Jonathan Ellis commented on CASSANDRA-3741:
-------------------------------------------

No, this is a sensitive area of the code and we don't want to risk destabilizing it.

>    Affects Versions: 1.0.0
>         Environment: FreeBSD

> Currently we are moving to new data format where new format is written into new CFs and old one is deleted key-by-key. 
> I have started getting OOMs and found out that delete operations are not accounted and so, column families are not flushed (changed == 0 with delete only operations) by storage manager.
> This is pull request that fixed this problem for me: https://github.com/apache/cassandra/pull/5
