Plugin Description
WordPress stores custom post types in the default posts table (typically wp_posts), which is fine for most setups. In the majority of use cases, WordPress sites are not used to store in excess of thousands of posts, and so this sort of setup doesn’t place much additional load on servers.
In cases where the site generates a significant amount of posts across multiple post types though, queries can become very expensive – especially where meta generating plugins such as Advanced Custom Fields are involved. Where a WordPress site is expected to generate thousands of posts (and subsequently, many thousands of rows of post meta) queries can be sped up significantly by splitting out data into separate tables. This plugin splits out data by post type, creating additional tables for each custom post type used. A ‘product’ custom post type for example will have its posts stored in product and its meta in product_meta.
If you are using WordPress a little bit longer, you already know that it is an incredibly versatile platform. With its numerous features and extensions, however, it can sometimes be difficult to keep track of and find the right method for managing your content. This is where the use of WordPress custom post types in separate tables comes in!
By outsourcing your custom post types to separate tables, you can better organize and manage your content. It also allows you to have better control over your database and process queries more quickly and efficiently, which can positively impact the performance of your website.
Moreover, outsourcing custom post types to separate tables can also help improve the security of your website. By separating your content into separate tables, you can prevent malware or hackers from accessing your entire database.
Overall, outsourcing WordPress custom post types to separate tables offers a range of benefits for your website. It can improve the organization and management of your content, optimize the performance of your website, and increase your security. If you want to take your website to the next level, you should consider outsourcing your custom post types to separate tables!

Settings
As soon as you select a Custom Post Type, a new table is created in the database. This table will be used for all entries of this custom post type.
When you migrate the existing entries, the data from the old table is copied to the new table. This process is not reversible.
Backup your database before migrating in case something doesn’t work as you expect.
Implementation
Each new post and meta table is created to the same structure as the WordPress default post and meta tables. This streamlines the storage process and means that WordPress is capable of interpreting the data wherever it would normally use a wp_posts row, e.g. on the admin edit post pages, admin post listing pages, and in the wp-posts functions (e.g. get_post()).
When new posts are created, a row is inserted into the wp_posts table (as normal) and an automatic MySQL trigger is used to copy this data into the new custom table. Queries to the wp_posts and wp_postmeta table are then rewritten to use the custom table, so that all future lookups and updates made by WordPress and its plugins are made to the new tables. The original wp_posts row is retained for lookup purposes, so that we can determine the post type (and therefore custom table) when there is only a post ID available to work with. Since these lookups are (usually) only necessary in the WordPress admin and exclusively use the primary key, they do not significantly increase the load of the request. Additionally, each ID lookup is made a maximum of once per request and the result is cached on a per-request basis.
To minimise unecessary lookups when writing your own queries, specify the post type you are looking for whenever possible. This will allow the plugin to simply parse the table from the query without having to lookup the post type in the wp_posts table.
