Brandon Williams reassigned CASSANDRA-1099: ------------------------------------------- Assignee: Brandon Williams > make CFS.flushWriter_ size configurable > --------------------------------------- > > Key: CASSANDRA-1099 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1099 > Project: Cassandra > Issue Type: New Feature > Components: Core > Reporter: Jonathan Ellis > Assignee: Brandon Williams > Priority: Minor > Fix For: 0.7 > > Attachments: 1099.txt > > > For small heaps (including our out-of-the-box 1G) we want to allow reducing > this from the automatic (1 + 2 * > DatabaseDescriptor.getAllDataFileLocations().length); having 3 memtables in > the queue, plus another being written, is over 200MB which is a significant > amount of data for the GC to chew through (see CASSANDRA-1014). > For large heaps, we might also want to allow *increasing* this value, to > accommodate load spikes better. > Unfortunately making this configurable at runtime does not appear to be an > option due to the lack of a setCapacity method on any of the BlockingQueue > classes. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
