Johan Oskarsson commented on CASSANDRA-433:
-------------------------------------------

I still see the storage-conf.xml and DatabaseDescriptor entries for the binary memtable that
are removed in Chris' patch in trunk. Is it just waiting to be merged?

> The BinaryMemtable flushes in memory data to disk when the size of the data reaches a
certain limit. There is also a hard coded limit that initiates the flush when more then 50000
items have been inserted. That causes issues if a lot of small items are inserted, we should
remove or make the limit configurable.
