Clarify that searchable snapshots only result in cost savings for less
frequently accessed data and that the savings do not apply to the entire
cluster.
KeyStoreAwareCommand attempted to deduce whether an error occurred
because of a wrong password by checking the cause of the
SecurityException that KeyStoreWrapper.decrypt() throws. Checking
for AEADBadTagException was wrong becase that exception could be
(and usually is) wrapped in an IOException. Furthermore, since we
are doing the check already in KeyStoreWrapper, we can just return
the message of the SecurityException to the user directly, as we do
in other places.
Adjusted the README file to mention both the option to preserve the test
data when simple reproducing/executing the tests, but also when starting
the server node manually and issuing the query(ies) against it.

* Fix the `CombineBinaryComparisons` optimizer rule, so that semantic
equality taken into account during the optimization of `NotEquals`
Examples that previously removed the `NotEquals` expressions (leading
to incorrect results):
```
double >= 10 AND integer != 9
--> double >= 10
keyword != '2021' AND datetime >= '2020-01-01T00:00:00'
--> datetime >= '2020-01-01T00:00:00'
```
With the fix, expressions like the above will not be touched.
`NotEquals` will only be eliminated from the `AND` expression if the
left side of the `NotEquals` `semanticEquals()` to the left side
of the other expressions within the conjunction (comparisons against
the same field/expression).
* Unit tests and integration tests

Slack no longer recommends the legacy "integrations" setup (https://api.slack.com/legacy/custom-integrations/incoming-webhooks). Updated documentation to reference https://api.slack.com/messaging/webhooks instead.
Removed screenshots from our documentation related to Slack setup. We should avoid these screenshots (and simply point to Slack documentation) for Slack may change the instructions/their UI in the future.
Also added a short note on the use case of notifying multiple Slack channels.

In #65332, the serialization of the WatcherSearchTemplateRequest class
changed to use IndicesOptions built in XContent facilities. This had
the side effect of fixing the handling of `all` for `expand_wildcards`
to include hidden indices. However, the tests in WatcherUtilsTests were
missed. This change updates those tests.
Backport of #65379
A bug was introduced in 7.10 that causes explicit `null` values to be indexed in the _field_names
field. This change fixes this bug for newly ingested data but `null` values ingested with 7.10 will
continue to match `exists` query so a reindex is required.
Fixes#65306
This PR adds detail to the explanation of the soft_limit
memory_status in ML job stats. A consequence that was not
mentioned before is that examples are not added to category
definitions.
Relates elastic/ml-cpp#1590
This change fixes the equals and hashCode methods of the custom FieldValuesSource
that is used internally to extract the value from a doc value field.
Using the field data instance to check equality prevented the query to be cached in
previous versions. Switching to the field name should make the query eligible for
caching again.
Watcher has a search template that stores indices options to be used as
part of a search during watch execution, but this was not updated to be
aware of hidden indices and the `hidden` expand_wildcards option. This
change makes use of the `IndicesOptions#toXContent` method in Watcher,
which already handles the new value. Additionally, the XContent parsing
is moved to the IndicesOptions class so that we will be less likely to
miss updating this in the future.
Closes#65148

The _Important Elasticsearch configuration_ docs lists a number of items
that you should consider before moving to production. Today this list
does not include configuring snapshots, even though they're very
important to have in production. This commit addresses that omission,
removes some repetition from the introductory paragraphs, and notes that
this config is handled for you on Cloud.

The search-as-you-type mapper was using an incorrect default analyzer when
creating its merge builder, which meant that a configured analyzer would not
be included in serialization. This in turn resulted in the master node
getting an incorrect configuration, and search-as-you-type fields always
using a standard analyzer.
This has already been fixed via subsequent refactorings in 7.11 and master,
so this fix is for 7.10 only.
Resolves#65319
The recovery stats assertions in this test ran without any waiting for
the recoveries to actually finish. The fact that they ran after the concurrent
searches checks generally meant that they would pass (because of searches warming caches
+ general relative slowness of searches) but there is no hard guarantees this will work
reliably as the pre-fetch threads which will update the recovery state might still be slow
to do so randomly, causing the assertions to trip.
closes#65302
If we fail to create the `FileChannelReference` (e.g. because the directory it should be created in
was deleted in a test) we have to remove the listener from the `listeners` set to not trip internal
consistency assertions.
Relates #65302 (does not fix it though, but reduces noise from failures by removing secondary
tripped assertions after the test fails)
* Clarify that field data cache includes global ordinals
* Describe that the cache should be cleared once the limit is reached
* Clarify that the `_id` field does not supported aggregations anymore
* Fold the `fielddata` mapping parameter page into the `text field docs
* Improve cross-linking
This change fixes a bug where when doing compound assignment involving String concatenation, the
right-hand side will fail to cast to String appropriately and throw a ClassCastException.
In aa1ea96b8698aa12bed1c4e8d704882a2a639791 I made all
`testReduceRandom` tests for aggs mimick production more precisely.
More precisely, they pick the correct "lead" result when performing
partial reduction. This is great, but, sadly, some tests assumed that we
always reduced against the "first" aggregator. This fixes those tests.
Closes#65163
This changes has `InternalAggregationTestCase` performs partial
reductions to better mimick `InternalAggregations#reduce`. In
particular, this fixes a bug when we'd attempt a partial reduction of
aggregations that were entirely unmapped but use a mapped aggregation as
the "lead" of the reduction. This was possible in the test but isn't
possible in production. The reduction "lead" is unmapped if all agg
results being reduced are unmapped.
Closes#65118
Adds a `RestClient.setCompressionEnabled()` setting that will gzip-
compress request bodies and add a `Accept-Encoding: gzip` header so
that the ES server can send compressed responses.
This commit updates the IndexAbstractionResolver so that hidden indices
are properly resolved when date math is in use and when we are checking
if the index is visible.
Closes#65157
Backport of #65236
If a shard follow-task hits a non-retryable error and stops, then we
should also stop the retention-leases renewal process associated with
that follow-task.
This change fixes the initialization of the async results service
for the EQL get async action. The boolean that differentiates EQL
from normal _async_search request is set incorrectly, which results
in errors (404) when extending the keep alive of a running EQL search.
Fixes#65108
The current until implementation in sequences is too optimistic, leading
to an aggressive match that discards correct data leading to invalid
results.
This commit addresses this issue and also unifies the until usage inside
TumblingWindow.
Further more it packs together the UntilGroup with SequenceGroup to
minimize memory usage and improve clean-up.
