Redis

Use it when

• add a low-latency cache queue or coordination primitive to a service
• store expiring keys counters sets and streams with persistence options

What it solves

Not the fit when

• in-memory data structures are not a default system of record

Install

docker run --name redis -p 6379:6379 redis:latest

Invoke

Connect with a supported client, choose explicit key TTL and persistence semantics, and use streams or queues only with idempotent consumers.
