Hendrik Muhs a70389015d [Transform] Return parsed count for get transform stats (#62809)
In case of more than 500 transforms, get and stats return paged results which can be requested using
page parameters. For >500 transforms count wasn't parsed out of the server response but taken from
size of the list of transforms.

The change also adds client/server hlrc tests and fixes a wrong type for count in get.

fixes #56245

EQL: Remove support for `=` for comparisons (#62756) (#62775)
Since `=` is rarely used and is undocumented we its support for
equality comparisons keeping `==` as the only option. `=` is now only
used for assignments like in `maxspan=10m`.

* [ML] Add new include flag to GET inference/<model_id> API for model training metadata (#61922)

Adds new flag include to the get trained models API
The flag initially has two valid values: definition, total_feature_importance.
Consequently, the old include_model_definition flag is now deprecated.
When total_feature_importance is included, the total_feature_importance field is included in the model metadata object.
Including definition is the same as previously setting include_model_definition=true.

* fixing test

* Update x-pack/plugin/core/src/test/java/org/elasticsearch/xpack/core/ml/action/GetTrainedModelsRequestTests.java

[7.x] ILM migrate data between tiers (#61377) (#62536)
This adds ILM support for automatically migrating the managed
indices between data tiers.

This proposal makes use of a MigrateAction that is injected
(similar to how the Unfollow action is injected) in phases that
don't define index allocation rules using the AllocateAction or
don't explicitly define the MigrateAction itself (regardless if it's
enabled or disabled).

[7.x] Remove integTest task from PluginBuildPlugin (#61879) (#62135)
This commit removes `integTest` task from all es-plugins.  
Most relevant projects have been converted to use yamlRestTest, javaRestTest, 
or internalClusterTest in prior PRs. 

A few projects needed to be adjusted to allow complete removal of this task
* x-pack/plugin - converted to use yamlRestTest and javaRestTest 
* plugins/repository-hdfs - kept the integTest task, but use `rest-test` plugin to define the task
* qa/die-with-dignity - convert to javaRestTest
* x-pack/qa/security-example-spi-extension - convert to javaRestTest
* multiple projects - remove the integTest.enabled = false (yay!)

Drop assertion that rest client header warnings conform to RFC 7234 (#61365) (#61799)
This removes the assertion that the header warnings we parse in the
rest client reponses conform to RFC 7234	because we are not in full control
of the warnings that could be present in the responses (ie. proxies might
emit warnings that don't comply).

We still maintain this assertion on the ES side (see `HeaderWarning#addWarning`)
for the warnings we emit.

Do not create two loggers for DeprecationLogger backport(#58435) (#61530)
DeprecationLogger's constructor should not create two loggers. It was
taking parent logger instance, changing its name with a .deprecation
prefix and creating a new logger.
Most of the time parent logger was not needed. It was causing Log4j to

EQL: Replace SearchHit in response with Event (#61428) (#61522)
The building block of the eql response is currently the SearchHit. This
is a problem since it is tied to an actual search, and thus has scoring,
highlighting, shard information and a lot of other things that are not
relevant for EQL.
This becomes a problem when doing sequence queries since the response is
not generated from one search query and thus there are no SearchHits to
speak of.
Emulating one is not just conceptually incorrect but also problematic
since most of the data is missed or made-up.

As such this PR introduces a simple class, Event, that maps nicely to
the terminology while hiding the ES internals (the use of SearchHit or
GetResult/GetResponse depending on the API used).

Simplify and Speed up some Compression Usage (#60953) (#61008)
Use thread-local buffers and deflater and inflater instances to speed up
compressing and decompressing from in-memory bytes.
Not manually invoking `end()` on these should be safe since their off-heap memory
will eventually be reclaimed by the finalizer thread which should not be an issue for thread-locals
that are not instantiated at a high frequency.
This significantly reduces the amount of byte copying and object creation relative to the previous approach
which had to create a fresh temporary buffer (that was then resized multiple times during operations), copied
bytes out of that buffer to a freshly allocated `byte[]`, used 4k stream buffers needlessly when working with
bytes that are already in arrays (`writeTo` handles efficient writing to the compression logic now) etc.

Relates #57284 which should be helped by this change to some degree.
Also, I expect this change to speed up mapping/template updates a little as those make heavy use of these
code paths.

