             Summary: 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
            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.
