Summary

In this chapter, we have set up the Storm ensemble. You were introduced to the various building blocks of a Storm topology such as bolts, spouts, and the wiring template—topology builder. We executed and understood the WordCount topology and also made some amendments to it.

In the next chapter, you will read and understand about stream groupings, anchoring, and acking. That will also lead us to reliable and non-reliable mechanisms in the topologies under the Storm framework.
