This pipeline aggregation gives the user the ability to script functions that "move" across a window
of data, instead of single data points. It is the scripted version of MovingAvg pipeline agg.
Through custom script contexts, we expose a number of convenience methods:
- MovingFunctions.max()
- MovingFunctions.min()
- MovingFunctions.sum()
- MovingFunctions.unweightedAvg()
- MovingFunctions.linearWeightedAvg()
- MovingFunctions.ewma()
- MovingFunctions.holt()
- MovingFunctions.holtWinters()
- MovingFunctions.stdDev()
The user can also define any arbitrary logic via their own scripting, or combine with the above methods.
This change adds a `listTasks` method to the high level java
ClusterClient which allows listing running tasks through the
task management API.

This commit adds Create Repository, the associated docs and tests
for the high level REST API client. A few small changes to the
PutRepository Request and Response went into the commit as well.
This commit exposes the master version to the REST test context. This
will be needed in a follow-up where the master version will be used to
determine whether or not a certain warning header is expected.
This does away with the deprecated `com.google.api-client:google-api-client:1.23`
and replaces it with `com.google.cloud:google-cloud-storage:1.28.0`.
It also changes security permissions for the repository-gcs plugin.
We are starting over on the changelog with a different approach. This
commit removes the existing incarnation of the changelog to remove
confusion that we need to continue adding entries to it.
The geo_bounding_box query might produce false positives alongside
the right and upper edges and false negatives alongside left and
bottom edges. This commit documents the behavior and defines the
maximum error.
Closes#29196
This commit changes the default out-of-the-box configuration for the
number of shards from five to one. We think this will help address a
common problem of oversharding. For users with time-based indices that
need a different default, this can be managed with index templates. For
users with non-time-based indices that find they need to re-shard with
the split API in place they no longer need to resort only to
reindexing.
Since this has the impact of changing the default number of shards used
in REST tests, we want to ensure that we still have coverage for issues
that could arise from multiple shards. As such, we randomize (rarely)
the default number of shards in REST tests to two. This is managed via a
global index template. However, some tests check the templates that are
in the cluster state during the test. Since this template is randomly
there, we need a way for tests to skip adding the template used to set
the number of shards to two. For this we add the default_shards feature
skip. To avoid having to write our docs in a complicated way because
sometimes they might be behind one shard, and sometimes they might be
behind two shards we apply the default_shards feature skip to all docs
tests. That is, these tests will always run with the default number of
shards (one).
The High Level REST Client's documentation suggested that users should
use the Low Level REST Client for index management activities. This
change removes that suggestion because the high level REST client
supports those APIs now.
This also changes the examples in the migration docs to that still use
the Low Level REST Client to use the non-deprecated varieats of
`performRequest`.
We want copying settings to be the default behavior. This commit
deprecates not copying settings, and disallows explicitly not copying
settings. This gives users a transition path to the future default
behavior.
Dates internally contain milliseconds (which appear when converting them
to Strings) however parsing does not accept them (and is being strict).
The parser has been changed so that Date is mandatory but the time
(including its fractions such as millis) are optional.
Fix#30002
We have a pile of documentation describing how to rebuild the built in
language analyzers and, previously, our documentation testing framework
made sure that the examples successfully built *an* analyzer but they
didn't assert that the analyzer built by the documentation matches the
built in anlayzer. Unsuprisingly, some of the examples aren't quite
right.
This adds a mechanism that tests that the analyzers built by the docs.
The mechanism is fairly simple and brutal but it seems to be working:
build a hundred random unicode sequences and send them through the
`_analyze` API with the rebuilt analyzer and then again through the
built in analyzer. Then make sure both APIs return the same results.
Each of these calls to `_anlayze` takes about 20ms on my laptop which
seems fine.
This commit adds the Snapshot Client with a first API call within it,
the get repositories call in snapshot/restore module. This also creates
a snapshot namespace for the docs, as well as get repositories docs.
Relates #27205
Today we can execute cluster API actions on only master, data or ingest nodes
using the `master:true`, `data:true` and `ingest:true` filters, but it is not
so easy to select coordinating-only nodes (i.e. those nodes that are neither
master nor data nor ingest nodes). This change fixes this by adding support for
a `coordinating_only` filter such that `coordinating_only:true` adds all
coordinating-only nodes to the set of selected nodes, and
`coordinating_only:false` deletes them.
Resolves#28831.
The HTTPClient used in watcher is based on the apache http client. The
current client is using a lot of defaults - which are not always
optimal. Two of those defaults are the maximum number of total
connections and the maximum number of connections to a single route.
If one of those limits is reached, the HTTPClient waits for a connection
to be finished thus acting in a blocking fashion. In order to prevent
this when many requests are being executed, we increase the limit of
total connections as well as the connections per route (a route is
basically an endpoint, which also contains proxy information, not
containing an URL, just hosts).
On top of that an additional option has been set to evict
long running connections, which can potentially be reused after some
time. As this requires an additional background thread, this required
some changes to ensure that the httpclient is closed properly. Also the
timeout for this can be configured.
Deprecate the many arguments versions of `performRequest` and
`performRequestAsync` in favor of the `Request` object flavored variants
introduced in #29623. We'll be dropping the many arguments variants in
7.0 because they make it difficult to add new features in a backwards
compatible way and they create a *ton* of intellisense noise.
We had been using `task_id:1` or `taskId:1` because it is parses as a
valid task identifier but the `:1` part is confusing. This replaces
those examples with `task_id` which matches the response from the list
tasks API.
Closes#28314
Fixes and edge case when using `more_like_this` where TermVectorsWriter
could throw an NPE when a field produced zero tokens after analysis. This
changes the implementation to use an empty list of tokens in this case.
Closes#30148
Auto-expands replicas in the same cluster state update (instead of a follow-up reroute) where nodes are added or removed.
Closes#1873, fixing an issue where nodes drop their copy of auto-expanded data when coming up, only to sync it again later.
Adds verification that geohashes are not empty and contain only
valid characters. It fixes the issue when en empty geohash is
treated as [-180, -90] and geohashes with non-geohash character
are getting resolved into invalid coordinates.
Closes#23579
When deleting or creating a snapshot for a given shard, elasticsearch
usually starts by listing all the existing snapshotted files in the repository.
Then it computes a diff and deletes the snapshotted files that are not
needed anymore. During this deletion, an exception is thrown if the file
to be deleted does not exist anymore.
This behavior is challenging with cloud based repository implementations
like S3 where a file that has been deleted can still appear in the bucket for
few seconds/minutes (because the deletion can take some time to be fully
replicated on S3). If the deleted file appears in the listing of files, then the
following deletion will fail with a NoSuchFileException and the snapshot
will be partially created/deleted.
This pull request makes the deletion of these files a bit less strict, ie not
failing if the file we want to delete does not exist anymore. It introduces a
new BlobContainer.deleteIgnoringIfNotExists() method that can be used
at some specific places where not failing when deleting a file is
considered harmless.
