Support Redis Cluster connection

[AyronK]

Manual

import { createCluster } from "@redis/client";
import createRedisHandler from "@fortedigital/nextjs-cache-handler/redis-strings";
import { withAdapter } from "@fortedigital/nextjs-cache-handler/cluster/adapter";

const { hostname: redisHostName } = new URL(process.env.REDIS_URL);
redis = withAdapter(
  createCluster({
    rootNodes: [{ url: process.env.REDIS_URL }],

    // optional if you use TLS and need to resolve shards' ip to proper hostname
    nodeAddressMap(address) {
      const [_, port] = address.split(":");

      return {
        host: redisHostName,
        port: Number(port),
      };
    },
  })
);

// after using withAdapter you can use redis cluster instance as parameter for createRedisHandler
const redisCacheHandler = createRedisHandler({
  client: redis,
  keyPrefix: CACHE_PREFIX,
});

TODO

• Change to 2.1.0

Hi @AyronK,

It seems that your solution might also be applicable to createSentinel. Am I correct in understanding that?

Thanks!

Perhaps @mwojslaw, I can check as soon as we settle on implementation for cluster as it's not quite ready yet.
