Hi @huawei-flink, I did not say that we need to move the state out of the
code-gen'd function. We can and should leave the PR as it is.
However, we cannot use this code for distinct group window aggregates but
only for distinct over aggregates once they are supported in the API.
> Add support for DISTINCT into Code Generated Aggregations
