How could this work with redis,memcache, or filecache?

We use this module with the redis module. Just declare it in your services.yml:

services:
  cache.backend.redis:
    class: Drupal\redis\Cache\CacheBackendFactory
    arguments: ['@redis.factory', '@cache_tags.invalidator.checksum', '@serialization.igbinary']

Don't use serialization.igbinary_gz because redis already compresses.

I use the patch of #839444: Make serializer customizable for Cache\DatabaseBackend on any production side!

services:
  cache.backend.redis:
    class: Drupal\redis\Cache\CacheBackendFactory
    arguments: ['@redis.factory', '@cache_tags.invalidator.checksum', '@serialization.igbinary']

  cache.backend.database:
    class: Drupal\Core\Cache\DatabaseBackendFactory
    arguments: ['@database', '@cache_tags.invalidator.checksum', NULL, '@serialization.igbinary_gz']

  cache.backend.memory:
    class: Drupal\Core\Cache\MemoryBackendFactory
    arguments: ['@serialization.igbinary_gz']

  keyvalue.database:
    class: Drupal\Core\KeyValueStore\KeyValueDatabaseFactory
    arguments: ['@serialization.igbinary_gz', '@database']

  keyvalue.expirable.database:
    class: Drupal\Core\KeyValueStore\KeyValueDatabaseExpirableFactory
    arguments: ['@serialization.igbinary_gz', '@database']

"overwriting" services is a core feature. Just put a services.yml in your sites folder.
