      Description

      FLINK-19582 introduces a basic sort-merge based blocking shuffle implementation. We can further optimize it based on the approaches proposed in https://docs.google.com/document/d/1mpekX6aAHJhBsQ0pS9MxDiFQjHQIuaJH0GAQHh0GlJ0/edit?usp=sharing.

      This is the umbrella ticket for the optimizations.
