Database Internals: Storage Engines, Transactions, and Recovery
2025-12-21A deep technical walkthrough of how databases store data, ensure correctness, and recover from crashes — covering B-trees, LSM-trees, write-ahead logging, MVCC, isolation levels, and replication.
Inside Vector Databases: Building Retrieval-Augmented Systems that Scale
2025-10-26How modern vector databases ingest, index, and serve embeddings for production retrieval-augmented generation systems without falling over.
Learned Indexes: When Models Replace B‑Trees
2025-10-04A practitioner's guide to learned indexes: how they work, when they beat classic data structures, and what it takes to ship them without getting paged.
Write-Ahead Logging: The Unsung Hero of Database Durability
2024-09-10Dive deep into write-ahead logging (WAL), the technique that lets databases promise durability without sacrificing performance. Learn how WAL works, why it matters, and how modern systems push its limits.

2022-08-17Deep dive into how conflict-free replicated data types underpin realtime editors, whiteboards, and multiplayer apps without sacrificing UX.
B-Trees and LSM-Trees: The Foundations of Modern Storage Engines
2021-07-14An in-depth exploration of B-Trees and LSM-Trees, the two dominant data structures powering databases from PostgreSQL to RocksDB. Learn their trade-offs, internal mechanics, and when to choose each for your workload.
Safe Rollback Strategies for Distributed Databases
2020-11-08A comprehensive guide to designing, executing, and validating rollbacks in distributed database environments without compromising data integrity or customer trust.
Consistent Hashing: Distributing Data Across Dynamic Clusters
2020-03-28A deep dive into consistent hashing, the elegant algorithm that enables scalable distributed systems. Learn how it works, why it matters for databases and caches, and explore modern variations like jump consistent hashing and rendezvous hashing.
