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.
Database Connection Pool Exhaustion in Django: Tuning PgBouncer in Transaction Mode
Each Gunicorn worker thread opens an independent PostgreSQL connection, rapidly exhausting max_connections during traffic spikes. Discover how to deploy PgBouncer in transaction mode to serve thousands of concurrent requests with just 20 backend database connections.
Mastering PgBouncer: Connection Pooling & Transaction-Level Sizing
PostgreSQL spawns a dedicated process per connection, exhausting server RAM under high concurrency. Learn how to configure PgBouncer in transaction pooling mode to scale throughput by 5x with minimal resource footprint.
