Immutability

Introduction into Event-driven microservice (EDM) architecture consists of the following topics:

• two topologies
• content of events
• three types of events
• table-stream duality
• schemas for defining event data
• single writer principle
• features of event broker
• event broker vs message broker
• single source of truth principle
• scaling using containers and VMs
• microservice taxes that we should pay

These topics are disclosed in the Chapter 2 of the book we are currently studying:

Earlier the book club of our company has studied excellent book:

Martin Kleppmann - Designing Data-Intensive Applications

This is the best book I have read about building complex scalable software systems. 💪

As usually I prepared an overview and mind-map.

Chapter 11 discovers all aspects about Stream Processing. If your system needs to process some data on-the-fly then your DEV team should learn this info.

• Approaches for transmitting events: Direct messaging, Messaging Systems and Partitioned Logs. Their implementations, pros and cons.
• How to use Streams for databases. Sync databases, Change Data Capture (CDC), Event Sourcing. State, Streams, and Immutability.
• Nuances of Processing Streams. Useful use cases, reasoning about Time, 3 types of stream Joins, Fault Tolerance.
