Description

This would enable routing different partitions to different disks based on some user defined parameters.

My initial take on how to do this would be to make an interface from SSTableWriter, and have a table's compaction strategy do all SSTableWriter instantiation. Compaction strategies could then implement their own SSTableWriter implementations (which basically wrap one or more normal sstablewriters) for compaction, flushing, and streaming.
