Attachment: 0002-an-MBean-attribute-for-displaying-a-flush-counter.patch
This changeset adds a new attribute to the ColumnFamilyStore MBean which
displays the number of times the memtable has been "switched". This attribute
(along with the newly added count and size attributes), should prove useful in
tuning thresholds.
