WordPress plugin for handling legacy redirects in a scalable manner.

This is a no-frills plugin (no UI, for example). Data entry needs to be bulk-loaded via the wp-cli commands provided or custom scripts.

Redirects are stored as a custom post type and use the following fields:

• post_name for the md5 hash of the "from" path or URL.
• we use this column, since it's indexed and queries are super fast.
• we also use an md5 just to simplify the storage.
• post_title to store the non-md5 version of the "from" path.
• one of either:
• post_parent if we're redirect to a post; or
• post_excerpt if we're redirecting to an alternate URL.