[7.x] Adding new `require_alias` option to indexing requests (#58917) (#59769)
* Adding new `require_alias` option to indexing requests (#58917)

This commit adds the `require_alias` flag to requests that create new documents.

This flag, when `true` prevents the request from automatically creating an index. Instead, the destination of the request MUST be an alias.

When the flag is not set, or `false`, the behavior defaults to the `action.auto_create_index` settings.

This is useful when an alias is required instead of a concrete index.

* [ML] add new `custom` field to trained model processors (#59542)

This commit adds the new configurable field `custom`.

`custom` indicates if the preprocessor was submitted by a user or automatically created by the analytics job.

Eventually, this field will be used in calculating feature importance. When `custom` is true, the feature importance for
the processed fields is calculated. When `false` the current behavior is the same (we calculate the importance for the originating field/feature).

This also adds new required methods to the preprocessor interface. If users are to supply their own preprocessors
in the analytics job configuration, we need to know the input and output field names.

[7.x][ML] Data frame analytics max_num_threads setting (#59254) (#59308)
This adds a setting to data frame analytics jobs called
`max_number_threads`. The setting expects a positive integer.
When used the user specifies the max number of threads that may
be used by the analysis. Note that the actual number of threads
used is limited by the number of processors on the node where
the job is assigned. Also, the process may use a couple more threads
for operational functionality that is not the analysis itself.

This setting may also be updated for a stopped job.

More threads may reduce the time it takes to complete the job at the cost
of using more CPU.

Fix the timestamp field of a data stream to @timestamp (#59210)
Backport of #59076 to 7.x branch.

The commit makes the following changes:
* The timestamp field of a data stream definition in a composable
  index template can only be set to '@timestamp'.
* Removed custom data stream timestamp field validation and reuse the validation from `TimestampFieldMapper` and
  instead only check that the _timestamp field mapping has been defined on a backing index of a data stream.
* Moved code that injects _timestamp meta field mapping from `MetadataCreateIndexService#applyCreateIndexRequestWithV2Template58956(...)` method
  to `MetadataIndexTemplateService#collectMappings(...)` method.
* Fixed a bug (#58956) that cases timestamp field validation to be performed
  for each template and instead of the final mappings that is created.
* only apply _timestamp meta field if index is created as part of a data stream or data stream rollover,
this fixes a docs test, where a regular index creation matches (logs-*) with a template with a data stream definition.

Restoring a data stream from a snapshot could install a data stream that
doesn't match any composable templates. This also makes the `template`

Costin Leau f9c15d0fec EQL: Introduce sequencing fetch size (#59063)
The current internal sequence algorithm relies on fetching multiple results and then paginating through the dataset. Depending on the dataset and memory, setting a larger page size can yield better performance at the expense of memory.
This PR makes this behavior explicit by decoupling the fetch size from size, the maximum number of results desired.
As such, use in testing a minimum fetch size which exposed a number of bugs:

Jumping across data across queries causing valid data to be seen as a gap.
Incorrectly resuming searching across pages (again causing data to be discarded).

Add index block api (#58716)
Adds an API for putting an index block in place, which also ensures for write blocks that, once successfully returning to
the user, all shards of the index are properly accounting for the block, for example that all in-flight writes to an index have
been completed after adding the write block.

This API allows coordinating more complex workflows, where it is crucial that an index is no longer receiving writes after
the API completes, useful for example when marking an index as read-only during an upgrade in order to reindex its
documents.

Add Variable Width Histogram Aggregation (backport of #42035) (#58440)
Implements a new histogram aggregation called `variable_width_histogram` which
dynamically determines bucket intervals based on document groupings. These
groups are determined by running a one-pass clustering algorithm on each shard
and then reducing each shard's clusters using an agglomerative
clustering algorithm.

This PR addresses #9572.

The shard-level clustering is done in one pass to minimize memory overhead. The
algorithm was lightly inspired by
[this paper](https://ieeexplore.ieee.org/abstract/document/1198387). It fetches
a small number of documents to sample the data and determine initial clusters.
Subsequent documents are then placed into one of these clusters, or a new one
if they are an outlier. This algorithm is described in more details in the
aggregation's docs.

