Ling Jin commented on FLINK-15123:
----------------------------------

It seems the issue has no progress for a long time, I would have a try.

 

I am going to walking the code for now, and feedback if I find the clue for how to solve this.

> {{uniqueKeys}} is a kind of constraint, it's unreasonable that {{uniqueKeys}} is a kind of statistic. so we should remove uniqueKeys from {{FlinkStatistic}} in blink planner. Some temporary solutions (e.g. {{RichTableSourceQueryOperation}}) should also be resolved after primaryKey is introduced in {{TableSchema}}
