-----------------------------------
Summary: Reduce Bloom Filter Garbage Allocation
Key: CASSANDRA-6609
URL: https://issues.apache.org/jira/browse/CASSANDRA-6609
Project: Cassandra
Issue Type: Improvement
Reporter: Benedict
Attachments: tmp.diff
Just spotted that we allocate potentially large amounts of garbage on bloom
filter lookups, since we allocate a new long[] for each hash() and to store the
bucket indexes we visit, in a manner that guarantees they are allocated on
heap. With a lot of sstables and many requests, this could easily be hundreds
of megabytes of young gen churn per second.
