> We can reproduce this issue through adding the following code to {{GroupWindowITCase#testWindowAggregateOnUpsertSource}} method:
> {code:java}
>     tEnv.getConfig.getConfiguration.setBoolean(
>       ExecutionConfigOptions.TABLE_EXEC_MINIBATCH_ENABLED, true)
>     tEnv.getConfig.getConfiguration.set(
>       ExecutionConfigOptions.TABLE_EXEC_MINIBATCH_ALLOW_LATENCY, Duration.ofSeconds(1))
>     tEnv.getConfig.getConfiguration.setLong(
>       ExecutionConfigOptions.TABLE_EXEC_MINIBATCH_SIZE, 10L)
> {code}
> The reason is the group window without any data (the data may be retracted) should not send any record.
