Xiaolin Ha created HBASE-27323: ---------------------------------- Summary: Support to take the initiative to compact cold large files and compression diff hfiles after changing storefile compression algrithm Key: HBASE-27323 URL: https://issues.apache.org/jira/browse/HBASE-27323 Project: HBase Issue Type: Improvement Components: Compaction Affects Versions: 2.4.13, 3.0.0-alpha-3 Reporter: Xiaolin Ha Fix For: 2.6.0, 3.0.0-alpha-4
We can set switch to enable this feature, to make the compression algrithm changes be applied to all the existing store files, especially when we make a lower space usage compression algrithm change, e.g. from LZO to ZSTD can save more than 30% spaces. All the compaction policies should support this feature. -- This message was sent by Atlassian Jira (v8.20.10#820010)
