Hello everyone, I am not sure if anyone else (apart from my downstream project) is using RepeatUnion and associated operators to build recursive unions (experimental feature implemented via [1]), but just in case: I am considering a patch to fix some known issues ([2] & [3]) on the current implementation. This patch might potentially break the current contract of this operator, so if you think that you may be impacted by this change, please do not hesitate to take a look at the PR [4] and contribute to the discussion in there.
Thanks and best regards, Ruben [1] https://issues.apache.org/jira/browse/CALCITE-2812 [2] https://issues.apache.org/jira/browse/CALCITE-3673 [3] https://issues.apache.org/jira/browse/CALCITE-4054 [4] https://github.com/apache/calcite/pull/2690
