             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.
