-------------------------------------

Hello [~Underwood] , are you trying to implement the logic by a data stream job? I think the Z letter cannot be incremented by every record because it's not a global variable in the flink job.

> For example, I'm counting letters. Each letter of A ~ Y corresponds to a partition, and each partition records the number of times their letters appear, but the letter of Z needs to be counted by each partition, that is, in a stream, A ~ Y needs hash partition and Z needs broadcast partition. Is there any method to realize this?
> I want to use partitioncustom, but it seems that it can only be sent to one partition.
