[jira] [Created] (FLINK-31028) Provide different compression methods for per level

Jun Zhang created FLINK-31028:
---------------------------------

             Summary: Provide different compression methods for per level
                 Key: FLINK-31028
                 URL: https://issues.apache.org/jira/browse/FLINK-31028
             Project: Flink
          Issue Type: New Feature
          Components: Table Store
    Affects Versions: table-store-0.3.0
            Reporter: Jun Zhang
             Fix For: table-store-0.4.0


Different compression are provided for different levels.

For level 0 ,because the amount of data in this level is not large, we do not want to use compression in exchange for better write performance . For normal levels, we use lz4 . For the last level, access is generally less and data volume is large. we hope to use gzip to reduce space size.
