Interesting change, note also #6735. We already have a cache layer so that this isn't called more then once per metadata computation in production mode.

This cache is stored in memory ? File ? How do you make sure it's not stale ?

@soyuka the storage engine of the cache is configurable from laravel's cache config in the file config/cache.php. You can use any cache driver (file, database, redis, memcached, etc) and the second argument to the function [5, 10] basically tells laravel that the cache is only good for 5 seconds and between 5 to 10 seconds period refresh the cached value automatically so it'll only be at max 5 to 10 seconds old.
