      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
