Stu Hood commented on CASSANDRA-2171:
-------------------------------------
> It's not clear to me what kind of data is useful for CASSANDRA-2156. Why a
> sliding window?
If you flushed x MB in the last 30 minutes, you need to compact at a
proportionate rate. There would also have to be a lower bound to prevent
compaction from stopping completely.
> Record and expose flush rate per CF

> In order to automatically throttle compaction to some multiple of the flush
> rate, we need to record the flush rate across the system. Since this might be
> useful information on a per CF basis, this ticket will deal with recording
> the flush rate in the CFStore object, and exposing it via JMX.
