Jonathan Ellis updated CASSANDRA-8329: -------------------------------------- Reviewer: Yuki Morishita > LeveledCompactionStrategy should split large files across data directories > when compacting > ------------------------------------------------------------------------------------------ > > Key: CASSANDRA-8329 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8329 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: J.B. Langston > Assignee: Marcus Eriksson > Fix For: 2.0.12 > > Attachments: > 0001-get-new-sstable-directory-for-every-new-file-during-.patch > > > Because we fall back to STCS for L0 when LCS gets behind, the sstables in L0 > can get quite large during sustained periods of heavy writes. This can > result in large imbalances between data volumes when using JBOD support. > Eventually these large files get broken up as L0 sstables are moved up into > higher levels; however, because LCS only chooses a single volume on which to > write all of the sstables created during a single compaction, the imbalance > is persisted. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
