Should we change the signature to Optional as well?

Thanks @Bukhtawar for the review. Did you mean updating java doc to mention this method is applicable only for SegRep enabled indices ?

…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 <rishireddy1159@gmail.com> * [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 <handalm@amazon.com> * 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. Signed-off-by: Marc Handalian <handalm@amazon.com> * Wire up Segment Replication under the feature flag. This PR wires up segment replication and adds some initial integration tests. Signed-off-by: Marc Handalian <handalm@amazon.com> * Add test to ensure replicas use primary translog uuid with segrep. Signed-off-by: Marc Handalian <handalm@amazon.com> * Update SegmentReplicationIT to assert previous commit points are valid and SegmentInfos can be built. Fix nitpicks in PR feedback. Signed-off-by: Marc Handalian <handalm@amazon.com> * Fix test with Assert.fail to include a message. Signed-off-by: Marc Handalian <handalm@amazon.com> * 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. Signed-off-by: Marc Handalian <handalm@amazon.com> * Fix isAheadOf logic for ReplicationCheckpoint comparison (#4112) Signed-off-by: Suraj Singh <surajrider@gmail.com> * Fix waitUntil refresh policy for segrep enabled indices.

Move tests to SegmentReplicationIndexShardTests Signed-off-by: Suraj Singh <surajrider@gmail.com> * Add segrep enbaled index settings in TargetServiceTests, SourceHandlerTests Signed-off-by: Suraj Singh <surajrider@gmail.com> * [Segment Replication] Fix OngoingSegmentReplications to key by allocation ID instead of DiscoveryNode. (#4182) * 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. Signed-off-by: Marc Handalian <handalm@amazon.com> * Clean up cancel methods.
