Phil Yang updated HBASE-17274:
------------------------------
Component/s: Replication
> Add a server level throttler for replication sources
> ----------------------------------------------------
>
> Key: HBASE-17274
> URL: https://issues.apache.org/jira/browse/HBASE-17274
> Project: HBase
> Issue Type: Improvement
> Components: Replication
> Reporter: Phil Yang
> Assignee: Phil Yang
>
> If we have many peers or some servers have many recovered queues, the total
> read size per second from WALs will be very high, which will increase the
> pressure of GC, even maybe OOM because we will read entries for 64MB to
> buffer in default.
> So we should add a server level throttler to limit the speed of reading WALs,
> and limit the total buffered entries for all ReplicationSources.
