## Jira Link [CALCITE-7583](https://issues.apache.org/jira/browse/CALCITE-7583) ## Changes Proposed The semantics of UNNEST was wrong according to the SQL standard, and according to all implementations I checked. This PR replaces the "cartesian product" semantics of UNNEST with a "zip and pad" semantics, where multiple collections are zipped and padded to the length of the longest collection The actual implementation parallels in many ways the previous product implementation, it just uses a different Enumerable. The previous implementation FLAT_PRODUCT is now unused, but since it's public I didn't remove it. -- This is an automated message from the Apache Git Service.
