ryan rawson commented on HBASE-3149:
------------------------------------

if you are going to generate a sequence id for every CF, then we will
need to create and use a new synthetic ID for atomic views.

> 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.