At reduce time, a
[hierarchical agglomerative clustering](https://en.wikipedia.org/wiki/Hierarchical_clustering)
algorithm inspired by [this paper](https://arxiv.org/abs/1802.00304)
continually merges the closest buckets from all shards (based on their
centroids) until the target number of buckets is reached.

The final values produced by this aggregation are approximate. Each bucket's
min value is used as its key in the histogram. Furthermore, buckets are merged
based on their centroids and not their bounds. So it is possible that adjacent
buckets will overlap after reduction. Because each bucket's key is its min,
this overlap is not shown in the final histogram. However, when such overlap
occurs, we set the key of the bucket with the larger centroid to the midpoint
between its minimum and the smaller bucket’s maximum:
`min[large] = (min[large] + max[small]) / 2`. This heuristic is expected to
increases the accuracy of the clustering.

Nodes are unable to share centroids during the shard-level clustering phase. In
the future, resolving https://github.com/elastic/elasticsearch/issues/50863
would let us solve this issue.

It doesn’t make sense for this aggregation to support the `min_doc_count`
parameter, since clusters are determined dynamically. The `order` parameter is
not supported here to keep this large PR from becoming too complex.

Allow follower indices to override leader settings (#58103)
Today when creating a follower index via the put follow API, or via an
auto-follow pattern, it is not possible to specify settings overrides
for the follower index. Instead, we copy all of the leader index
settings to the follower. Yet, there are cases where a user would want
some different settings on the follower index such as the number of
replicas, or allocation settings. This commit addresses this by allowing
the user to specify settings overrides when creating follower index via
manual put follower calls, or via auto-follow patterns. Note that not
all settings can be overrode (e.g., index.number_of_shards) so we also
have detection that prevents attempting to override settings that must
be equal between the leader and follow index. Note that we do not even
allow specifying such settings in the overrides, even if they are
specified to be equal between the leader and the follower
index. Instead, the must be implicitly copied from the leader index, not
explicitly set by the user.

Allow index filtering in field capabilities API (#57276) (#58299)
This change allows to use an `index_filter` in the
field capabilities API. Indices are filtered from
the response if the provided query rewrites to `match_none`
on every shard:

````
GET metrics-*
{
  "index_filter": {
    "bool": {
      "must": [
        "range": {
          "@timestamp": {
            "gt": "2019"
          }
        }
      }
  }
}
````

The filtering is done on a best-effort basis, it uses the can match phase
to rewrite queries to `match_none` instead of fully executing the request.
The first shard that can match the filter is used to create the field
capabilities response for the entire index.

[7.x][ML] Fix race condition when force stopping DF analytics job (#57680) (#57717)
When we force delete a DF analytics job, we currently first force
stop it and then we proceed with deleting the job config.
This may result in logging errors if the job config is deleted
before it is retrieved while the job is starting.

Instead of force stopping the job, it would make more sense to
try to stop the job gracefully first. So we now try that out first.
If normal stop fails, then we resort to force stopping the job to
ensure we can go through with the delete.

In addition, this commit introduces `timeout` for the delete action
and makes use of it in the child requests.

the steps to be able to identify when a managed index is part of a DataStream.

If a managed index is part of a DataStream the rollover target is the DataStream
name and the highest generation index is the write index (ie. the rolled index).

This adds a max_model_memory setting to forecast requests.

The default value is `20mb`.

There is a HARD limit at `500mb` which will throw an error if used.

If the limit is larger than 40% the anomaly job's configured model limit, the forecast limit is reduced to be strictly lower than that value. This reduction is logged and audited.

[ML] relax throttling on expired data cleanup (#56711) (#56895)
Throttling nightly cleanup as much as we do has been over cautious.

Night cleanup should be more lenient in its throttling. We still
keep the same batch size, but now the requests per second scale
with the number of data nodes. If we have more than 5 data nodes,
we don't throttle at all.

Additionally, the API now has `requests_per_second` and `timeout` set.
So users calling the API directly can set the throttling.

This commit also adds a new setting `xpack.ml.nightly_maintenance_requests_per_second`.
This will allow users to adjust throttling of the nightly maintenance.

[7.x] Add simulate template composition API _index_template/_simulate_index/{name} (#55686) (#55922)
This adds a new api to simulate matching the given index name against the
 index templates in the system.

