Event Scheduling

Basic Producer and Consumer (BPC) is a simple pattern for creating microservices. It forms the foundation of stateless and stateful services.

You can use it for:

• interfacing layer between event streams and legacy systems
• leverage external stream processing systems to augment capabilities.

But it requires your extra effort for:

• simple state materialization
• event scheduling
• timestamp-based decision making

All of these is disclosed in the Chapter 10 of the book we are currently studying:

Deterministic Stream Processing is a foundation for building scalable event-driven systems. The lack of determinism can be very painful for the business (imagine lost financial transactions, missed alerts, wrong data aggregation).

There are certain tips and tricks on how to implement determinism. Keywords are:

• Timestamps
• Event Scheduling
• Watermarks
• Stream Time

Also you should understand the nature of Out-of-Order and Late-Arriving Events. And strategies for handling them.

Also need to support reprocessing.
