Indexing is one of the most important performance techniques in databases, yet it’s also one of the most misunderstood. A well-designed index can speed up queries by orders of magnitude, while the wrong index can slow everything down. This visual breaks down 15 powerful indexing techniques every engineer should understand in 2026: 1. B-Tree Balanced disk-based indexing for fast range queries. Used in MySQL, PostgreSQL, Oracle. 2. B+ Tree Optimized for range scans with linked leaf nodes. Used...
