Hola crack! En mi opinión, sería interesante completar la configuración con $settings['cache_prefix'] , interesante en el caso de compartir la misma instancia de Redis con varios sitios.

@apermuy gracias por el aviso, añadido: https://gist.github.com/keopx/7d5fe4d7a890c792c43bb79cf56718e0#file-settings-local-php-L61

thanks very much for the config！

and one question

is chainedfast a core function of D8? I only found there is a D7 module at https://www.drupal.org/project/chained_fast

@keopx para habilitar las conexiones persistentes:
$settings['redis.connection']['persistent'] = TRUE;

@vifito gracias, añadido: https://gist.github.com/keopx/7d5fe4d7a890c792c43bb79cf56718e0#file-settings-local-php-L15

@keopx para seleccionar la db de redis que quieras (por defecto usa la 0):
$settings['redis.connection']['base'] = 1;

Gracias @luisbunuel . Estaba teniendo errores con un despliegue en Drupal 8, y en concreto con el módulo de Redis para así poder conectarme a una bbdd de Redis en AWS (ElastiCache). Una vez le establecí el valor indicado con el ID de la base de datos en concreto, ya realizó la conexión existosamente. Dejo aquí un ejemplo por si le puede servir a más gente:

  $settings['redis.connection']['interface'] = 'PhpRedis';
  $settings['redis.connection']['host']      = 'tcp://servidor_ejemplo.hiegiu3ctw.0002.usw1.cache.amazonaws.com';
  $settings['redis.connection']['port']      = '6379';
  $settings['redis.connection']['base']      = '15';
