Project: Cassandra
Issue Type: Improvement

With improvements like leveled compaction and CASSANDRA-2503 it's no longer worth throwing quite so much memory at BF to avoid false positives.

[jira] [Updated] (CASSANDRA-4393) Reduce default BF size
Posted by "Jonathan Ellis (JIRA)" <ji...@apache.org>.

Jonathan Ellis updated CASSANDRA-4393:
--------------------------------------
Attachment: 4393.txt
attached.
(to avoid messing with pre-upgrade CF definitions, I've moved the default code out of CFM.init. CreateColumnFamilyStatement already checks the default, so that just left CassandraServer to update.)
