--------------------------------------
Summary: Improve recursive application of the field trimming
Key: CALCITE-5061
URL: https://issues.apache.org/jira/browse/CALCITE-5061
Project: Calcite
Issue Type: Improvement
Reporter: Thomas Rebele
Assignee: Thomas Rebele
Fix For: 1.31.0
The RelFieldTrimmer has some shortcomings:
* If the plan contains certain set ops (e.g., UNION(all=false)), even if the
operator needs all fields for the correct result (CALCITE-3399), it may still
make sense to apply the trimming to the children. See CALCITE-5051 for an
example.
* Same applies for a Sort with dynamic parameters in the fetch/offset, and
RepeatUnions
* The makeZeroLiteral logic in trimChildRestore(...) does not work for ARRAY /
Java types.
