---------------------------------

             Summary: Support JSON functions provides by calcite for blink planner
                 Key: FLINK-16185
                 URL: https://issues.apache.org/jira/browse/FLINK-16185
             Project: Flink
          Issue Type: New Feature
          Components: Table SQL / API
            Reporter: Zili Chen
             Fix For: 1.11.0


Calcite 1.20 provides several built-in JSON functions(listed below). In order to enrich our builtin UDFs and according to our internal user experiences I'd propose to support those functions for blink planner.
