---------------------------------
Summary: More aggregate functions should be marked as splittable
and duplicate-insensitive
Key: CALCITE-4342
URL: https://issues.apache.org/jira/browse/CALCITE-4342
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Liya Fan
Assignee: Liya Fan
As discussed in the mailing list, there are more aggregate functions (e.g.
SINGLE_VALUE, ANY_VALUE) that can be classified as splittable and
duplicate-insensitive. We need to tell the optimizer explicitly about this, so
more optimizations can be applied in various scenarios.
