      Description

      When there are multiple incoming edges to the tezprocessor we'll need to be able to tell which alias or tag they belong to.

      In the map case:

      • Potentially multiple MRInputs. Need to map those to aliases/operators

      In the reduce case:

      • Each tag will be represented by a logical input. We need to know which table each input belongs to.

      NO PRECOMMIT TESTS (this is wip for the tez branch)
