 URL: https://issues.apache.org/jira/browse/HBASE-5716
 Project: HBase
  Issue Type: Improvement
Reporter: Jean-Daniel Cryans
Assignee: Li Pi

 HBASE-4608 is a nice feature but after playing with it for a while I think 
 the following should be fixed to make it easier to use by someone who's not a 
 dev:
  - Add some signal that says that the feature is turned on. Right now you can 
 {{jstack | grep KeyValueCompression}} a couple of times and if you get a hit 
 you definitely know it's on, but otherwise the random user wouldn't know 
 without going through the jira.
  - Add documentation in the reference guide. At the minimum add 
 {{hbase.regionserver.wal.enablecompression}} in there with a small 
 description. Better would be to add a section in {{Appendix B}} or something 
 like that and describe the functionality a bit and who it's useful for. For 
 example, flush from your brain the knowledge of the patch and read the name 
 of the configuration... now let's say you have a use case that involves 
 writing easily compressible values. Any normal user would believe that this 
 is a good tuning parameter for them, but it's just going to waste CPU cycles.
  - Add some metrics like we have for HFiles where you get a clue about the 
 compression ratio.
