---------------------------------
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.
