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 5:

• Three algos of replicating
• Single-leader Replication
  • Leaders and Followers
  • Sync and async replication
  • Adding new Followers
