Benjamin Roth commented on CASSANDRA-13226:
-------------------------------------------
Sorry for that many comments, just another thought:
Flushes can be optimized very easily in that way that a flush is only executed
if the memtable contains mutations for the requested range OR if the memtable
exceeds a certain size, so that the check is still cheap. I implemented this
just for fun some months ago but did never create a ticket for it.
