Storm has a grouping strategy called LocalOrShuffleGrouping which will have better performance than ShuffleGrouping in theory. {quote} Local or shuffle grouping: If 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. {quote} This requires context information of tasks in the same Executor. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
