Julian Hyde created CALCITE-4220: ------------------------------------ Summary: In SqlToRelConverter, use RelBuilder for creating Aggregate Key: CALCITE-4220 URL: https://issues.apache.org/jira/browse/CALCITE-4220 Project: Calcite Issue Type: Bug Reporter: Julian Hyde
In {{SqlToRelConverter}} use {{RelBuilder}} for creating {{Aggregate}}. Currently we call LogicalAggregate.create directly, and that misses some optimizations. Add config option {{RelBuilder.Config.skipAggOnUniqueKey()}} to disable the optimization that we don't create an {{Aggregate}} if the input is already unique on the GROUP BY key. Without it, some tests in {{SqlToRelConverterTest}} become trivial. Also, that optimization is not valid if there are multiple group sets. (Because we should output multiple rows, and Project only returns one.) So disable it in that case. -- This message was sent by Atlassian Jira (v8.3.4#803005)
