Yes, the UDF annotations are intended to allow better optimizations.
I’m sure there are bugs. If a query with a UDF is not being optimized, log a
bug. The fix is probably at the level of a particular RelOptRule, and therefore
the test case would be in RelOptRulesTest.
But I don’t think that
Hi,
I was wondering if my understanding about UDFs' annotations in
Calcite is correct. For instance, I notice there is a `@Deterministic`
label to specify a deterministic UDF. Then, relevant query rewrite rules
(e.g., ReduceExpressionsRule) need to check the existence of this label
(e.g.,
