* [Transform] add support for terms agg in transforms (#56696)
This adds support for `terms` and `rare_terms` aggs in transforms.
The default behavior is that the results are collapsed in the following manner:
`<AGG_NAME>.<BUCKET_NAME>.<SUBAGGS...>...`
Or if no sub aggs exist
`<AGG_NAME>.<BUCKET_NAME>.<_doc_count>`
The mapping is also defined as `flattened` by default. This is to avoid field explosion while still providing (limited) search and aggregation capabilities.
This is a followup to #56632. Tests that had to be changed
to mock the C++ log handler more accurately need to be more
careful about when that stream ends, as ending of that
stream is used to detect crashes in the production system.
Fixes#56796
Mapper.Builder currently has some complex generics on it to allow fluent builder
construction. However, the second parameter, a return type from the build() method,
is unnecessary, as we can use covariant return types. This commit removes this second
generic parameter.
This is another part of the breakup of the massive BuildPlugin. This PR
moves the code for configuring publications to a separate plugin. Most
of the time these publications are jar files, but this also supports the
zip publication we have for integ tests.
This aggregation will perform normalizations of metrics
for a given series of data in the form of bucket values.
The aggregations supports the following normalizations
- rescale 0-1
- rescale 0-100
- percentage of sum
- mean normalization
- z-score normalization
- softmax normalization
To specify which normalization is to be used, it can be specified
in the normalize agg's `normalizer` field.
For example:
```
{
"normalize": {
"buckets_path": <>,
"normalizer": "percent"
}
}
```
Optimize away events queries and joins/sequence that cannot match any
results without having to query the backend.

This change ensures that the maintenance service that is responsible for deleting the expired response is stopped between each test. This is needed since we check that no search context are in-flight after each test method.

If an email action is used in a foreach loop, message ids could have
been duplicated, which then get rejected by the mail server.
This commit introduces an additional static counter in the email action
in order to ensure that every message id is unique.
Prior to this change the named pipes that connect the ML C++
processes to the Elasticsearch JVM were all opened before any
of them were read from or written to.
This created a problem, where if the C++ process logged more
messages between opening the log pipe and opening the last
pipe to be connected than there was space for in the named
pipe's buffer then the C++ process would block. This would
mean it never got as far as opening the last named pipe, so
the JVM would never get as far as reading from the log pipe,
hence a deadlock.
This change alters the connection order so that the JVM
starts reading from the logging pipe immediately after opening
it so that if the C++ process logs messages while opening the
other named pipes they are captured in a timely manner and
there is no danger of a deadlock.

This merges the code for the `significant_terms` agg into the package
for the code for the `terms` agg. They are *super* entangled already,
this mostly just admits that to ourselves.

Initial support for EQL sequences
The current algorithm is focused on correctness and does not contain
any optimization which is left for the future.
The current implementation uses a state machine approach which moves
ascending and runs each query one after the other working on computing
sequences as the data comes in.
For each result, the key and its timestamp are being extracted which are
then used for matching/building a sequence.

When decoding async execution ids, exceptions thrown from the decode method itself were not caught, leading to cryptic errors like "Input byte array has incorrect ending byte at 68" being returned. With this commit we return "invalid id: [abcdef]".
Added tests coverage for a couple of these scenarios and also added tests for equals/hashcode methods.
The docs pattern url was using `*` which means zero or many instead
of `?` which means zero or one. The pattern url returned in error
messages was not in sync with the one in the docs.

