Consistent Hashing ~ Key Concepts in System Design

In this video, we explore the concept of Consistent Hashing, a key technology for load balancing and distributed caching in modern distributed systems. Learn how Consistent Hashing reduces data redistribution when nodes are added or removed, enhancing system stability and efficiency. We cover traditional hashing problems, the basic algorithm of Consistent Hashing, the role of virtual nodes, and simplified Java implementation examples. Discover how this technique is applied in distributed caching, databases, load balancing, and CDNs.

📌 Topics Covered:

• Issues with traditional hashing algorithms
• How Consistent Hashing works
• Virtual Nodes and their benefits
• Simplified Java Implementation
• Applications in distributed systems
