Deep-dives on high-throughput backend architecture, Python & Django performance, real-time Voice AI, and resilient database modeling.
PostgreSQL Index-Only Scans & Covering Indexes: Eliminating Heap Fetches on High-Throughput Read APIs
Eliminate disk I/O bottlenecks in PostgreSQL read APIs by architecting Covering Indexes with the INCLUDE clause and tuning Visibility Maps to guarantee true Index-Only Scans.
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.
Redis Memory Fragmentation & jemalloc Tuning: Diagnosing OOM Kills and Calibrating Active Defragmentation in Production
Redis nodes frequently get killed by the Linux OOM-killer even when used_memory is well below host limits. Learn how to diagnose jemalloc allocator fragmentation and configure active defragmentation safely.
PostgreSQL Declarative Partitioning at 50M Rows/Day: Automating Partition Pruning, Maintenance & Retention with pg_partman
Monolithic tables ingest millions of daily records until index bloat and autovacuum lockups cripple query performance. Master PostgreSQL native range partitioning and automated lifecycle maintenance with pg_partman.
