> Key: FLINK-17137

> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Planner, Table SQL / Runtime
> Reporter: Benchao Li
> Priority: Major
>
> Currently only regular aggregate and deduplicate support mini batch. WindowOperator is a very frequently used operator in Flink, it's very helpful to support mini batch for it.
