* Introduce Spatial Plugin (#44389)
Introduce a skeleton Spatial plugin that holds new licensed features coming to
Geo/Spatial land!
* [GEO] Refactor DeprecatedParameters in AbstractGeometryFieldMapper (#44923)
Refactor DeprecatedParameters specific to legacy geo_shape out of
AbstractGeometryFieldMapper.TypeParser#parse.
* [SPATIAL] New ShapeFieldMapper for indexing cartesian geometries (#44980)
Add a new ShapeFieldMapper to the xpack spatial module for
indexing arbitrary cartesian geometries using a new field type called shape.
The indexing approach leverages lucene's new XYShape field type which is
backed by BKD in the same manner as LatLonShape but without the WGS84
latitude longitude restrictions. The new field mapper builds on and
extends the refactoring effort in AbstractGeometryFieldMapper and accepts
shapes in either GeoJSON or WKT format (both of which support non geospatial
geometries).
Tests are provided in the ShapeFieldMapperTest class in the same manner
as GeoShapeFieldMapperTests and LegacyGeoShapeFieldMapperTests.
Documentation for how to use the new field type and what parameters are
accepted is included. The QueryBuilder for searching indexed shapes is
provided in a separate commit.
* [SPATIAL] New ShapeQueryBuilder for querying indexed cartesian geometry (#45108)
Add a new ShapeQueryBuilder to the xpack spatial module for
querying arbitrary Cartesian geometries indexed using the new shape field
type.
The query builder extends AbstractGeometryQueryBuilder and leverages the
ShapeQueryProcessor added in the previous field mapper commit.
Tests are provided in ShapeQueryTests in the same manner as
GeoShapeQueryTests and docs are updated to explain how the query works.
* It's in the title, follow up to #45233
* Flatten more listeners into `StepListener`
* Remove duplication from repo and index bootstrap and asserting that the steps execute successfully
* If `counter.onResult` throws an exception we might leak a transport task because the failure is not handled as a phase failure (instead it bubbles up in the transport service eventually hitting the `onFailure` callback again and couting down the `counter` twice).

Currently, when adding a new mapping, we attempt to parse + merge it before
checking whether its top-level document type matches the existing type. So when
a user attempts to introduce a new mapping type, we may give a confusing error
message around merging instead of complaining that it's not possible to add
more than one type ("Rejecting mapping update to [my-index] as the final
mapping would have more than 1 type...").
This PR moves the type validation to the start of
`MetaDataMappingService#applyRequest` so that we make sure the type matches
before performing any mapper merging.
We already partially addressed this issue in #29316, but the tests there
focused on `MapperService` and did not catch this problem with end-to-end
mapping updates.
Addresses #43012.
We accidentally introduced this bug when adding a typeless version of the
rollover request. The bug is not present if include_type_name is set to true.
The previous hasProcessors method would validate if a processor was
present within a pipeline, but would not return the contents of the
processors. This does not allow a consumer to inspect the processor for
specific metadata. The method now returns the list of processors based
on the class of the processor passed in.
Because auto-date-histo can perform multiple reductions while
merging buckets, we need to ensure that the intermediate reductions
are done with a `finalReduce` set to false to prevent Pipeline aggs
from generating their output.
Once all the buckets have been merged and the output is stable,
a mostly-noop reduction can be performed which will allow pipelines
to generate their output.
This commit makes sure that mapping parameters to `CreateIndex` and
`PutIndexTemplate` are keyed by the type name.
`IndexCreationTask` expects mappings to be keyed by the type name.
It asserts this for template mappings but not for the mappings in the request.
The `CreateIndexRequest` and `RestCreateIndexAction` mostly make it sure
that the mapping is keyed by a type name, but not always.
When building the create-index request outside of the REST handler, there are
a few methods to set the mapping for the request. Some of them add the type
name some of them do not.
For example, `CreateIndexRequest#mapping(String type, Map<String, ?> source)`
adds the type name, but
`CreateIndexRequest#mapping(String type, XContentBuilder source)` does not.
This PR asserts the type name in the request mapping inside `IndexCreationTask`
and makes all `CreateIndexRequest#mapping` methods add the type name.
testShouldFlushAfterPeerRecovery was added #28350 to make sure the
flushing loop triggered by afterWriteOperation eventually terminates.
This test relies on the fact that we call afterWriteOperation after
making changes in translog. In #44756, we roll a new generation in
RecoveryTarget#finalizeRecovery but do not call afterWriteOperation.

