Thx a lot for the review and suggestion @wuchong , I have refined the javadoc and updated some limitations. For the `Collation` semantic, as we haven't passed the relevant conditions in the `WITHIN GROUP` clause to the aggregate function at present. I think the `AggregateExpression` could exclude the `OrderExpression` for the moment. After the aggregate function can get the order conditions, I can design the `OrderExpression` and add it back. Look forward for the further progress. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
