+        content_cache_retention_period: All posts from other servers (including boosts and replies) will be deleted after the specified number of days, without regard to any local user interaction with those posts. This includes posts where a local user has marked it as bookmarks or favorites. Private mentions between users from different instances will also be lost and impossible to restore. Use of this setting is intended for special purpose instances and breaks many user expectations when implemented for general purpose use.

+        media_cache_retention_period: Media files from posts made by remote users are cached on your server. When set to a positive value, media will be deleted after the specified number of days. If the media data is requested after it is deleted, it will be re-downloaded, if the source content is still available. Due to restrictions on how often link preview cards poll third-party sites, it is recommended to set this value to at least 14 days, or link preview cards will not be updated on demand before that time.
         peers_api_enabled: A list of domain names this server has encountered in the fediverse. No data is included here about whether you federate with a given server, just that your server knows about it. This is used by services that collect statistics on federation in a general sense.
