[jira] [Created] (HBASE-14352) Replication is terribly slow with
WAL compression
Abhishek Singh Chouhan created HBASE-14352:
----------------------------------------------
Summary: Replication is terribly slow with WAL compression
Key: HBASE-14352
URL: https://issues.apache.org/jira/browse/HBASE-14352
Project: HBase
Issue Type: Bug
Affects Versions: 0.98.13
Reporter: Abhishek Singh Chouhan
For the same load, replication with WAL compression enabled is almost 6x slower than with compression turned off. Age of last shipped operation is also correspondingly much higher when compression is turned on.
By observing Size of log queue we can see that it is taking too much time for the queue to clear up.
Attaching corresponding graphs.
