                 Key: DRILL-3841
                 URL: https://issues.apache.org/jira/browse/DRILL-3841

          Issue Type: Sub-task
          Components: Execution - Codegen, Execution - Data Types
            Reporter: Jacques Nadeau


To correctly model movement of intermediate workspace values for two-phase 
aggregate UDAFs, we need to implement a way to define a ephemeral data type 
that can be treated as a single atom from the operator standpoint.
