Hi Given a timestamp column, I want to group by every 15 minutes like [1]. How can this be best done with calcite?
Looked at the reference, but answer is not obvious. Thanks Yang [1] http://stackoverflow.com/questions/2793994/group-mysql-query-by-15-min-intervals [2] https://github.com/apache/incubator-calcite/blob/master/doc/REFERENCE.md
