Скачать или смотреть Redis Architecture UNVEILED: From Simple Cache to Distributed Powerhouse

Redis has evolved from a simple, in-memory key-value cache, initially designed by Salvatore Sanfilippo, into a robust, distributed NoSQL database powering real-time applications globally. This video details Redis's architectural journey, beginning with its core as an ultra-fast in-memory data store supporting essential data structures like strings, hashes, and lists. We explore the introduction of persistence mechanisms, including RDB snapshots and AOF logs, ensuring data durability. The architecture further matured with master-replica replication for redundancy and Redis Sentinel for automatic failover and high availability. Crucially, Redis Cluster emerged to enable horizontal scaling through sharding, distributing data across multiple nodes for petabyte-scale datasets and millions of operations per second. Modern Redis extends its capabilities with Pub/Sub messaging, Geospatial indexing, Streams, and a powerful Modules API. Understand how this evolution positions Redis as a cornerstone for microservices, real-time analytics, and caching layers in cloud environments like AWS ElastiCache, Azure Cache for Redis, and Google Cloud Memorystore, offering unparalleled low-latency performance and scalability.
