@iamaleksey I *think* I've resolved all your comments. The last dtest was
all green. I'm not sure about the latest push but I don't forsee any breakages.
Please let me know if there are more changes required.
> Optimize streaming path in Cassandra

> During streaming, Cassandra reifies the sstables into objects. This creates
> unnecessary garbage and slows down the whole streaming process as some
> sstables can be transferred as a whole file rather than individual
> partitions. The objective of the ticket is to detect when a whole sstable can
> be transferred and skip the object reification. We can also use a zero-copy
> path to avoid bringing data into user-space on both sending and receiving
> side.