Today you can convert a searchable snapshot index back into a regular index by
restoring the underlying snapshot, but this is somewhat wasteful if the shards
are already in cache since it copies the whole index from the repository again.
Instead, we can make use of the locally-cached data by using the clone API to
copy the contents of the cache into the layout expected by a regular shard.
This commit marks the searchable snapshot's private index settings as
`NotCopyableOnResize` so that they are removed by resize operations such as
cloning.
Cloning a regular index typically hard-links the underlying files rather than
copying them, but this is tricky to support in the case of a searchable
snapshot so this commit takes the simpler approach of always copying the
underlying files.
This setting was not returned in the SamlRealmSettings#getSettings
so it was not possible for users to set this in the realm config
in our configuration.
Watcher adds watches to the trigger service on the postIndex action
for the .watches index. This has the (intentional) side effect of also
adding the watches to the stats. The tests rely on these stats for their
assertions. The tests also start and stop Watcher between each test for
a clean slate.
When Watcher executes it updates the .watches index and upon this update
it will go through the postIndex method and end up added that watch to the
trigger service (and stats). Functionally this is not a problem, if Watcher
is stopping or stopped since Watcher is also paused and will not execute
the watch. However, with specific timing and expectations of a clean slate
can cause issues the test assertions against the stats.
This commit ensures that the postIndex action only adds to the trigger service
if the Watcher state is not stopping or stopped. When started back up it will
re-read index .watches.
This commit also un-mutes the tests related to #53177 and #56534
This commit allows the JSON schema's documentation.url property to have a null value.
This can useful for cases where a feature is under development, and does not have
documentation published yet.
This commit also adds a documentation.url for two ml resources.
Two spots that allow for some optimization:
* We are often creating a composite reference of just a single item in
the transport layer => special cased via static constructor to make sure we never do that
* Also removed the pointless case of an empty composite bytes ref
* `ByteBufferReference` is practically always created from a heap buffer these days so there
is no point of dealing with all the bounds checks and extra references to sliced buffers from that
and we can just use the underlying array directly
Without the flag we run into the situation where a broken repository (broken by some old 6.x
version of ES that is missing some snap-${uuid}.dat blobs fails to run the SLM retention task
since it always errors out).
Use `ORDER BY` to ensure order of the rows since more
than are returned in the testDate().

This commit adds the ability to auto create data streams using index templates v2.
Index templates (v2) now have a data_steam field that includes a timestamp field,
if provided and index name matches with that template then a data stream
(plus first backing index) is auto created.

* QL: case sensitive support in EQL (#56404)
* adds a generic startsWith function to QL
* modifies the existent EQL startsWith function to be case sensitive
aware
* improves the existent EQL startsWith function to use a prefix query
when the function is used in a case sensitive context. Same improvement
is used in SQL's newly added STARTS_WITH function.
* adds case sensitivity to EQL configuration through a case_sensitive
parameter in the eql request, as established in #54411.
The case_sensitive parameter can be specified when running queries
(default is case insensitive)

The Date/Time related query params of a JDBC prepared statement
serialized using java.util.Date. The rules for serializing
`java.util.Date` objects though reside in
`XContentElasticsearchExtension` which is not available in the
jdbc jar as this class is in `server` module. Therefore, a
custom extension of the `XContentBuilderExtension` iface has been
added to the jdbc module/jar.
Moreover the sql's `qa` project had as dependency the `sql-action`
module which depends on `server` so the `XContentBuilderExtension`
was available for the integ tests hiding the real problem.
Previously, when a user was setting a `java.sql.Time` to the prepStmt,
the DataType used was `DATETIME` instead of `TIME` and therefore
prevented from filtering with a `TIME` casted field:
```
SELECT * FROM test WHERE date::TIME = ?
```

This commit refactors the following:
* GeoPointFieldMapper and PointFieldMapper to
AbstractPointGeometryFieldMapper derived from AbstractGeometryFieldMapper.
* .setupFieldType moved up to AbstractGeometryFieldMapper
* lucene indexing moved up to AbstractGeometryFieldMapper.parse
* new addStoredFields, addDocValuesFields abstract methods for implementing
stored field and doc values field indexing in the concrete field mappers
This refactor is the next phase for setting up a framework for extending
spatial field mapper functionality in x-pack.
Currently Elasticsearch creates independent event loop groups for each
transport (http and internal) transport type. This is unnecessary and
can lead to contention when different threads access shared resources
(ex: allocators). This commit moves to a model where, by default, the
event loops are shared between the transports. The previous behavior can
be attained by specifically setting the http worker count.
This commit removes the `prefer_v2_templates` flag and setting. This was a brief setting that
allowed specifying whether V1 or V2 template should be used when an index is created. It has been
removed in favor of V2 templates always having priority.

