Jonathan Ellis commented on CASSANDRA-5906: ------------------------------------------- Most changes to CompactionTask are cosmetic -- split out to a separate commit? Why would {{metadata.cardinalityEstimator}} be null if we've already checked {{newStatsFile}}? Otherwise +1. > Avoid allocating over-large bloom filters > ----------------------------------------- > > Key: CASSANDRA-5906 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5906 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Jonathan Ellis > Assignee: Yuki Morishita > Fix For: 2.1 > > Attachments: 5906.txt > > > We conservatively estimate the number of partitions post-compaction to be the > total number of partitions pre-compaction. That is, we assume the worst-case > scenario of no partition overlap at all. > This can result in substantial memory wasted in sstables resulting from > highly overlapping compactions. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