The syntax for the new API takes the following form:

POST _index_template/_simulate_index/{index_name}
{
  "index_patterns": ["logs-*"],
  "priority": 15,
  "template": {
	"settings": {
		"number_of_shards": 3
	}
       ...
   }
}

Where the body is optional, but we support the entire body used by the
PUT _index_template/{name} api. When the body is specified we'll simulate
matching the given index against a system that'd have the given index
template together with the index templates that exist in the system.

The response, in both cases, will return the matching template's resolved
settings, mappings and aliases, together with a special field that'll print any
overlapping templates and their corresponding index patterns.

Adds a "node" field to the response from the following endpoints:

1. Open anomaly detection job
2. Start datafeed
3. Start data frame analytics job

If the job or datafeed is assigned to a node immediately then
this field will return the ID of that node.

In the case where a job or datafeed is opened or started lazily
the node field will contain an empty string.  Clients that want
to test whether a job or datafeed was opened or started lazily
can therefore check for this.

[7.x] Add prefer_v2_templates flag and index setting (#55411) (#55476)
This commit adds a new querystring parameter on the following APIs:
- Index
- Update
- Bulk
- Create Index
- Rollover

These APIs now support a `?prefer_v2_templates=true|false` flag. This flag changes the preference
creation to use either V2 index templates or V1 templates. This flag defaults to `false` and will be
changed to `true` for 8.0+ in subsequent work.

Additionally, setting this flag internally sets the `index.prefer_v2_templates` index-level setting.
This setting is used so that actions that automatically create a new index (things like rollover
initiated by ILM) will inherit the preference from the original index. This setting is dynamic so
that a transition from v1 to v2 templates can occur for long-running indices grouped by an alias
performing periodic rollover.

This also adds support for sending this parameter to the High Level Rest Client.

Make data streams in APIs resolvable. (#55337)
Backport from: #54726

The INCLUDE_DATA_STREAMS indices option controls whether data streams can be resolved in an api for both concrete names and wildcard expressions. If data streams cannot be resolved then a 400 error is returned indicating that data streams cannot be used.

In this pr, the INCLUDE_DATA_STREAMS indices option is enabled in the following APIs: search, msearch, refresh, index (op_type create only) and bulk (index requests with op type create only). In a subsequent later change, we will determine which other APIs need to be able to resolve data streams and enable the INCLUDE_DATA_STREAMS indices option for these APIs.

Whether an api resolve all backing indices of a data stream or the latest index of a data stream (write index) depends on the IndexNameExpressionResolver.Context.isResolveToWriteIndex().
If isResolveToWriteIndex() returns true then data streams resolve to the latest index (for example: index api) and otherwise a data stream resolves to all backing indices of a data stream (for example: search api).

* Wire Cardinality aggregation to work with the ValuesSourceRegistry (#51337)

* Wire Percentiles aggregator into new VS framework (#51639)

This required a bit of a refactor to percentiles itself.  Before,
the Builder would switch on the chosen algo to generate an
algo-specific factory.  This doesn't work (or at least, would be
difficult) in the new VS framework.

This refactor consolidates both factories together and introduces
a PercentilesConfig object to act as a standardized way to pass
algo-specific parameters through the factory.  This object
is then used when deciding which kind of aggregator to create

Note: CoreValuesSourceType.HISTOGRAM still lives in core, and will
be moved in a subsequent PR.

- Introduces a new API (`getBareAggregatorRegistrar()`) which allows plugins to register aggregations against existing agg definitions defined in Core.
- This moves the histogram VSType over to XPack where it belongs. `getHistogramValues()` still remains as a Core concept
- Moves the histo-specific bits over to xpack (e.g. the actual aggregator logic). This requires extra boilerplate since we need to create a new "Analytics" Percentile/Rank aggregators to deal with the histo field. Doubly-so since percentiles/ranks are extra boiler-plate'y... should be much lighter for other aggs

[7.x] Fix responses for the token APIs (#54532) (#55278)
This commit fixes our behavior regarding the responses we
return in various cases for the use of token related APIs.
More concretely:

- In the Get Token API with the `refresh` grant, when an invalid
(already deleted, malformed, unknown) refresh token is used in the
body of the request, we respond with `400` HTTP status code
 and an `error_description` header with the message "could not
refresh the requested token".
Previously we would return erroneously return a  `401` with "token
malformed" message.

