public interface ConfigurableStreamPartitioner
StreamPartitionerwhich have to be configured with the maximum parallelism of the stream transformation. The configure method is called by the StreamGraph when adding internal edges.
This interface is required since the stream partitioners are instantiated eagerly. Due to that the maximum parallelism might not have been determined and needs to be set at a stage when the maximum parallelism could have been determined.
