How to make Doctrine result cache work with Redis on Symfony 3.4

Currently I have this on framework.cache:

app: cache.adapter.redis
default_redis_provider: redis://localhost

doctrine.orm:

metadata_cache_driver: redis
result_cache_driver: redis
query_cache_driver: redis

Sure, it doesn't work, but I have no idea what to even try now. Doing type: pool, pool: cache.app works perfect on Symfony 5/6, but it doesn't do anything on Symfony 3.4, anyone have any ideas?

Sooo 5 mins after posting I have the answer, everything was in prod/doctrine.yaml...

doctrine.orm:

metadata_cache_driver:
    type: service
    id: doctrine.system_cache_provider
query_cache_driver:
    type: service
    id: doctrine.system_cache_provider
result_cache_driver:
    type: service
    id: doctrine.result_cache_provider

framework.cache:

app: cache.adapter.redis
system: cache.adapter.redis
default_redis_provider: redis://localhost

services:

doctrine.result_cache_provider:
    class: Symfony\Component\Cache\DoctrineProvider
    arguments:
        - '@doctrine.result_cache_pool'
doctrine.system_cache_provider:
    class: Symfony\Component\Cache\DoctrineProvider
    arguments:
        - '@doctrine.system_cache_pool'

Bonus edit. How to provide custom namespace:

Create a pool service services:doctrine.cache_pool:

doctrine.cache_pool:
    parent: 'cache.app'
    tags:
        - { name: 'cache.pool', namespace: 'app' }

Then use it in a definition for doctrine.system_cache_provider '@doctrine.system_cache_pool' => '@doctrine.cache_pool'.
