Object caching with Bedrock (and Trellis) using Redis
What is object caching
While nginx microcaching already solves page caching (as of static, rarely changing WordPress pages), the performance for dynamically generated pages (like WooCommerce shop pages and admin backend in general) can benefit greatly from additionally using an object cache. Object caching allows an application (in this case WordPress with its plugins, theme, etc.) to store prepared objects (mostly database queries) in a database and quickly retrieve them, therefore improving the performance of dynamic page generation. Object caching is (usually) transparent, which means that it shouldn't be noticeable by users and developers (except for the performance improvements of course).
