Deep-dives on high-throughput backend architecture, Python & Django performance, real-time Voice AI, and resilient database modeling.
Horizontal Database Sharding at Scale: Citus Distributed Tables, Distributed Transactions, and Partition-Wise Joins
When a single PostgreSQL primary reaches write saturation and storage limits, Citus transforms PostgreSQL into a distributed cluster. Master shard keys, 2PC distributed transactions, and co-located joins.
SQLite in High-Concurrency Server Production: WAL2 Mode, Memory-Mapped I/O (mmap), and 15,000+ Reads/Sec on the Edge
Dismissed as an embedded toy, modern SQLite can power blazing-fast edge backends and microservices. Discover WAL2 checkpoints, mmap_size, PRAGMA connection pooling, and multi-reader concurrency patterns.
PostgreSQL TOAST Internals & Large JSONB Bloat: Eliminating Compression Overhead and Out-of-Line Storage Traps
High-volume JSONB and text columns trigger PostgreSQL TOAST tables, silently degrading read throughput and inflating disk I/O. Master storage strategies, LZ4 vs pglz compression, and out-of-line detoasting tuning.
PostgreSQL Query Planner Internals: Calibrating Cost Factors, Work Memory, and SSD Random Page Penalties
Default PostgreSQL configuration parameters were calibrated decades ago for spinning magnetic hard disks. Learn how the cost-based optimizer calculates query plans and how to tune random_page_cost and work_mem for modern NVMe SSD storage.
