Enis Soztutar commented on HBASE-10201:
---------------------------------------

I don't think we should have this in 1.0.0. I am planning on cutting the RC 
tomorrow, and this seems to be a huge change for the last minute. Can we target 
1.1 instead?

> Currently the flush decision is made using the aggregate size of all column 
> families. When large and small column families co-exist, this causes many 
> small flushes of the smaller CF. We need to make per-CF flush decisions.
