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

• three types of events
• table-stream duality
• schemas for defining event data
• single writer principle
• features of event broker
• event broker vs message broker

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 7 is all your DEV team should know about Transactions:

• The purpose of transactions
• The concept of transaction: ACID, BASE, single-object and multi-object transactions
• Weak Isolation Levels: Read Committed, Snapshot Isolation and Repeatable Read. Problems and preventing them: Lost Updates, Write Skew and Phantoms
• Serializability and three approaches: Actual Serial Execution, Two-Phase Locking (2PL), Serializable Snapshot Isolation (SSI). Potential problems and performance.
