Grant Henke updated KUDU-859: ----------------------------- Target Version/s: (was: 1.5.0) > Actively remove data and deltas for deleted columns > --------------------------------------------------- > > Key: KUDU-859 > URL: https://issues.apache.org/jira/browse/KUDU-859 > Project: Kudu > Issue Type: Improvement > Components: tablet > Affects Versions: Private Beta > Reporter: Todd Lipcon > Priority: Major > > Currently, we only remove data blocks for deleted columns when we run a > compaction. If a table is already fully compacted, this won't happen at all. > In most cases, it will happen very slowly. > We should add some kind of in-the-background operation which removes the > CFiles corresponding to deleted columns, and modify the delta compaction code > paths to actually drop delta data for deleted columns. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