- In the Invalidate Token API, when using an invalid (already
deleted, malformed, unknown) access or refresh token, we respond
with `404` and a body that shows that no tokens were invalidated:
   ```
   {
     "invalidated_tokens":0,
     "previously_invalidated_tokens":0,
      "error_count":0
   }
   ```
   The previous behavior would be to erroneously return
a `400` or `401` ( depending on the case ).

- In the Invalidate Token API, when the tokens index doesn't
exist or is closed, we return `400` because we assume this is
a user issue either because they tried to invalidate a token
when there is no tokens index yet ( i.e. no tokens have
been created yet or the tokens index has been deleted ) or the
index is closed.

- In the Invalidate Token API, when the tokens index is
unavailable, we return a `503` status code because
we want to signal to the caller of the API that the token they
tried to invalidate was not invalidated and we can't be sure
if it is still valid or not, and that they should try the request
again.

David Roberts 8c33cad2b2 [TEST] Lower ML model memory limit in HLRC datafeed tests (#55210)
The MachineLearningIT.testStopDatafeed test was creating 3
jobs each with the default model memory limit of 1GB.  This
meant that the test would not run on a machine with less than
10GB of RAM (due to the default ML memory percentage of 30%).

This change reduces the model memory limit for these jobs to
0.5GB, which means the test will run on a machine with only
5GB of RAM.

Clean up how pipeline aggs check for multi-bucket (backport of #54161) (#54379)
Pipeline aggregations like `stats_bucket`, `sum_bucket`, and
`percentiles_bucket` only operate on buckets that have multiple buckets.
This adds support for those aggregations to `geo_distance`, `ip_range`,
`auto_date_histogram`, and `rare_terms`.

This all happened because we used a marker interface to mark compatible
aggs, `MultiBucketAggregationBuilder` and it was fairly easy to forget
to implement the interface.

This replaces the marker interface with an abstract method in
`AggregationBuilder`, `bucketCardinality` which makes you return `NONE`,
`ONE`, or `MANY`. The `bucket` aggregations can check for `MANY`. At
this point `ONE` and `NONE` amount to about the same thing, but I
suspect that'll be a useful distinction when validating bucket sorts.

HLRC: Don't send defaults for SubmitAsyncSearchRequest (#54200) (#54266)
Currently we set the defaults for ccsMinimizeRoundtrips, preFilterShardSize and
requestCache on the HLRC SubmitAsyncSearchRequest in the constructor. This is no
longer needed since we now only send the parameters along with the rest request
that are supported (omitting e.g. ccsMinimizeRoundtrips) and the correct
defaults are set on the client side. This change removes setting and sending
these defaults where possible, leaving only the overwrite of batchedReduceSize
with a default value of 5, since the default used in the vanilla SearchRequest
is 512. However, we don't need to send this value along as a request parameter
if its the default since the correct one will be set on the receiving end if no
value is specified.
Also adding tests for RestSubmitAsyncSearchAction that check the correct
defaults are set when parameters are missing on the server side.

[7.x][ML] Data frame analytics data counts (#53998) (#54031)
This commit instruments data frame analytics
with stats for the data that are being analyzed.
In particular, we count training docs, test docs,
and skipped docs.

In order to account docs with missing values as skipped
docs for analyses that do not support missing values,
this commit changes the extractor so that it only ignores
docs with missing values when it collects the data summary,

Add heuristics to compute pre_filter_shard_size when unspecified (#53873) (#54007)
This commit changes the pre_filter_shard_size default from 128 to unspecified.
This allows to apply heuristics based on the request and the target indices when deciding
whether the can match phase should run or not. When unspecified, this pr runs the can match phase
automatically if one of these conditions is met:
  * The request targets more than 128 shards.
  * The request contains read-only indices.
  * The primary sort of the query targets an indexed field.
Users can opt-out from this behavior by setting the `pre_filter_shard_size` to a static value.

Backport of async search changes (#53976)
* Get Async Search: omit _clusters section when empty (#53907)

The _clusters section is omitted by the search API whenever no remote clusters are searched. Async search should do the same, but Get Async Search returns a deserialized response, hence a weird `_clusters` section with all values set to `0` gets returned instead. In fact the recreated Clusters object is not the same object as the EMPTY constant, yet it has the same content.

