3.5. Setting up the Cache

Caching can happen in three flavors.

1. Caching a database call or result set
2. Caching a template block
3. Caching an entire page

Cradle uses a cache to deal with a database call or result set. Caching is usually volatile, in that we cannot rely that the data will always exist (persistent) in a cache. But overall using a cache is the fastest way to retrieve data none the less because it does not compute anything to return data. It just looks for a key and returns its value.

Figure 3.5.A. config/services.php

...
'redis-main' => [
    'scheme' => 'tcp',
    'host' => '127.0.0.1',
    'port' => 6379
]
...

INFORMATION: there isn't anything you need to do after a cache is configured. It
should just work.

If you need to truncate data from Redis you can do so with the following commands.
