          Description

          Implement a subset of Pig Latin on top of Calcite, mapping it onto Calcite algebra (via RelBuilder) that can then be optimized and executed on any back-end.

          This serves several purposes:

          • Illustrate how to implement a data language on Calcite
          • Clear technical roadblocks so that the real Pig can be implemented on Calcite
          • Strengthen Calcite's support for nested collections and related operations such as cogroup

              Didn't somebody already do pretty much this in the Drill project?

              Or was it that they just tweaked the Pig parser to generate a Drill plan?

              DRILL-82 proposed such a feature but never got past a work-in-progress patch. Seems to be translating a Pig logical plan to a Drill logical plan, and it seems to have copy-pasted Pig's parser.
