[jira] [Created] (BEAM-8608) Chain DoFns in Flink batch runner when possible.

David Moravek created BEAM-8608:
-----------------------------------

             Summary: Chain DoFns in Flink batch runner when possible.
                 Key: BEAM-8608
                 URL: https://issues.apache.org/jira/browse/BEAM-8608
             Project: Beam
          Issue Type: Improvement
          Components: runner-flink
    Affects Versions: 2.16.0
            Reporter: David Moravek
            Assignee: David Moravek


Right now, in Batch runner, DoFn is executed using MapPartition operator (_FlinkDoFnFunction_), which doesn't have chained driver implementation.

We need to reimplement DoFnFunction with FlatMap to allow chaining.