Today, if an operation-based peer recovery occurs, we won't trim
translog but leave it as is. Some unacknowledged operations existing in
translog of that replica might suddenly reappear when it gets promoted.
With this change, we ensure trimming translog above the starting
sequence number of phase 2. This change can allow us to read translog
forward.
* Follow up to #44949
* Stop using a special code path for multi-line JSON and instead handle its detection like that of other XContent types when creating the request
* Only leave a single path that holds a reference to the full REST request
* In the next step we can move the copying of request content to happen before the actual request handling and make it conditional on the handler in question to stop copying bulk requests as suggested in #44564
* Reduces complicated callback relations in `testSuccessfulSnapshotAndRestore` to flat steps of sequential actions
* Will refactor the other tests in this suit as a follow up
* This format certainly makes it easier to create more complicated tests that involve multiple subsequent snapshots as it would allow adding loops
When having a cluster state from 6.x, display the metadata version as the cluster state version.
Avoids confusion where a cluster state from 6.x is displayed as version 0 even if has some actual
content.
Today if a shard is not fully allocated we maintain a retention lease for a
lost peer for up to 12 hours, retaining all operations that occur in that time
period so that we can recover this replica using an operations-based recovery
if it returns. However it is not always reasonable to perform an
operations-based recovery on such a replica: if the replica is a very long way
behind the rest of the replication group then it can be much quicker to perform
a file-based recovery instead.
This commit introduces a notion of "reasonable" recoveries. If an
operations-based recovery would involve copying only a small number of
operations, but the index is large, then an operations-based recovery is
reasonable; on the other hand if there are many operations to copy across and
the index itself is relatively small then it makes more sense to perform a
file-based recovery. We measure the size of the index by computing its number
of documents (including deleted documents) in all segments belonging to the
current safe commit, and compare this to the number of operations a lease is
retaining below the local checkpoint of the safe commit. We consider an
operations-based recovery to be reasonable iff it would involve replaying at
most 10% of the documents in the index.
The mechanism for this feature is to expire peer-recovery retention leases
early if they are retaining so much history that an operations-based recovery
using that lease would be unreasonable.

CellIdSource is a helper ValuesSource that encodes GeoPoint
into a long-encoded representation of the grid bucket the point
is associated with. This complicates thing as usage evolves to
support shapes that are associated with more than one bucket ordinal.
Today the test waits for one of the shards to be blocked, but this does not
mean that the block has been applied on all nodes, so a subsequent indexing
operation may still go through.
Fixes#45338
The client and remote hit sources had each their own retry mechanism,
which would do the same. Supporting resiliency we would have to expand
on the retry mechanisms and as a preparation for that, the retry
mechanism is now shared such that each sub class is only responsible for
sending requests and converting responses/failures to common format.
Part of #42612
Refreshes happening during indexing can result differen segment counts and
slightly skewed term statistics, which in turn has the potential to change
suggestion output slightly. In order to prevent this, disable refresh for the
affected tests.
Closes#43261
`newSearcher()` from lucene can randomly choose index readers which
are not compatible with our tests, like ParallelCompositeReader.
The `newIndexSearcher()` method on AggregatorTestCase is a wrapper
similar to newSearcher but compatible with our tests
This commit adds a helper method to the ingest service allowing it to
inspect a pipeline by id and verify the existence of a processor in the
pipeline. This work exposed a potential bug in that some processors
contain inner processors that are passed in at instantiation. These
processors needed a common way to expose their inner processors, so the
WrappingProcessor was created in order to expose the inner processor.
If a node exceeds the flood-stage disk watermark then we add a block to all of
its indices to prevent further writes as a last-ditch attempt to prevent the
node completely exhausting its disk space. However today this block remains in
place until manually removed, and this block is a source of confusion for users
who current have ample disk space and did not even realise they nearly ran out
at some point in the past.
This commit changes our behaviour to automatically remove this block when a
node drops below the high watermark again. The expectation is that the high
watermark is some distance below the flood-stage watermark and therefore the
disk space problem is truly resolved.
Fixes#39334
The reason field of DefaultShardOperationFailedException is lost during serialization.
This is sad because this field is checked for nullity during xcontent generation and it
means that the cause won't be included in the generated xcontent and won't be
printed in two REST API responses (Close Index API and Indices Shard Stores API).
This commit simply restores the reason from the cause during deserialization.
Adds a tighter threshold for logging a warning about slowness in the
`MasterService` instead of relying on the cluster service's 30-second warning
threshold. This new threshold applies to the computation of the cluster state
update in isolation, so we get a warning if computing a new cluster state
update takes longer than 10 seconds even if it is subsequently applied quickly.
It also applies independently to the length of time it takes to notify the
cluster state tasks on completion of publication, in case any of these
notifications holds up the master thread for too long.

