README

This plugin is a caching extension to S3 Uploads plugin. By default, S3 Uploads, registers s3 stream wrapper that takes care about accessing s3 based filed for operations such as filesize, file_exists and others. This allows developer operate on s3 assets like they were stored locally.

In many cases, S3 Uploads plugin is used to offload images to AWS S3 and data uploaded there is not changing often or at all. In systems with high traffic a continous access to AWS S3 API is not really required and leads to performance degradation (I have observed that sometimes AWS S3 API interaction via S3 Uploads s3 stream wrapper is about 13%-15% of entire execution time).

AWS S3 StreamWrapper class offers caching support by passing to it a class that implements \Aws\CachingInterface. With this support this plugin leverages WordPress object cache to store S3 objects metadata and technically it reduces AWS S3 API interaction to minimum.

This plugin was tested up to: 3.0.0-beta of S3 Uploads
