                 Key: FLINK-14662
                 URL: https://issues.apache.org/jira/browse/FLINK-14662
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / Hive, Table SQL / API

Currently UNKNOWN table stats is represented with zeros, which might confuse with KNOWN table stats with exactly 0 row count. 

 

We can use -1 to represent UNKNOWN instead.