This commit applies a normalization process to environment paths, both
in how they are stored internally, also their settings values. This
normalization is done via two means:
- we make the paths absolute
- we remove redundant name elements from the path (what Java calls
"normalization")
This change ensures that when we compare and refer to these paths within
the system, we are using a common ground. For example, prior to the
change if the data path was relative, we would not compare it correctly
to paths from disk usage. This is because the paths in disk usage were
being made absolute.
Uses JDK 11's per-socket configuration of TCP keepalive (supported on Linux and Mac), see
https://bugs.openjdk.java.net/browse/JDK-8194298, and exposes these as transport settings.
By default, these options are disabled for now (i.e. fall-back to OS behavior), but we would like
to explore whether we can enable them by default, in particular to force keepalive configurations
that are better tuned for running ES.
This adjusts the `buckets_path` parser so that pipeline aggs can
select specific buckets (via their bucket keys) instead of fetching
the entire set of buckets. This is useful for bucket_script in
particular, which might want specific buckets for calculations.
It's possible to workaround this with `filter` aggs, but the workaround
is hacky and probably less performant.
- Adjusts documentation
- Adds a barebones AggregatorTestCase for bucket_script
- Tweaks AggTestCase to use getMockScriptService() for reductions and
pipelines. Previously pipelines could just pass in a script service
for testing, but this didnt work for regular aggs. The new
getMockScriptService() method fixes that issue, but needs to be used
for pipelines too. This had a knock-on effect of touching MovFn,
AvgBucket and ScriptedMetric
Introduce shift field to MovingFunction aggregation.
By default, shift = 0. Behavior, in this case, is the same as before.
Increasing shift by 1 moves starting window position by 1 to the right.
To simply include current bucket to the window, use shift = 1
For center alignment (n/2 values before and after the current bucket), use shift = window / 2
For right alignment (n values after the current bucket), use shift = window.
* Resolve TODO in `readString` by moving to reading chunks of `byte[]` instead of going byte by byte
* Motivated by `readString` showing up as a significant user of CPU time on the IO thread in Rally PMC benchmark
* Benchmarking this:
* Could not reproduce a slowdown in the potential worst case (one or two non-ascii chars) since in this case the cost of creating the string itself exceeds the read times anyway
* Speedup for 50%+ for reading 200 char ascii strings from `ByteBuf` or pages bytes backed streams
* Longer strings obviously get bigger speedups
* More ascii chars -> more speedup
This commit switches to using the full hash to build into the JAR
manifest, which is used in node startup and the REST main action to
display the build hash.
Currently in the transport-nio work we connect and bind channels on the
a thread before the channel is registered with a selector. Additionally,
it is at this point that we set all the socket options. This commit
moves these operations onto the event-loop after the channel has been
registered with a selector. It attempts to set the socket options for a
non-server channel at registration time. If that fails, it will attempt
to set the options after the channel is connected. This should fix
#41071.

Today we recover a replica by copying operations from the primary's translog.
However we also retain some historical operations in the index itself, as long
as soft-deletes are enabled. This commit adjusts peer recovery to use the
operations in the index for recovery rather than those in the translog, and
ensures that the replication group retains enough history for use in peer
recovery by means of retention leases.

* Stop Passing Around REST Request in Multiple Spots
* Motivated by #44564
* We are currently passing the REST request object around to a large number of places. This works fine since we simply copy the full request content before we handle the rest itself which is needlessly hard on GC and heap.
* This PR removes a number of spots where the request is passed around needlessly. There are many more spots to optimize in follow-ups to this, but this one would already enable bypassing the request copying for some error paths in a follow up.
