-----------------------------------
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.
