Database Insights

Use Spark with JDBC to read from and write to relational databases — partition strategies, predicate pushdown, and write modes

Master MySQL index data structures and optimization strategies. Learn B+ tree internals, index selection, covering indexes, and real-world performance case studies.

A production guide to AWS RDS Proxy — how it works, when to use it, IAM authentication setup, and the connection pool sizing rules that prevent Lambda-induced database overload.

A production guide to TimescaleDB — hypertable setup, automatic chunk management, columnar compression policies, retention policies, continuous aggregates with time_bucket(), and comparison against InfluxDB and Prometheus.

Achieve microsecond latencies at scale with Aerospike. Learn hybrid memory architecture, strong consistency, cross-datacenter replication, and use cases for AdTech and fraud detection.

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.

A deep dive into InnoDB locking — record locks, gap locks, next-key locks, how READ COMMITTED eliminates gap locks, diagnosing deadlocks with SHOW ENGINE INNODB STATUS and performance_schema, and prevention patterns.

MySQL InnoDB supports multiple compression strategies — from ROW_FORMAT=COMPRESSED to transparent page compression using punch holes. Choosing the right approach can cut storage by 40-70% for text-heavy workloads.

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.
