KeyDB — Overview and Practical Guide

Limitations & considerations

// Inside the KeyDB command execution engine (e.g., processCommand)

1. Download and Install: Download and install KeyDB on your local machine or server.
2. Create a Database: Create a new KeyDB database and start storing data using the key-value pair.
3. Choose a Client: Choose a KeyDB client library for your programming language of choice.
4. Start Building: Start building your application using KeyDB as the data storage solution.

• Data Model: Key-value pair
• Data Types: String, Hash, List, Set, Sorted Set
• Persistence: Supports data persistence to disk
• Replication: Supports data replication for high availability
• Multi-Threading: Supports multi-threading for high-performance
• Scalability: Designed to scale horizontally

• KeyDB runs on multiple cores via an event-driven, sharded thread model where each thread handles a subset of keys.
• No global lock for most operations → linear scalability with CPU cores.
• Threads share memory but each has its own event loop (based on epoll/kqueue).