This is not a breaking change because this flag was never in a released version.
We are ensuring order in the two tests changed by waiting on latches.
The problem is, that 3s is a pretty short wait and on CI can randomly be exceeded
by pure chance. If that happened we wouldn't have visibility on it since we didn't
assert that the waits actually worked.
=> Fixed by asserting that the waits work and upping the timeout to our standard 10s
Also, moved to a per-test threadpool to make it simpler to identify which test failed,
should an unexpected task run on a closed client's pool afterall.
Async search integration tests are subject to random failures when:
* The test index has more than one replica.
* The request cache is used.
* Some shards are empty.
* The maintenance service starts a garbage collection when node is closing.
They are also slow because the test index is created/populated on each
test method.
This change refactors these integration tests in order to:
* Create the index once for the entire test suite.
* Fix the usage of the request cache and replicas.
* Ensures that all shards have at least one document.
* Increase the delay of the maintenance service garbage collection.

Change TransportBroadcastByNodeAction and TransportBroadcastReplicationAction
to be able to resolve data streams by default. Implementations can change this ability.
This change allows to following APIs to resolve data streams: flush,
refresh (already supported data streams), force merge, clear indices cache,
indices stats (already supported data streams), segments, upgrade stats,
upgrade, validate query, searchable snapshots stats, clear searchable snapshots cache and
reload analyzers APIs.

Right now all implementations of the `terms` agg allocate a new
`Aggregator` per bucket. This uses a bunch of memory. Exactly how much
isn't clear but each `Aggregator` ends up making its own objects to read
doc values which have non-trivial buffers. And it forces all of it
sub-aggregations to do the same. We allocate a new `Aggregator` per
bucket for two reasons:
1. We didn't have an appropriate data structure to track the
sub-ordinals of each parent bucket.
2. You can only make a single call to `runDeferredCollections(long...)`
per `Aggregator` which was the only way to delay collection of
sub-aggregations.
This change switches the method that builds aggregation results from
building them one at a time to building all of the results for the
entire aggregator at the same time.
It also adds a fairly simplistic data structure to track the sub-ordinals
for `long`-keyed buckets.
It uses both of those to power numeric `terms` aggregations and removes
the per-bucket allocation of their `Aggregator`. This fairly
substantially reduces memory consumption of numeric `terms` aggregations
that are not the "top level", especially when those aggregations contain
many sub-aggregations. It also is a pretty big speed up, especially when
the aggregation is under a non-selective aggregation like
the `date_histogram`.
I picked numeric `terms` aggregations because those have the simplest
implementation. At least, I could kind of fit it in my head. And I
haven't fully understood the "bytes"-based terms aggregations, but I
imagine I'll be able to make similar optimizations to them in follow up
changes.
Even with changes from #48854 we're still seeing significant (as in tens and hundreds of MB)
buffer usage for bulk exports in some cases which destabilizes master nodes.
Since we need to know the serialized length of the bulk body we can't do the serialization
in a streaming manner. (also it's not easily doable with the HTTP client API we're using anyway).
=> let's at least serialize on heap in compressed form and decompress as we're streaming to the
HTTP connection. For small requests this adds negligible overhead but for large requests this reduces
the size of the payload field by about an order of magnitude (empirically determined) which is a massive reduction in size when considering O(100MB) bulk requests.
We have been using a zero timeout in the case that DF analytics
is stopped. This may cause a timeout when we cancel, for example,
the reindex task.
This commit fixes this by using the default timeout instead.
