…project#3658) * Adding Latest Recevied checkpoint, replay checkpoint logic along with tests Signed-off-by: Rishikesh1159 <[email protected]>
…and add ITs. (opensearch-project#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. Signed-off-by: Marc Handalian <[email protected]> * 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 <[email protected]> * Add test to ensure replicas use primary translog uuid with segrep. Signed-off-by: Marc Handalian <[email protected]> * Update SegmentReplicationIT to assert previous commit points are valid and SegmentInfos can be built. Fix nitpicks in PR feedback. Signed-off-by: Marc Handalian <[email protected]> * Fix test with Assert.fail to include a message. Signed-off-by: Marc Handalian <[email protected]>
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 <[email protected]>

…tion ID instead of DiscoveryNode. (opensearch-project#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 <[email protected]> * Clean up cancel methods. Signed-off-by: Marc Handalian <[email protected]> Signed-off-by: Marc Handalian <[email protected]>
