Benedict created CASSANDRA-8434: ----------------------------------- Summary: L0 should have a separate configurable bloom filter false positive ratio Key: CASSANDRA-8434 URL: https://issues.apache.org/jira/browse/CASSANDRA-8434 Project: Cassandra Issue Type: Improvement Components: Core Reporter: Benedict Fix For: 2.0.12, 2.1.3
In follow up to CASSANDRA-5371. We now perform size-tiered file selection for compaction if L0 gets too far behind, however as far as I can tell we stick with the CF configured false positive ratio, likely inflating substantially the number of files we visit on average until L0 is cleaned up. Having a a different bf fp for L0 would solve this problem without introducing any significant burden when L0 is not overloaded. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
