globalGrouping
Description copied from interface:InputDeclarerThe entire stream goes to a single one of the bolt's tasks. Specifically, it goes to the task with the lowest id.- Specified by:

localOrShuffleGrouping
Description copied from interface:InputDeclarerIf the target bolt has one or more tasks in the same worker process, tuples will be shuffled to just those in-process tasks. Otherwise, this acts like a normal shuffle grouping.- Specified by:
