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.
High-Density Time-Series Analytics: ClickHouse AggregatingMergeTree and Materialized Views for Billion-Row Telemetry
Relational databases choke when aggregating billions of time-series telemetry events. Harness ClickHouse AggregatingMergeTree and stateful materialized views to serve sub-30ms analytical rollups on billion-row datasets.
Change Data Capture (CDC) at Scale: Streaming PostgreSQL WAL Changes to Redis & Kafka with Debezium and pgoutput
Application-level dual writes fail silently, while table polling destroys database IOPS. Learn how to stream PostgreSQL write-ahead log (WAL) mutations directly to Kafka and Redis using native pgoutput logical replication and Debezium.
PostgreSQL Lock Contention Forensics: Diagnosing Blocked Queries, Lock Queues, and Deadlocks
Sudden connection pool spikes and mysterious query timeouts are almost always caused by invisible PostgreSQL lock queues. Learn how to inspect pg_locks and pg_stat_activity to untangle blocker dependency trees, prevent deadlocks, and implement defensive timeouts.
