rubenada opened a new pull request #2122: URL: https://github.com/apache/calcite/pull/2122
Problem related to the feature CALCITE-3951. A cast operation from a character type to another character type that has a different collator must be evaluated as not monotonic. Currently this is not the case. This has an impact e.g. in SortProjectTransposeRule, since we can incorrectly transpose a sort after a projection than contains such a cast, and we end up with a plan that will return a different result than the original one. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
