How to find out if your WooCommerce store uses HPOS (High-Performance Order Storage)
In your WordPress dashboard navigate to:
WooCommerce > Settings > Advanced > Features
Under the "Features" list, locate Order data storage to see if "High-performance order storage" is selected.
In case you're curious, here is how to understand your exact configuration:
- Active Status: If "High-performance order storage" is the authoritative setting, your site is actively using HPOS.Compatibility Mode
- If you see "Enable compatibility mode" checked, HPOS is running but actively syncing your orders back to the legacy WordPress posts table to maintain support for older plugins.
- Legacy Mode: If "WordPress posts tables" is selected as authoritative, you are not using HPOS.
If your store was created after October 2023, HPOS is likely enabled by default.
