Joshua McKenzie commented on CASSANDRA-6993:
--------------------------------------------
ping [~benedict]. Looking for a sanity check that there's no problem disabling
mmap'ed index files on the 2.1 branch on Windows that I'm not thinking of
rather than a code review.
> Windows: remove mmap'ed I/O for index files and force standard file access

> 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.
