Deprecated: We no longer use this plugin or any result storage at all. That's handled by a local Varnish + CDN.
This Thumbor result storage plugin indexes the creation time of result storage files
using a Redis ZSET. We use this ZSET to delete files older than a certain time frame,
because find performance was too slow for our scale.
The ZSET key is result_storage_creation_time:HOSTNAME where HOSTNAME is the result of hostname on the Thumbor app server
No additional Thumbor Configuration values are used, as it piggy backs off the Redis settings for Storage
