The change in #27500 introduces this regression that causes `_get` and `_term_vector`
actions to run on the network thread if the realtime flag is set.
This fixes the issue by delegating to the super method forking on the corresponding threadpool.
We use similar / same concepts in SerachTransportService and HandledTransportAction but both
duplicate the efforts with slightly different implementation details. This streamlines
sending responses / exceptions back to a channel in an ActionListener with appropriate logging.
Make sure that all java files have a package declaration and that all of
the package declarations line up with the directory structure. This
would have caught the bug that I caused in
190ea9a6de and fixed in
b6d68bd805.
The original statement "Runs a match_phrase query on each field and combines the _score from each field." for the phrase type is a but misleading. The phrase type behaves like the best_fields type and does not combine the scores of each fields.
In #33241 we moved the file-based discovery functionality to core
Elasticsearch, but preserved the `discovery-file` plugin, and support for the
existing location of the `unicast_hosts.txt` file, for BWC reasons. This commit
completes the removal of this plugin.
New plugin for annotated_text field type.
Largely a copy of `text` field type but adds ability to include markdown-like syntax in the text.
The “AnnotatedText” class parses text+markup and converts into plain text and AnnotationTokens.
The annotation token values are injected unchanged alongside the regular text tokens to provide a
form of additional indexed overlay useful in positional searches and highlighting.
Annotated_text fields do not support fielddata as we want to phase this out.
Also includes a new "annotated" highlighter type that retains annotations and merges in search
hits as additional annotation markup.
Closes#29467
Currently a watch execution results in one bulk request, when the
triggered watches are written into the that index, that need to be
executed. However the update of the watch status, the creation of the
watch history entry as well as the deletion of the triggered watches
index are all single document operations.
This can have quite a negative impact, once you are executing a lot of
watches, as each execution results in 4 documents writes, three of them
being single document actions.
This commit switches to a bulk processor instead of a single document
action for writing watch history entries and deleting triggered watch
entries. However the defaults are to run synchronous as before because
the number of concurrent requests is set to 0. This also fixes a bug,
where the deletion of the triggered watch entry was done asynchronously.
However if you have a high number of watches being executed, you can
configure watcher to delete the triggered watches entries as well as
writing the watch history entries via bulk requests.
The triggered watches deletions should still happen in a timely manner,
where as the history entries might actually be bound by size as one
entry can easily have 20kb.
The following settings have been added:
- xpack.watcher.bulk.actions (default 1)
- xpack.watcher.bulk.concurrent_requests (default 0)
- xpack.watcher.bulk.flush_interval (default 1s)
- xpack.watcher.bulk.size (default 1mb)
The drawback of this is of course, that on a node outage you might end
up with watch history entries not being written or watches needing to be
executing again because they have not been deleted from the triggered
watches index. The window of these two cases increases configuring the bulk processor to wait to reach certain thresholds.
The following stats are being kept track of:
1) The total number of times that auto following a leader index succeed.
2) The total number of times that auto following a leader index failed.
3) The total number of times that fetching a remote cluster state failed.
4) The most recent 256 auto follow failures per auto leader index
(e.g. create_and_follow api call fails) or cluster alias
(e.g. fetching remote cluster state fails).
Each auto follow run now produces a result that is being used to update
the stats being kept track of in AutoFollowCoordinator.

* MINOR: Drop Redundant Ctx. Check in ScriptService
* This check is completely redundant, the expression script
engine will throw anyway (and with a similar message) for
those contexts that it cannot compile. Moreover, the update context
is not the only context that is not suported by the expression engine
at this point so handling the update context separately here makes
no sense.

This PR removes fields that are not actually used by the Monitoring UI. This will greatly simplify the eventual migration to using Metricbeat for monitoring Elasticsearch (see https://github.com/elastic/beats/pull/8260#discussion_r215885868 for more context and discussion around removing these fields from ES collection).
This commit changes the sanity check which ensures the test task was
properly replaced with randomized testing to have a per project check,
isntead of a global one. The previous global check assumed all test
tasks within the root project and below should be randomized testing,
but that is not the case for a multi project in which only one project
is an elasticsearch plugin. While the new check is not able to emit all
of the failed replacements in one error message, the efficacy of the
check remains.

When a leader index is created, it may not have a mapping yet.
Currently if you follow such an index the shard follow tasks fail with
NoSuchElementException, because they expect a single mapping.
This commit fixes that, by allowing that a leader index does not yet have
a mapping.
We can't rely on the leaf reader ordinal in a wrapped reader since
it might not correspond to the ordinal in the SegmentInfos for it's
SegmentCommitInfo.

Allows to skip shard balancing when the cluster_concurrent_rebalance threshold is already reached, which cuts down the time spent in the rebalance method of BalancedShardsAllocator.
This commit adds the Create Rollup Job API to the high level REST
client. It supersedes #32703 and adds dedicated request/response
objects so that it does not depend on server side components.

Currently `IndexMetadata#getCustomData(...)` wraps the custom metadata
in an unmodifiable map, but in case there is no entry for the specified
key then a NPE is thrown by Collections.unmodifiableMap(...). This is not
ideal in case callers like to throw an exception with a specific message.
(like in the case for ccr to indicate that the follow index was not created
by the create_and_follow api and therefor incompatible as follow index)
I think making `DiffableStringMap` itself immutable is better then just wrapping
custom metadata with `Collections.unmodifiableMap(...)` in all methods that access it.
Also removed the `equals()`, `hashcode()` and to `toString()` methods of
`DiffableStringMap`, because `AbstractMap` already implements these methods.
This commit switches the joda time backcompat in scripting to use
augmentation over ZonedDateTime. The augmentation methods provide
compatibility with the missing methods between joda's DateTime and
java's ZonedDateTime. Due to getDayOfWeek returning an enum in the java
API, ZonedDateTime is wrapped so that the method can return int like the
joda time does. The java time api version is renamed to
getDayOfWeekEnum, which will be kept through 7.x for compatibility while
users switch back to getDayOfWeek once joda compatibility is removed.
This commit adds a guard around the rare case that no documents in the
10 iterations actually have any values, thus making the warning check
incorrect.
