Configure Rails redis_cache_store with redis 5

After upgrading to redis 5 in rails 7.1.3, we are facing some issues on trying to replicate same configuration to configure Rails Redis Cache Store we used to have with previous redis 4 version.

This is what we used to have in our production initializer file: We faced 2 issues: 1- cluster is not allowed anymore and suggests to use redis-clustering gem, but we don't know how to innject it here for Rails Redis Cache Store. 2- it seems replica is not allowed anymore so we wonder where this configuration to indicate Redis to use Replicas should be placed.

  config.cache_store = :redis_cache_store, {
    cluster: ["redis://#{ENV['REDIS_CACHE_HOST']}:6379/0"],
    connect_timeout:    5, # Defaults to 20 seconds
    read_timeout:       0.5, # Defaults to 1 second
    write_timeout:      0.5, # Defaults to 1 second
    expires_in: 3.days,
    replica: true,
    pool: {
      size: ENV.fetch('RAILS_MAX_THREADS', 5),
      timeout: 0.5
    }
  }

can you help on replicating this same configuration into the new versions of redis + using the redis-clustering ?

On our tests we have done 2 tries without success: 1- replace cluster by url 2- remove replica config,

but this turned out in dropping down our available MAX CONNECTIONS
