> 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.
> Attached is the execution graph for the same pipeline, before and after the patch.
