What is Redis?
Redis keeps data structures (strings, hashes, sorted sets, streams) in memory with sub-millisecond access, making it the standard choice for caching, rate limiting, pub/sub, and job queues. After a licensing controversy, Redis returned to open source under AGPLv3 in 2025; Valkey continues as a BSD-licensed fork.
