increases the scheduler interval to fire less frequently, namely changing it from 1s to 10s. The scheduler interval is used for retrying after an error condition.
Adds a metadata field to snapshots which can be used to store arbitrary
key-value information. This may be useful for attaching a description of
why a snapshot was taken, tagging snapshots to make categorization
easier, or identifying the source of automatically-created snapshots.
The `replace` option in the phonetic token filter can have suprising side
effects, e.g. such as described in #26921. This PR adds a note to be mindful
about such scenarios and offers alternatives to using the `replace` option.

Some clusters might have been already migrated to version 7 without being warned about the joda-java migration changes.
Deprecation api on that version will give them guidance on what patterns need to be changed.
relates. This change is using the same logic like in 6.8 that is: verifying the pattern is from the incompatible set ('y'-Y', 'C', 'Z' etc), not from predifined set, not prefixed with 8. AND was also created in 6.x. Mappings created in 7.x are considered migrated and should not generate warnings
There is no pipeline check (present on 6.8) as it is impossible to verify when the pipeline was created, and therefore to make sure the format is depracated or not

This change abstracts the specific types away from the different
representations of datetime as a datetime representation in code can be all
kinds of different things. This defines the three most common types of
datetimes as numeric, string, and complex while outlining the type most
typically used for these as long, String, and ZonedDateTime, respectively.
Documentation uses the definitions while examples use the types. This makes
the documentation easier to consume especially for people from a non-Java
background.

This commit disables building on JDK 13 in CI. The reason for this is
because Gradle is not yet ready to run on JDK 13. We could re-introduce
infrastructure to enable Gralde to run on a different JDK than the build
JDK, but rather than introducing such complexity we will instead wait
for Gradle to be ready to run on JDK 13.
Dots in the column names cause an error in the ingest
pipeline, as dots are special characters in ingest pipeline.
This PR changes dots into underscores in CSV field names
suggested by the ML find_file_structure endpoint _unless_
the field names are specifically overridden. The reason for
allowing them in overrides is that fields that are not
mentioned in the ingest pipeline can contain dots. But it's
more consistent that the default behaviour is to replace
them all.

The full-text query parsers accept field pattern that are expanded using the mapping.
Alias field are also detected during the expansion but they are not deduplicated with the
concrete fields that are found from other patterns (or the same). This change ensures
that we deduplicate the target fields of the full-text query parsers in order to avoid
adding the same clause multiple times. Boolean queries are already able to deduplicate
clauses during rewrite but since we also use DisjunctionMaxQuery it is preferable to detect
these duplicates early on.
This change makes use of the reader attributes added in LUCENE-8671
to ensure that `_id` fields are always on-heap for best update performance
and term dicts are generally off-heap on Read-Only engines.

This test is failing because recoveries of these empty shards are not
completing in a reasonable time, but the reason for this is still obscure. This
commit adds yet more logging.

This commit adds functionality so that aliases that are manipulated on
leader indices are replicated by the shard follow tasks to the follower
indices. Note that we ignore write indices. This is due to the fact that
follower indices do not receive direct writes so the concept is not
useful.

This commit fixes the version parsing in various tests. The issue here is that
the parsing was relying on java.version. However, java.version can contain
additional characters such as -ea for early access builds. See JEP 233:
Name Syntax
------------------------------ --------------
java.version $VNUM(\-$PRE)?
java.runtime.version $VSTR
java.vm.version $VSTR
java.specification.version $VNUM
java.vm.specification.version $VNUM
Instead, we want java.specification.version.
This commit performs the proper restore of network disruption.
Previously disruptionScheme.stopDisrupting() was called that does not
ensure that connectivity between cluster nodes is restored. The test
was checking that the cluster has green status, but it was not checking
that connectivity between nodes is restored.
Here we switch to internalCluster().clearDisruptionScheme(true) which
performs both checks before returning.

The control flow in TransportAnalyzeAction is currently spread across two large
methods, and is quite difficult to follow. This commit tidies things up a bit, to make
it clearer when we use pre-defined analyzers and when we use custom built ones.
Adding notes to the existing docs about how using `preference` might increase
request cache utilization but also add warning about the downsides.

This commit adds a configuration guide for the newly introduced
OpenID Connect realm. The guide is similar to the style of the
SAML Guide and shares certain parts where applicable (role mapping)
It also contains a short section on how the realm can be used for
authenticating users without Kibana.

Backport of #41423 and #42555
This commit removes the TLS cluster join validator.
This validator existed to prevent v6.x nodes (which mandated
TLS) from joining an existing cluster of v5.x nodes (which did
not mandate TLS) unless the 6.x node (and by implication the
5.x nodes) was configured to use TLS.
Since 7.x nodes cannot talk to 5.x nodes, this validator is no longer
needed.
Removing the validator solves a problem where single node clusters
that were bound to local interfaces were incorrectly requiring TLS
when they recovered cluster state and joined their own cluster.

This commit addresses a few more frequently-asked questions:
* clarifies that bootstrapping doesn't happen even after a full cluster
restart.
* removes the example that uses IP addresses, to try and further encourage the
use of node names for bootstrapping.
* clarifies that auto-bootstrapping might form different clusters on different
hosts, and gives a process for starting again if this wasn't what you wanted.
* adds the "do not stop half-or-more of the master-eligible nodes" slogan that
was notably absent.
* reformats one of the console examples to a narrower width
Whether security is enabled/disabled is dependent on the combination
of the node settings and the cluster license.
This commit adds a license state listener that logs when the license
change causes security to switch state (or to be initialised).
This is primarily useful for diagnosing cluster formation issues.
Backport of: #42488
If the security index is closed, it should be treated as unavailable
for security purposes.
Prior to 8.0 (or in a mixed cluster) a closed security index has
no routing data, which would cause a NPE in the cluster change
handler, and the index state would not be updated correctly.
This commit fixes that problem

(cherry picked from commit 4e0c6525153b60a57202937c2ae57968c8e35285)
When analysing a semi-structured text file the
find_file_structure endpoint merges lines to form
multi-line messages using the assumption that the
first line in each message contains the timestamp.
However, if the timestamp is misdetected then this
can lead to excessive numbers of lines being merged
to form massive messages.
This commit adds a line_merge_size_limit setting
(default 10000 characters) that halts the analysis
if a message bigger than this is created. This
prevents significant CPU time being spent subsequently
trying to determine the internal structure of the
huge bogus messages.
