----------------------------------
Summary: remove uniqueKeys from FlinkStatistic in blink planner
Key: FLINK-15123
URL: https://issues.apache.org/jira/browse/FLINK-15123
Project: Flink
Issue Type: Improvement
Components: Table SQL / Planner
Reporter: godfrey he
{{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}}
