This commit adds a new single value metric aggregation that calculates
the statistic called median absolute deviation, which is a measure of
variability that works on more types of data than standard deviation
Our calculation of MAD is approximated using t-digests. In the collect
phase, we collect each value visited into a t-digest. In the reduce
phase, we merge all value t-digests, then create a t-digest of
deviations using the first t-digest's median and centroids
This commit is our first introduction to cross-cluster replication
docs. In this commit, we introduce the cross-cluster replication API
docs. We also add skelton docs for additional content that will be added
in a series of follow-up commits.
These were disabled because ingest attachement was not playing well with
JDK 11. We have addressed that by upgrading the Tika dependency, yet
forgot to reenable these. This commit enables these tests again.
This commit switches to using a trial license in the docs tests that run
on the default distribution. This is needed so that docs tests can be
executed against non-basic features.
We'd disabled them because we didn't have a way to clean up after each
test. I implemented #34342 which adds the clean ups so now we can
re-enable the tests.
In the `setup` sections we have to use `raw` requests instead of
`x-pack` requests because we don't have the json config for x-pack.
Closes#33319
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.
* Scripted metric aggregations: add deprecation warning and system property to control legacy params
Scripted metric aggregation params._agg/_aggs are replaced by state/states context variables. By default the old params are still present, and a deprecation warning is emitted when Scripted Metric Aggregations are used. A new system property can be used to disable the legacy params. This functionality will be removed in a future revision.
* Fix minor style issue and docs test failure
* Disable deprecated params._agg/_aggs in tests and revise tests to use state/states instead
* Add integration test covering deprecated scripted metrics aggs params._agg/_aggs access
* Disable deprecated params._agg/_aggs in docs integration tests and revise stored scripts to use state/states instead
* Revert unnecessary migrations doc change
A relevant note should be added in the changes destined for 7.0; this PR is going to be backported to 6.x.
* Replace deprecated _agg param bwc integration test with a couple of unit tests
* Fix compatibility test after merge
* Rename backwards compatibility system property per code review feedback
* Tweak deprecation warning text per review feedback
This commit adds a boolean system property, `es.scripting.use_java_time`,
which controls the concrete return type used by doc values within
scripts. The return type of accessing doc values for a date field is
changed to Object, essentially duck typing the type to allow
co-existence during the transition from joda time to java time.
Adds a new single-value metrics aggregation that computes the weighted
average of numeric values that are extracted from the aggregated
documents. These values can be extracted from specific numeric
fields in the documents.
When calculating a regular average, each datapoint has an equal "weight"; it
contributes equally to the final value. In contrast, weighted averages
scale each datapoint differently. The amount that each datapoint contributes
to the final value is extracted from the document, or provided by a script.
As a formula, a weighted average is the `∑(value * weight) / ∑(weight)`
A regular average can be thought of as a weighted average where every value has
an implicit weight of `1`.

The range docs had an introductory section that described how to set up
and index *and* a test setup section in `docs/build.gradle` that
duplicated that section. This is bad because these section can (and do)
drift from one another. This change removes the setup in build.gradle
and marks the introductor snippet with `// TESTSETUP` so it is used on
all the snippets.
Skips tests the require xpack if we run the doc build without xpack. So
this should work:
```
./gradlew -p docs check -Dtests.distribution=oss-zip
```
This is implemented by detecting parts of the doc that look like:
```
[testenv="basic"]
```
Relates to #30665
This switches the docs tests from the `oss-zip` distribution to the
`zip` distribution so they have xpack installed and configured with the
default basic license. The goal is to be able to merge the
`x-pack/docs` directory into the `docs` directory, marking the x-pack
docs with some kind of marker. This is the first step in that process.
This also enables `-Dtests.distribution` support for the `docs`
directory so you can run the tests against the `oss-zip` distribution
with something like
```
./gradlew -p docs check -Dtests.distribution=oss-zip
```
We can set up Jenkins to run both.
Relates to #30665
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 change adds a new plugin called `analysis-nori` that exposes
Korean text analysis in es using the new Lucene Korean analyzer module named (`nori`).
