------------------------------------------

             Summary: Windows: remove mmap'ed I/O for index files and force standard file
access
                 Key: CASSANDRA-6993
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6993
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Joshua McKenzie
            Assignee: Joshua McKenzie
            Priority: Minor
             Fix For: 3.0


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.
