Use the RedisAdapter directly: https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Cache/Adapter/RedisAdapter.php

I use SNCRedis for spooling mail and in some other places for non-caching purposes (locking and spooling) as well. So it would be nice to reuse the same connection. I managed to do this using the following config:

framework:
    cache:
        app: cache.adapter.redis
        default_redis_provider: snc_redis.default

Another advantage of this setup is that cache calls using the cache component will be included in the SNCRedis-item in developer toolbar. I thought it might be worth mentioning this possibility in the documentation.

@Sander-Toonen is this configuration working? I am working exactly on the same thing and don't have a clue in how to achieve this, could you help with some examples and setup from your experience?

@reypm You can refer here: https://github.com/symfony/framework-bundle/blob/fc11aa3f2c0170efd354b4e3badaf1fb6455327b/Tests/Functional/app/CachePools/redis_config.yml

I believe what @Sander-Toonen gave above is correct. See https://github.com/symfony/symfony/blob/4aa9508ae324cfc7fb02f5b0a3328afbe2768236/src/Symfony/Bundle/FrameworkBundle/DependencyInjection/Compiler/CachePoolPass.php for how it works.

@teohhanhui yes but even though the docs here are really poor. At least a working example should be enough can you provide some of them?

@reypm The above snippet in @Sander-Toonen's comment is a working example. It changes the app cache pool to use Redis. That's the cache pool provided by the FrameworkBundle out of the box for you to use in your app code. (There's also a system cache pool which is used by the FrameworkBundle for the various Symfony components.)

If you are unsure of how to utilize the cache, please see https://symfony.com/doc/current/components/cache.html and http://www.php-fig.org/psr/psr-6/

Anyway it should be a good idea that some kind of mention of Symfony 3 Cache Component was put somewhere here in docs. Right now it's a bit confusing how SncRedisBundle releates to this new Cache Component, how they can work together and if there is even still a need to use SncRedisBundle for new applications if there is new component handling this out of the box.

PRs better explaining the current state of affairs welcome 😄

I think #291 (comment) is already enough to be added on the documentation of this bundle. 👍

PR integrating it in a nice way welcome 😁 Kinda stoked on time myself.
