[jira] [Created] (FLINK-26346) Add statistics collecting to sst files

Caizhi Weng created FLINK-26346:
-----------------------------------

             Summary: Add statistics collecting to sst files
                 Key: FLINK-26346
                 URL: https://issues.apache.org/jira/browse/FLINK-26346
             Project: Flink
          Issue Type: Sub-task
          Components: Table Store
    Affects Versions: 0.1.0
            Reporter: Caizhi Weng


Currently field statistics are not collected in sst files. With statistics we can do filter and other operations with better performance.

Some formats like orc already record statistics into file headers, so for these special formats we just need to read them directly from files. For others, however, we need to collect the statistics by hand.
