    Description

      HLog based async replication has a challenging to guarantee the in-order delivery when the Region is moving from one HLog stream to another HLog stream.

      One approach is to keep the last_sequence_id in the new HLog stream when opening the Region. So the replication framework is able to catch upto the last_sequence_id from the previous HLog stream, before replicating any new transactions through the new HLog stream.
