--------------------------------------

@Nicolas,
Is there any update on this issue? We have a production use-case wherein 80% of data goes to one CF and remaining 20% goes to two other CFs. I can collaborate with you if you are interested to pursue with patch. Thanks.

> Today, 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.
