Guanghao Zhang commented on HBASE-15995: ---------------------------------------- [~vincentpoon] would you consider putting up a patch also for branch-1? [~tedyu] [~apurtell] This improvement seems not break any compatibility, so this should be merged into branch-1, too? Thanks. > Separate replication WAL reading from shipping > ---------------------------------------------- > > Key: HBASE-15995 > URL: https://issues.apache.org/jira/browse/HBASE-15995 > Project: HBase > Issue Type: Sub-task > Components: Replication > Affects Versions: 2.0.0 > Reporter: Vincent Poon > Assignee: Vincent Poon > Fix For: 2.0.0 > > Attachments: HBASE-15995.master.v1.patch, > HBASE-15995.master.v2.patch, HBASE-15995.master.v3.patch, > HBASE-15995.master.v4.patch, HBASE-15995.master.v6.patch, > HBASE-15995.master.v7.patch, replicationV1_100ms_delay.png, > replicationV2_100ms_delay.png > > > Currently ReplicationSource reads edits from the WAL and ships them in the > same thread. > By breaking out the reading from the shipping, we can introduce greater > parallelism and lay the foundation for further refactoring to a pipelined, > streaming model. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
