This comprehensive tutorial walks you through Redis Cluster fundamentals, including installation, hash slot sharding, node replication, fault tolerance, configuration files, cluster creation commands, and client testing, all without delving into complex distributed theory.
This article traces MySQL’s architectural evolution—from a single‑instance setup to vertical partitioning, master‑slave replication, horizontal sharding, and finally cloud‑native SaaS—highlighting scalability strategies, sharding routing methods, consistency challenges, and automated scaling techniques for high‑concurrency web applications.
The article introduces SessionDB, a Java‑implemented, LSM‑tree‑based key/value storage engine designed to eliminate sticky sessions by providing high‑throughput, durable, and scalable session data handling, and details its architecture, optimizations, sharding strategy, and benchmark comparisons with BerkeleyDB, LevelDB, and RocksDB.
