Brandon Williams commented on CASSANDRA-4303: --------------------------------------------- It looks like EWAH didn't work out in CASSANDRA-1555, but perhaps it's time to revisit our options. > Compressed bloomfilters > ----------------------- > > Key: CASSANDRA-4303 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4303 > Project: Cassandra > Issue Type: Improvement > Reporter: Brandon Williams > Fix For: 1.2 > > > Very commonly, people encountering an OOM need to increase their bloom filter > false positive ratio to reduce memory pressure, since BFs tend to be the > largest shareholder. It would make sense if we could alleviate the memory > pressure from BFs with compression while maintaining the FP ratio (at the > cost of a bit of cpu) that some users have come to expect.
