-------------------------------------------
Summary: 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. One possible
implementation is at http://code.google.com/p/javaewah/
