Subject [jira] [Created] (CASSANDRA-8271) Remove SSTableDeletingTask
Date Thu, 06 Nov 2014 18:18:33 GMT
Joshua McKenzie created CASSANDRA-8271:
------------------------------------------

             Summary: Remove SSTableDeletingTask
                 Key: CASSANDRA-8271
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8271
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Joshua McKenzie
            Assignee: Joshua McKenzie
            Priority: Minor
             Fix For: 3.0


With CASSANDRA-4050 and CASSANDRA-6993, our out-of-order deletion problems w/regards to Windows
are resolved and the only outstanding reason to have SSTableDeletingTask would be for support
of non-sun VM's w/regards to mmap'ed files.  As this is no longer a big concern in the Cassandra
ecosystem (non-sun VM's), we should remove SSTableDeletingTask.

The one caveat is that if we want to revisit mmap'ed I/O on Windows in the future we may need
to re-use this type of "delayed deletion" approach due to Windows not allowing deletion of
hard linked files w/memory-mapped segments in the original file, but CASSANDRA-5863 would
obviate that concern.
