Configure caching for remote storage

Remote storage provides a cache layer for external API calls. The caching is based on the Flysystem caching solution, which provides cache adapters. Remote storage includes the following cache types:

• Memory cache—Memory cache is enabled by default and provides per-request cache.
• Redis cache—Redis cache is a persistent cache that is stored in Redis and requires an active Redis service with additional configuration.

Set up persistent Redis cache

To use Redis cache with predis/predis extension:

1. Add the predis/predis extension to the require section of your composer.json file.

   1
   composer require predis/predis
   

2. Use the following example to add a configuration to the app/etc/env.php file.
