> Async WAL replication for region replicas
> -----------------------------------------
>
> Key: HBASE-11568
> URL: https://issues.apache.org/jira/browse/HBASE-11568
> Project: HBase
> Issue Type: Sub-task
> Reporter: Enis Soztutar
> Assignee: Enis Soztutar
> Fix For: 2.0.0
>
> Attachments: hbase-11568_v2.patch
>
>
> As mentioned in parent issue, and design docs for phase-1 (HBASE-10070) and
> Phase-2 (HBASE-11183), implement asynchronous WAL replication from the WAL
> files of the primary region to the secondary region replicas.
> The WAL replication will build upon the pluggable replication framework
> introduced in HBASE-11367, and the distributed WAL replay.
> Upon having some experience with the patch, we changed the design so that
> there is only one replication queue for doing the async wal replication to
> secondary replicas rather than having a queue per region replica. This is due
> to the fact that, we do not want to tail the logs of every region server for
> a single region replica.
> Handling of flushes/compactions and memstore accounting will be handled in
> other subtasks.
