In this chapter, we have shed some light on how we can define the parallelism of Storm, how we can distribute jobs between multiple nodes, and how we can distribute data between multiple instances of a bolt. The chapter also covered two important features: guaranteed message processing and the tick tuple.
In the next chapter, we are covering the Trident high-level abstraction over Storm. Trident is mostly used to solve the real-time transaction problem, which can't be solved through plain Storm.
