Some facts about Apache Storm
Raw
Storm misc
Each spout and bolt can have one or more tasks, each of which corresponds to a thread.
Each topology can run under one or more JVMs. For example, if the combined parallelism (number of tasks) of the topology is 300 and 50
workers are allocated, then each worker will execute 6 tasks (as threads within the worker). Storm tries to spread the tasks evenly
across all the workers.
