Eshcar Hillel commented on HBASE-16417:
---------------------------------------

bq. Ya that is the default right? It should be enabled using a config for 
specific kind of workload.

Indeed, currently the default is no compaction (default memstore) and when 
setting in memory compaction to true the default is index compaction (not data 
compaction).
In this Jira we plan to explore different policies and evaluate their pros and 
cons.
In my comment I was referring to a plausible policy (not implemented yet) that 
would allow for data compaction however would avoid it when it is not likely to 
incur any benefit.
