[jira] [Reopened] (CASSANDRA-3497) BloomFilter FP ratio should be configurable or size-restricted some other way
[ https://issues.apache.org/jira/browse/CASSANDRA-3497?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Jonathan Ellis reopened CASSANDRA-3497: --- BloomFilter FP ratio should be configurable or size-restricted some other way - Key: CASSANDRA-3497 URL: https://issues.apache.org/jira/browse/CASSANDRA-3497 Project: Cassandra Issue Type: New Feature Components: Core Reporter: Brandon Williams Assignee: Yuki Morishita Priority: Minor Fix For: 1.0.7 Attachments: 0001-give-default-val-to-fp_chance.patch, 3497-v3.txt, 3497-v4.txt, CASSANDRA-1.0-3497.txt When you have a live dc and purely analytical dc, in many situations you can have less nodes on the analytical side, but end up getting restricted by having the BloomFilters in-memory, even though you have absolutely no use for them. It would be nice if you could reduce this memory requirement by tuning the desired FP ratio, or even just disabling them altogether. -- This message is automatically generated by JIRA.
