Describe the solution you'd like

  • This assumes index has Segment Replication and Remote Store enabled (remote translog and remote segment store).
  • When fail-over is triggered and the replica to be promoted is lagging, we have two options:
    • Replay operations from remote translog
    • Download segments from remote segment store and replay operations from translog
  • Second option is faster as lesser operations are replayed from translog.
