Summary

In this chapter, we have applied the concepts of event-time and out-of-order processing to analyze trip data. In only about 500 lines of Java code, we have developed an example application that processes and makes use of real-time ride service data using Apache Apex. Though this is a simplistic application, this example demonstrates how easy it is to set up a real-time ride data processing pipeline using Apache Apex.

In the next chapter, we will work through an example project for an ETL application and constructing a pipeline using SQL.
