-----------------------------------------
Summary: Calcite planner: Correct outer-join value transfer
registration
Key: IMPALA-15469
URL: https://issues.apache.org/jira/browse/IMPALA-15469
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Aleksandr Efimov
Assignee: Aleksandr Efimov
On master 2f022a5ca0fc99670bcf197a1f89016cdf78d114, Calcite loses safe value
transfer through a grouped RHS of LEFT JOIN, allows forbidden directions for
RIGHT/FULL JOIN, and mutates metadata shared with child joins. Direct compiler
tests bypass fallback: OriginalPlanner passes all 11 cases, Calcite fails 8.
In the LEFT-aggregate-plus-INNER case, the fact scan also misses the upper join
runtime filter. The fix uses the aggregate result tuple and clause-local join
metadata with the correct operator and nullable tuple IDs.
Native Java build and 23 Maven tests pass, including the generated-filter
assertion. Engine result parity, performance and full upstream precommit remain
untested. Related: IMPALA-14105 and IMPALA-13587.
