Redis Streams

An append-only log data structure (Redis 5.0+) for high-throughput, real-time event syndication and message brokering, featuring Consumer Groups.

Redis Streams (introduced in Redis 5.0) model an append-only log, providing a robust, persistent message broker solution superior to Pub/Sub. The core functionality centers on the `XADD` command to append entries with unique, time-based IDs and `XREAD` for consumption. Crucially, they support Consumer Groups: this advanced feature enables multiple clients to cooperatively process different portions of the same stream, ensuring distributed and reliable message delivery. Use them for high-volume tasks like event sourcing, sensor monitoring, or notification systems.
