Overview

Redis keeps jobs in memory, so they are added and taken quickly. The adapter works with anything that speaks the Redis protocol: Redis, Valkey, Dragonfly, Amazon ElastiCache and Upstash. It is the only adapter that lists its jobs on the Queue page; the others show counts only. No PHP extension is needed. The adapter uses the redis extension when it is loaded, which is faster, and the built-in Predis client otherwise, so it also works on shared hosting with a hosted Redis such as Upstash.

​
Configuration

1

Get a Redis server

Use a Redis on your server, or create a hosted database. On Upstash, create a Redis database and copy its connection URL, which looks like rediss://default:PASSWORD@HOST.upstash.io:6379.
2

Enter the connection

Go to Settings → System → Queue adapters → Redis and paste the Connection URL. A URL starting with rediss:// uses TLS, which hosted services need.To type the details in instead, click Enter host, port and password separately, then fill in Host and port, Username, Password and Database, and turn on Use TLS if your server needs it. Any URL already entered is split into these fields, and saving builds the URL from them. Use a connection URL instead switches back.
3

Test and enable

Turn on Status and press Save changes. Saving tests the connection first, and shows the service’s error if it fails. Then choose Redis on the Queue page.

​
Settings

Keys are grouped under one hash tag ({aikeedo}:…), so the adapter also works on a Redis Cluster.
