🚀 Feature Proposal

Add support for Redis clusters

Motivation

I tried to use this plugin to connect to a Redis Cluster but I couldn't do it. Is not specified in the docs and I couldn't find any options in the interface so I'm assuming this is not supported but it would be a great feature.

Currently I couldn't find any workaround other than using a custom implementation directly with ioredis.

Example

import { fastifyRedis } from '@fastify/redis';
import type { FastifyInstance } from 'fastify';
import fp from 'fastify-plugin';
export default fp(async function (fastify: FastifyInstance) {
  const { REDIS_HOST, REDIS_PORT } = fastify.getEnvs<EnvSchema>();

fastify.register(fastifyRedis, {
// Something like this would be nice.
clusterOptions: {
    host: REDIS_HOST,
    port: parseInt(REDIS_PORT),
     ...
  });
});

Thanks for the issue!

This is pretty doable, would you like to send a PR?

Sure! I'm gonna try to make some space next week to put a PR, thanks!

I was implementing this and realized that a client can be passed like Redis.Cluster. I tried implementing this plugin again and it worked. Since this is not a blocker and is still pretty easy to do I think we can close this task. Maybe adding a piece of documentation with an example on how to use Clusters could be more useful, does it make sense @gurgunday ?

Yep you can submit a PR that adds a usage example here!
