Jonathan Ellis commented on CASSANDRA-6759: ------------------------------------------- committed > CommitLogSegment should provide madvise DONTNEED hint after syncing a segment > ----------------------------------------------------------------------------- > > Key: CASSANDRA-6759 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6759 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Benedict > Assignee: Benedict > Priority: Minor > Fix For: 2.1 beta2 > > Attachments: 6759.txt > > > This is a really simple change, copying what we do with SequentialWriter, but > here we know for sure we don't intend to re-read the region again in the near > future so it's definitely wasted file buffer space. > I have a patch, but I would like to do some brief performance comparisons > before submitting it, and see if providing DONTNEED at file creation like we > do for SW is sensible. -- This message was sent by Atlassian JIRA (v6.2#6252)
