Wei Deng updated CASSANDRA-8434:
--------------------------------
Labels: las (was: )
> 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
> Reporter: Benedict
> Labels: lcs
> Fix For: 2.1.x
>
>
> 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.
