Andrew Purtell commented on HBASE-14352:
----------------------------------------
When I've tested wal compression I've found the hit to write performance
(increased latency leading to a lower aggregate write ceiling cluster-wide) to
outweigh space savings and any gains from that. Is this the general experience?
Maybe the answer is to deprecate 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
> Attachments: age_of_last_shipped.png, size_of_log_queue.png
>
>
> 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.
