> This issue only involves simple stream group aggregate, complex group aggregate(including
GROUP SETS and DISTINCT) will also be finished in new issue.
> A logical aggregate will be converted to StreamExecGroupAggregate, and a StreamExecGroupAggregate
will be written to two-stage aggregates (StreamExecLocalGroupAggregate and StreamExecGlobalGroupAggregate)
if mini-batch is enabled and all aggregate functions are mergeable.
> Retraction rules will also be ported, because multiple level aggregates will produce
retraction message.
