ZhangYao created KUDU-2502: ------------------------------ Summary: Support for undo compaction when keeping long history of data Key: KUDU-2502 URL: https://issues.apache.org/jira/browse/KUDU-2502 Project: Kudu Issue Type: New Feature Reporter: ZhangYao
In some case table will update frequently, but we want to keep long history of data and don't need fine-grained version. If simply increase the undo gc time, there will be a lot of undo deltas which occupy too much disk space and degrade the scan performance. So we can implement an undo compaction opt to compact undo file in compaction interval we set to offset the negative influence. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
