In the previous chapters, we introduced the API to develop Apex applications and the library of connectors and transformations that are available out of the box. We also covered the scalability, performance, and fault tolerance of the Apex platform. This chapter is the first of three example project chapters that are dedicated to developing applications that are representative for scenarios and use cases readers may find in various verticals.
This chapter will cover the following topics:
- Streaming ETL and beyond
- The application pattern in a real-world use case
- Analyzing Twitter feed
- Running the application
- The Pub/Sub server
- Grafana Visualization
