------------------------------------------
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.
