Gary Dusbabek commented on CASSANDRA-389:
-----------------------------------------

I'm not sure what the historical context of the streaming directory is.  I'll go about looking for a way to remove it today.

> As we continue to make changes to the on-disk format of SSTables, I propose we start versioning. The easiest way without breaking backwards compatibility is to store the version in the filename. This would allow us to figure out the version without looking at the SSTable data. After speaking to Jonathan here is the proposed example:
> <CF>-<ID>-<VERSION>-<DATA|INDEX|FILTER>
