sjwiesman opened a new pull request #10382: [FLINK-15014][state-processor-api] Refactor KeyedStateInputFormat to support multiple types of user functions
URL: https://github.com/apache/flink/pull/10382
 
 
   #  What is the purpose of the change
   
    Refactors the KeyedStateInputFormat to support arbitrary user function types. It now follows the model of Task -> Operator -> Function where the input format is the task, StateReaderOperator is the low-level operator that can be implemented for any function type. In the future this allows us to support reading other low-level encodings such as windows or stateful functions.
