Database Insights

A practical guide to database sharding strategies — hash sharding, range sharding, directory-based sharding — with trade-offs, resharding complexity, and decision criteria for MySQL and PostgreSQL.

Master Redis performance tuning with expert tips on memory optimization, connection pooling, data structures, and caching strategies for high-traffic apps.

PgBouncer multiplexes thousands of application connections onto a small pool of real PostgreSQL server connections — reducing connection overhead without any application code changes.

Deploy PgBouncer in transaction mode for high-concurrency PostgreSQL workloads — config, monitoring, and tuning

A practical guide to Redis use cases in production — cache-aside pattern, sliding window rate limiting, Pub/Sub vs Streams, BRPOP queues with delayed job scheduling, and session storage with persistence configuration.

A comprehensive guide to database connection pooling — comparing PgBouncer, ProxySQL, and HikariCP with configuration examples, pool mode trade-offs, and production sizing recommendations.

Understand MySQL max_connections, thread caching, and connection pool sizing to handle high-concurrency workloads

Deep dive into advanced database indexing strategies including composite indexes, covering indexes, and partial indexes. Optimize query performance with expert indexing techniques.

Choose between ElastiCache Redis and Memcached — data structures, persistence, replication, and cost considerations
