[jira] [Created] (FLINK-11110) Support pipeline stage type inference

Weihua Jiang created FLINK-11110:
------------------------------------

             Summary: Support pipeline stage type inference
                 Key: FLINK-11110
                 URL: https://issues.apache.org/jira/browse/FLINK-11110
             Project: Flink
          Issue Type: Sub-task
            Reporter: Weihua Jiang


It is important for any AI platform to have the type inference for each stage and pipeline. We can have some help here for ML pipeline to support such kind of type inference (static type and compatibility check) for each stage and pipeline. 

 

That is, each stage shall declare which kind of input type and shape it can accept and it will output. Then, the framework will perform compatibility check to see whether they are compatible or not.
