Description

Segment Replication - Remove unnecessary call to markAllocationIdAsInSync.

This PR Removes an unnecessary call to markAllocationIdAsInSync on the primary shard when replication events complete.
Recovery will manage this, segment replication does not need to mark the id in sync. After replication events we update replicas with segments, advancing its processed checkpoint. Persisted checkpoints, which drive the local checkpoint calculation on each shard, will be unchanged during these events. Only xlog syncs advance the local checkpoint.

…aining segment replication changes (#4243)

* [Segment Replication] Checkpoint Replay on Replica Shard (#3658)

* Adding Latest Recevied checkpoint, replay checkpoint logic along with tests

Signed-off-by: Rishikesh1159 <[email protected]>

* [Segment Replication] Wire up segment replication with peer recovery and add ITs. (#3743)

* Add null check when computing max segment version.

With segment replication enabled it is possible Lucene does not set the SegmentInfos
min segment version, leaving the default value as null.

Signed-off-by: Marc Handalian <[email protected]>

* Update peer recovery to set the translogUUID of replicas to the UUID generated on the primary.

This change updates the UUID when the translog is created to the value stored in the passed segment userdata.
This is to ensure during failover scenarios that the replica can be promoted and not have a uuid mismatch with the value stored in user data.

* Disable shard idle with segment replication. (#4118)

This change disables shard idle when segment replication is enabled.
Primary shards will only push out new segments on refresh, we do not want to block this based on search behavior.
Replicas will only refresh on an externally provided SegmentInfos, so we do not want search requests to hang waiting for a refresh.

* Fix OngoingSegmentReplications to key by allocation ID instead of DiscoveryNode.

This change fixes segrep to work with multiple shards per node by keying ongoing replications on
allocation ID.  This also updates cancel methods to ensure state is properly cleared on shard cancel.
