> Key: CALCITE-785
> URL: https://issues.apache.org/jira/browse/CALCITE-785
> Project: Calcite
> Issue Type: Bug
> Reporter: Julian Hyde
> Assignee: Julian Hyde
> Fix For: 1.5.0-incubating
>
>
> 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
