* Change fastForwardProcessedSeqNo method in LocalCheckpointTracker to persisted checkpoint. This change inverts fastForwardProcessedSeqNo to fastForwardPersistedSeqNo for use in Segment Replication. This is so that a Segrep Engine can match the logic of InternalEngine where the seqNo is incremented with each operation, but only persisted in the tracker on a flush. With Segment Replication we bump the processed number with each operation received index/delete/noOp, and invoke this method when we receive a new set of segments to bump the persisted seqNo. Signed-off-by: Marc Handalian <handalm@amazon.com> * Extract Translog specific engine methods into an abstract class. This change extracts translog specific methods to an abstract engine class so that other engine implementations can reuse translog logic. Signed-off-by: Marc Handalian <handalm@amazon.com> * Add a separate Engine implementation for replicas with segment replication enabled. This change adds a new engine intended to be used on replicas with segment replication enabled. This engine does not wire up an IndexWriter, but still writes all operations to a translog. The engine uses a new ReaderManager that refreshes from an externally provided SegmentInfos. Signed-off-by: Marc Handalian <handalm@amazon.com> * Fix spotless checks. Signed-off-by: Marc Handalian <handalm@amazon.com> * Fix :server:compileInternalClusterTestJava compilation. Signed-off-by: Marc Handalian <handalm@amazon.com> * Fix failing test naming convention check. Signed-off-by: Marc Handalian <handalm@amazon.com> * PR feedback. - Removed isReadOnlyReplica from overloaded constructor and added feature flag checks. - Updated log msg in NRTReplicationReaderManager - cleaned up store ref counting in NRTReplicationEngine. Signed-off-by: Marc Handalian <handalm@amazon.com> * Fix spotless check. Signed-off-by: Marc Handalian <handalm@amazon.com> * Remove TranslogAwareEngine and build translog in NRTReplicationEngine. Signed-off-by: Marc Handalian <handalm@amazon.com> * Fix formatting Signed-off-by: Marc Handalian <handalm@amazon.com> * Add missing translog methods to NRTEngine. Signed-off-by: Marc Handalian <handalm@amazon.com> * Remove persistent seqNo check from fastForwardProcessedSeqNo. Signed-off-by: Marc Handalian <handalm@amazon.com> * PR feedback. Signed-off-by: Marc Handalian <handalm@amazon.com> * Add test specific to translog trimming. Signed-off-by: Marc Handalian <handalm@amazon.com> * Javadoc check. Signed-off-by: Marc Handalian <handalm@amazon.com> * Add failEngine calls to translog methods in NRTReplicationEngine. Roll xlog generation on replica when a new commit point is received.

Welcome!
OpenSearch is a community-driven, open source fork of Elasticsearch and Kibana following the licence change in early 2021. We're looking to sustain (and evolve!) a search and analytics suite for the multitude of businesses who are dependent on the rights granted by the original, Apache v2.0 License.
