-----------------------------------
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.
