Redis

Overview

Redis is an in-memory data store used as a database, cache, message broker, and streaming engine. An agent needs to know it because it underpins real-time applications, vector search, and modern AI pipelines like RAG. Mastering Redis means understanding its commands, data types, modules, and operational tooling.

Mental Model

Redis centers on a single-threaded event loop executing atomic commands against in-memory data structures, extended by modules and client libraries for vectors, streams, and JSON. All operations are key-based and command-driven, with persistence, replication, and clustering layered on top. Start with the command references (redis/docs/latest/commands/redis-7-4-commands/index.md), core data types (redis/docs/latest/develop/data-types/json/path/index.md), and the modules API (redis/docs/latest/develop/reference/modules/index.md) to internalize the architecture.
