C. Scott Andreas updated CASSANDRA-6633: ---------------------------------------- Component/s: Core > Dynamic Resize of Bloom Filters > ------------------------------- > > Key: CASSANDRA-6633 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6633 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Benedict > Priority: Minor > Labels: performance > Fix For: 4.x > > > Dynamic resizing would be useful. The simplest way to achieve this is to have > separate address spaces for each hash function, so that we may > increase/decrease accuracy by simply loading/unloading another function (we > could even do interesting stuff in future like alternating the functions we > select if we find we're getting more false positives than should be expected); > Faster loading/unloading would help this, and we could achieve this by > mmapping the bloom filter representation on systems that we can mlock. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
