Bartłomiej Romański commented on CASSANDRA-5371: ------------------------------------------------ Ravi, could you confirm that streaming puts all tables in L0? In that case I think we should open a separate issue instead of commenting on a closed one. > Perform size-tiered compactions in L0 ("hybrid compaction") > ----------------------------------------------------------- > > Key: CASSANDRA-5371 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5371 > Project: Cassandra > Issue Type: Bug > Components: Core > Reporter: Jonathan Ellis > Assignee: Jonathan Ellis > Fix For: 2.0 beta 1 > > Attachments: HybridCompactionStrategy.java > > > If LCS gets behind, read performance deteriorates as we have to check bloom > filters on man sstables in L0. For wide rows, this can mean having to seek > for each one since the BF doesn't help us reject much. > Performing size-tiered compaction in L0 will mitigate this until we can catch > up on merging it into higher levels. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
