This commit speeds up GeoShapeQueryTests by reducing the size of the random generated shapes and defaulting geo_shape indexes to use quadtree (more efficient for shapes) over geohash.
test failed, because now the percolator returns upto 10 matches whereas before this was unbounded. The test has been updated to take this in account by checking the total count instead of the number of matches
This commit cleans up some of the assertions in
TransportReplicationActionTests#runReplicateTest:
- use a Map to track actual vs. expected requests
- assert that no request was sent to the local node
- use RoutingTable#shardRoutingTable convenience method
- explicitly use false in boolean conditions
- clarify requests are expected on replica shards when assigned and
execution on replicas is true
- test ShardRouting equality when checking the failed shard request
This commit adds tighter assertions in
TransportReplicationActionTests#runReplicateTest that replication
requests are sent to the correct shard copies.
This commit addresses an issue when handling a failed replication
request against a relocating target shard. Namely, if a replication
request fails against the target of a relocation we currently fail both
the source and the target. This leads to an unnecessary
recovery. Instead, only the target of the relocation should be failed.
* Added percolator field mapper that extracts the query terms and indexes these terms with the percolator query.
* At percolate time these extracted terms are used to query percolator queries that are like to be evaluated. This can significantly cut down the time it takes to percolate. Whereas before all percolator queries were evaluated if they matches with the document being percolated.
* Changes made to percolator queries are no longer immediately visible, a refresh needs to happen before the changes are visible.
* By default the percolate api only returns upto 10 matches instead of returning all matching percolator queries.
* Made percolate more modular, so that it is easier to add unit tests.
* Added unit tests for the percolator.

We today delete the translog-N.tlog file if any subsequent operation fails
but we might actually be in a good state if for instance the creation of the writer
failes after we sucessfully baked the new translog generation into the checkpoint. In this situation
we used to delete the translog-N.tlog file and failed on the next recovery of the translog with a
NoSuchFileException | FileNotFoundException just like in https://discuss.elastic.co/t/cannot-recover-index-because-of-missing-tanslog-files/38336
This commit changes the behavior and cleans up that limbo state on recovery if we already have a generation+1 file written but not baked into
the checkpoint we remove that file but only if the previous ckp file has already been renamed otherwise we know we can't be in this state.
We has a postIndex|DeleteUnderLock listener callback to load percolator
queries which is entirely private to the index shard in the meanwhile. Yet,
it still calls an external callback while holding an indexing lock which is scary
since we have no control over how long the operation could possibly take.
This commit decouples the percolator registry entirely from the ShardIndexingService
by pessimistically fetching percolator documents from the the engine using realtime get.
Even in situations where the same document is changed concurrently we will eventually end up
in the correct state without loosing an update. This also moves the index throtteling stats directly into
the engine to entirely remove the need for the dependency between InternalEngine and ShardIndexingService.
Relocating a non-primary shard from one node to another is actually done by recovering from the active
primary shard in the cluster, and not the node that we are logically relocating from.
Closes#15775
This commit addresses an issue where a cluster state task listener
throwing an exception could prevent other listeners from being notified,
and could prevent the executor from receiving notifications that a new
cluster state was published. Additionally, this commit also addresses a
similar issue for executors handling cluster state publication
notifications.
Adds task manager class and enables all activities to register with the task manager. Currently, the immutable Transport*Activity class represents activity itself shared across all requests. This PR adds and an additional structure Task that keeps track of currently running requests and can be used to communicate with these requests using TransportTaskAction.

We used to write into an in-memory buffer and if necessary also allow reading
from the memory buffer if the some translog locations that are not flushed to
the channel need to be read. This commit hides all writing behind a buffered output
stream and if ncecessary flushes all buffered data to the channel for reading. This allows
for several simplifcations like reusing javas build in BufferedOutputStream and removes the
need for read write locks on the translog writer. All thread safety is now achived using
the synchronized primitive.
Several IOExceptions are always wrapped in an NotSerializableWrapper which is
annoying to read. These exceptions are important to get right across the network
and we should support the important ones that indicate problems on the Filesystem.
This commit also adds general support for IOException to preserve the parent type
across the network if no specific type is serializable.
As a default in V2, the GeoPointField.stored option was set to true. Since this consumes disk space with no positive benefit the default stored option is being reverted back to false.
This commit restores logging the ShardRouting#shardId at the front of
the log messages in ShardStateAction. The reason for this is so that
shard-level log messages have the format "[component][node][shard]
message".
There are two bugs:
- the 'global_ordinals_low_cardinality' mode requires a fielddata-based impl so
that it can extract the segment to global ordinal mapping
- the 'global_ordinals_hash' mode abusively casts to the values source to a
fielddata-based impl while it is not needed
Closes#14882
This commit modifies the handling of cluster states in
o.e.c.a.s.ShardStateAction so that all necessary state is obtained
externally to the ShardStateAction#shardFailed and
ShardStateAction#shardStarted methods. This refactoring permits the
removal of the ClusterService field from ShardStateAction.
This commit applies a minor code cleanup to
o/e/c/ClusterStateObserver.java. In particular
- employ the diamond operator instead of explicitly specifying a
generic type parameter
- use 'L' instead of 'l' for specifying a long literal
- remove redundant static modifier on a nested interface
- remove redundant public access modifiers on interface methods
- reformat the declaration of the four-argument ChangePredicate#apply
- simplify the bodies of ValidationPredicate#apply
