Trident Introduction

In the previous chapters, we covered the architecture of Storm, its topology, bolts, spouts, tuples, and so on. In this chapter, we are covering Trident, which is a high-level abstraction over Storm.

We are covering the following points in this chapter:

• Introducing Trident
• Understanding Trident's data model
• Writing Trident functions, filters, and projections
• Trident repartitioning operations
• Trident aggregators
• When to use Trident
