-----------------------------------
Summary: Add "Piglet", a subset of Pig Latin on top of Calcite
algebra
Key: CALCITE-785
URL: https://issues.apache.org/jira/browse/CALCITE-785
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
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
