---------------------------------------
Summary: Add ability to configure RexExecutable behavior on
exceptions
Key: CALCITE-6371
URL: https://issues.apache.org/jira/browse/CALCITE-6371
Project: Calcite
Issue Type: Improvement
Components: core
Affects Versions: 1.36.0
Reporter: Claude Brisson
The current behavior of Calcite's {{RexExecutable}} constant folding class is
to eat all exceptions encountered during reduction. The underlying reason, as
far as I understand it, is that even if Calcite can't reduce an expression,
maybe the evaluation engine will be able to do it. Fair enough.
But it would be useful to be able to chose to let some exceptions go through.
One good example is {{ArithmeticException}} errors. They occur on divisions by
zero, negative logarithms, etc. and we may want to avoid the downstream
evaluation engine to receive such invalid expressions.
