new version to existing cluster
then shutdown old instances), the watches that ship by default
with monitoring may not get properly updated to the new version.
Monitoring watches can only get published if the internal state is
marked as dirty. If a node is not master, will also get marked as
clean (e.g. not dirty).
For a mixed cluster upgrade, it is possible for the new node to be
added, not as master, the internal state gets marked as clean so
that no more attempts can be made to publish the watches. This
happens on all new nodes. Once the old nodes are de-commissioned
one of the new version nodes in the cluster gets promoted to master.
However, that new master node (with out intervention like restarting
the node or removing/adding exporters) will never attempt to re-publish
since the internal state was already marked as clean.
This commit adds a cluster state listener to mark the resource dirty
when a node is promoted to master. This will allow the new resource
to be published without any intervention.
