High-Performance Order Storage (HPOS) Compatibility

High-Performance Order Storage (HPOS) is WooCommerce's new database storage for orders to allow effortless scaling for large and high growth stores. Previously known as "Custom Order Tables" HPOS is a solution that provides an easy-to-understand and solid database structure – specifically designed for eCommerce needs. HPOS replaces the default WordPress post-based storage of orders and used dedicated customdatabase tables for data like orders and order addresses instead. This way is more efficient for handling large volumes of orders and eventually improving overall performance.

HPOS is enabled by default for new installations from WooCommerce 8.2 onward. You will need to ensure that all your WordPress extensions are compatible with HPOS before you upgrade to HPOS.

WooCommerce have advised that v2 and v3 of their REST API are compatible with HPOS.

You can check the version of the WooCommerce REST API that your copy of the fmEcommerce Link (WooCommerce Edition) solution is using by looking at the version number included in the WordPress_BaseURL custom function. For example:

url & "/wp-json/wp/v2"

is using v2 of the WooCommerce REST API.
