Summary
This chapter has been a whirlwind tour regarding the core concepts of Apache Beam and how to run a basic WordCount pipeline using Apache Apex as a backend. Specifically, we looked at the following topics:
- The technical vision of Beam—any language on any data processing engine
- The main parallel processing patterns of Beam—ParDo and GroupByKey
