> URL: https://issues.apache.org/jira/browse/HBASE-10343
> Project: HBase
> Issue Type: Improvement
> Reporter: Liyin Tang
> Priority: Major
>
> 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.
