Hi all, as I try to make progress towards the *full* functionality of MATCH_RECOGNIZE in Calcite I added support for the CLASSIFIER function. The issue can be found in [1] and the PR in [2].
I would kindly ask for a review and some comments as the current implementation works BUT is not elegant and not as Calcite-esque as I would like. I think I should add some kind of Context for MR or so but would really like to get some input. After finishing that I would like to add more and more MR functions, like e.g [3]. Thanks! Julian [1] https://issues.apache.org/jira/browse/CALCITE-3302 [2] https://github.com/apache/calcite/pull/1419 [3] https://issues.apache.org/jira/browse/CALCITE-3294