This commit addresses this by changing the comparison in the `toXContent` method to not print out the section if the number of total clusters is `0`.

* Async search: remove version from response (#53960)

The goal of the version field was to quickly show when you can expect to find something new in the search response, compared to when nothing has changed. This can also be done by looking at the `_shards` section and `num_reduce_phases` returned with the search response. In fact when there has been one or more additional reduction of the results, you can expect new results in the search response. Otherwise, the `_shards` section could notify of additional failures of shards that have completed the query, but that is not a guarantee that their results will be exposed (only when the following partial reduction is performed their results will be available).

That said this commit clarifies this in the docs and removes the version field from the async search response

* Async Search: replicas to auto expand from 0 to 1 (#53964)

This way single node clusters that are green don't go yellow once async search is used, while
all the others still have one replica.

* [DOCS] address timing issue in async search docs tests (#53910)

The docs snippets for submit async search have proven difficult to test as it is not possible to guarantee that you get a response that is not final, even when providing `wait_for_completion=0`. In the docs we want to show though a proper long-running query, and its first response should be partial rather than final.

With this commit we adapt the docs snippets to show a partial response, and replace under the hood all that's needed to make the snippets tests succeed when we get a final response. Also, increased the timeout so we always get a final response.

Backport: initial data stream commit (#53959)
This commits adds a data stream feature flag, initial definition of a data stream and
the stubs for the data stream create, delete and get APIs. Also simple serialization
tests are added and a rest test to thest the data stream API stubs.

This is a large amount of code and mainly mechanical, but this commit should be
straightforward to review, because there isn't any real logic.

The data stream transport and rest action are behind the data stream feature flag and
are only intialized if the feature flag is enabled. The feature flag is enabled if
elasticsearch is build as snapshot or a release build and the
'es.datastreams_feature_flag_registered' is enabled.

The integ-test-zip sets the feature flag if building a release build, otherwise
rest tests would fail.

Currently the AbstractBulkByScrollRequest accepts slice values of 0 via its

as invalid by `AbstractBulkByScrollRequest#parseSlices`. Instead of making

requests.

[7.x] Smarter copying of the rest specs and tests (#52114) (#52798)
* Smarter copying of the rest specs and tests (#52114)

This PR addresses the unnecessary copying of the rest specs and allows
for better semantics for which specs and tests are copied. By default
the rest specs will get copied if the project applies
`elasticsearch.standalone-rest-test` or `esplugin` and the project
has rest tests or you configure the custom extension `restResources`.

This PR also removes the need for dozens of places where the x-pack
specs were copied by supporting copying of the x-pack rest specs too.

The plugin/task introduced here can also copy the rest tests to the
local project through a similar configuration.

The new plugin/task allows a user to minimize the surface area of
which rest specs are copied. Per project can be configured to include
only a subset of the specs (or tests). Configuring a project to only
copy the specs when actually needed should help with build cache hit
rates since we can better define what is actually in use.
However, project level optimizations for build cache hit rates are
not included with this PR.

Also, with this PR you can no longer use the includePackaged flag on
integTest task.

The following items are included in this PR:
* new plugin: `elasticsearch.rest-resources`
* new tasks: CopyRestApiTask and CopyRestTestsTask - performs the copy
* new extension 'restResources'
```
restResources {
  restApi {
    includeCore 'foo' , 'bar' //will include the core specs that start with foo and bar
    includeXpack 'baz' //will include x-pack specs that start with baz
  }
  restTests {
    includeCore 'foo', 'bar' //will include the core tests that start with foo and bar

EQL: Add integration tests harness to test EQL feature parity with original implementation (#52248) (#52675)
The tests use the original test queries from

for EQL implementation correctness validation.
The file test_queries_unsupported.toml serves as a "blacklist" for the
queries that we do not support. Currently all of the queries are
blacklisted. Over the time the expectation is to eventually have an
empty "blacklist" when all of the queries are fully supported.

The tests use the original test vector from
https://raw.githubusercontent.com/endgameinc/eql/master/eql/etc/test_data.json.

Only one EQL and the response is stubbed for now to match the expected
output from that query. This part would need some tweaking after EQL is
fully wired.
