    Description

      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.
