Thanks for reply. I got it.
> Unable to trigger onEventTime() when using the async state API in
> RowTimeSortOperator

> Key: FLINK-36942
> URL: https://issues.apache.org/jira/browse/FLINK-36942
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Runtime
> Affects Versions: 2.0.0
> Reporter: Wang Qilong
> Priority: Major
>
> When I use the async state API in RowTimeSortOperator and inherit it from
> AbstractAsyncStateStreamOperator, I cannot trigger onEventTime() when the
> timer expires.
> Regarding how to reproduce:
> In
> [AsyncStateRowTimeSortOperator|https://github.com/Au-Miner/flink/tree/RowTimeSortOperator]
> and execute the tests in RowTimestamportOperatorTest.
> I think this is a very strange bug because it can be triggered smoothly in
> [AsyncStateWindowJoinOperator|https://github.com/apache/flink/pull/25815],
> but cannot be implemented in RowTimestamportOperator.
