-------------------------------------------
Summary: Add flag to avoid invalidating key cache on file deletion
Key: CASSANDRA-20068
URL: https://issues.apache.org/jira/browse/CASSANDRA-20068
Project: Cassandra
Issue Type: Improvement
Reporter: Marcus Eriksson
Assignee: Marcus Eriksson
CASSANDRA-17056 changed the way we invalidate key cache when deleting sstables
after compaction. It now iterates over all the keys in the keycache and deletes
the key if it is for the current sstable.
It can potentially take several seconds per deleted sstable to do this.
Patch attached which disables this by default, but can be turned on if anyone
relies on this.
