Hi all, I am working on a project to translate SQL into Flink stream API, and want to leverage Calcite to do the parsing, validation and converting to RelNode. So my question is: is there a plan which release will Calcite support the window functions, as introduced in https://calcite.apache.org/docs/stream.html#tumbling-windows?
I know there are CEIL, FLOOR functions, but that seems not expressive enough to express tumbling, sliding, session window syntax. Thanks in advance! Youjun Yuan
