> Use AsyncConnection in ReplicationSink
> --------------------------------------
>
> Key: HBASE-26950
> URL: https://issues.apache.org/jira/browse/HBASE-26950
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 2.4.11
> Reporter: Bryan Beaudreault
> Assignee: chenglei
> Priority: Major
> Labels: branch-2, replication
> Fix For: 2.5.0, 2.6.0
>
>
> We don't need to necessarily rewrite ReplicationSink to work fully async. I
> think it would simply benefit from ConnectionFactory.createAsyncConnection
> instead of ConnectionFactory.createConnection.
> The reasons for this are:
> * AsyncConnection is the more modern implementation, the only implementation
> in master, and where most of the efforts will be going forward.
> * ReplicationSink only does batch calls, and batch calls are done with
> AsyncProcess. It's likely that the native AsyncTable is better than
> AsyncProcess for this.
> ** One specific example, AsyncProcess calls findAllLocationsOrFail
> sequentially for all actions in a batch. This can take quite a while with the
> default replication batch size of 5k, if actions are spread across many
> regions. In AsyncTable, these calls are done in parallel
