Joshua McKenzie commented on CASSANDRA-6993:
--------------------------------------------
Good call on the final.
I also agree on the logic - I simply re-factored the existing logic and took
its correctness at face-value since it was already committed into the code-base.
I'll clean these two things up and post a revised patch - thanks for the
feedback.

> Memory-mapped I/O on Windows causes issues with hard-links; we're unable to
> delete hard-links to open files with memory-mapped segments even using nio.
> We'll need to push for close to performance parity between mmap'ed I/O and
> buffered going forward as the buffered / compressed path offers other
> benefits.