The plugin adds:
* a Korean analyzer: `nori`
* a Korean tokenizer: `nori_tokenizer`
* a part of speech stop filter: `nori_part_of_speech`
* a filter that can replace Hanja characters with their Hangul transcription: `nori_readingform`
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
Allowing `_doc` as a type will enable users to make the transition to 7.0
smoother since the index APIs will be `PUT index/_doc/id` and `POST index/_doc`.
This also moves most of the documentation to `_doc` as a type name.
Closes#27750Closes#27751
Today we require users to prepare their indices for split operations.
Yet, we can do this automatically when an index is created which would
make the split feature a much more appealing option since it doesn't have
any 3rd party prerequisites anymore.
This change automatically sets the number of routinng shards such that
an index is guaranteed to be able to split once into twice as many shards.
The number of routing shards is scaled towards the default shard limit per index
such that indices with a smaller amount of shards can be split more often than
larger ones. For instance an index with 1 or 2 shards can be split 10x
(until it approaches 1024 shards) while an index created with 128 shards can only
be split 3x by a factor of 2. Please note this is just a default value and users
can still prepare their indices with `index.number_of_routing_shards` for custom
splitting.
NOTE: this change has an impact on the document distribution since we are changing
the hash space. Documents are still uniformly distributed across all shards but since
we are artificually changing the number of buckets in the consistent hashign space
document might be hashed into different shards compared to previous versions.
This is a 7.0 only change.
Today Cross Cluster Search requires at least one node in each remote cluster to be up once the cross cluster search is run. Otherwise the whole search request fails despite some of the data (either local and/or remote) is available. This happens when performing the _search/shards calls to find out which remote shards the query has to be executed on. This scenario is different from shard failures that may happen later on when the query is actually executed, in case e.g. remote shards are missing, which is not going to fail the whole request but rather yield partial results, and the _shards section in the response will indicate that.
This commit introduces a boolean setting per cluster called search.remote.$cluster_alias.skip_if_disconnected, set to false by default, which allows to skip certain clusters if they are down when trying to reach them through a cross cluster search requests. By default all clusters are mandatory.
Scroll requests support such setting too when they are first initiated (first search request with scroll parameter), but subsequent scroll rounds (_search/scroll endpoint) will fail if some of the remote clusters went down meanwhile.
The search API response contains now a new _clusters section, similar to the _shards section, that gets returned whenever one or more clusters were disconnected and got skipped:
"_clusters" : {
"total" : 3,
"successful" : 2,
"skipped" : 1
}
Such section won't be part of the response if no clusters have been skipped.
The per cluster skip_unavailable setting value has also been added to the output of the remote/info API.
The current script service has a script compilation limit for a one
minute window. This is set to a small default value of 15. Instead of
increasing that default value, this commit introduces a new setting
that allows to configure a rate per time unit, so that the script service can deal with bursts better.
The new setting is named `script.max_compilations_rate`,
requires a nonnegative number and a positive time value.
The default is `75/5m`, which is equivalent to the existing 15 per minute.
* Migrate migration docs from 6.0 to 7.0
Since we only keep one version of migration docs and master is now on 7.0, we
should migrate these so breaking changes can be added in the right place.
* Remove release notes as well
They link to the migration guides, so they have to go.
* Add placeholder notes for 7.0 so doc build is happy
This commit adds back "id" as the key within a script to specify a
stored script (which with file scripts now gone is no longer ambiguous).
It also adds "source" as a replacement for "code". This is in an attempt
to normalize how scripts are specified across both put stored scripts and script usages, including search template requests. This also deprecates the old inline/stored keys.
* Adds nodes usage API to monitor usages of actions
The nodes usage API has 2 main endpoints
/_nodes/usage and /_nodes/{nodeIds}/usage return the usage statistics
for all nodes and the specified node(s) respectively.
At the moment only one type of usage statistics is available, the REST
actions usage. This records the number of times each REST action class is
called and when the nodes usage api is called will return a map of rest
action class name to long representing the number of times each of the action
classes has been called.
Still to do:
* [x] Create usage service to store usage statistics
* [x] Record usage in REST layer
* [x] Add Transport Actions
* [x] Add REST Actions
* [x] Tests
* [x] Documentation
* Rafactors UsageService so counts are done by the handlers
* Fixing up docs tests
* Adds a name to all rest actions
* Addresses review comments
