Interface NonKeyedPartitionStream<T>

All Superinterfaces:

DataStream

All Known Subinterfaces:

NonKeyedPartitionStream.ProcessConfigurableAndNonKeyedPartitionStream<T>

@Experimental
public interface NonKeyedPartitionStream<T>
extends DataStream

This interface represents a kind of partitioned data stream. For this stream, each parallelism is a partition, and the partition to which the data belongs is random.
