Joshua McKenzie resolved CASSANDRA-8271.
----------------------------------------
Resolution: Later
Fix Version/s: (was: 3.x)
W/the changes from CASSANDRA-7066, CASSANDRA-9658, and finally CASSANDRA-10222,
removing the various recurring deletion tasks isn't going to be viable until
CASSANDRA-5863 (or some other buffered vs. mmap parity) comes through.
Closing as later pending those efforts.
> 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
>
> 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.
