  • _wc_orders
  • _wc_order_operational_data
  • _wc_order_addresses
  • _wc_orders_meta

What are the New Enhancements that WooCommerce HPOS Has Introduced?

There are three properties that scale the maximum benefits upon bringing in HPOS to WooCommerce, which is highly crucial for eCommerce businesses. They are:

1. Immense Scalability

The increase in the count of customers and their respective orders imposes a lot of load on the database of your store. Thus, it becomes quite difficult for the system to handle the rising order requests and provide them with a reliable experience. Upon integrating HPOS, you will be provided with dedicated tables for storing data such as order details, addresses, and specific indexes.

As a result, the tables will be less busy! Thus, you can expect this feature to enable WooCommerce stores of all sizes or shapes to scale their business to meet their high-end performance requirements without any expert intervention.

2. Heightened Reliability

With HPOS embedded in your WooCommerce store, you can ensure that restoring or implementing the targeted data backup will be simpler. It means you won’t have to worry about losing out on your orders, client details, or inventory numbers, as reliable backups are present within the custom tables.

Moreover, WooCommerce HPOS will also facilitate the implementation of read or write locks to prevent possible race conditions. Such an improvement in the scope of reliability will guarantee a more secure and smoother process of data management for your WooCommerce store.

3. Unmatched Simplicity

With HPOS in place, you won’t have to explore a single large database for locating your WooCommerce entries and the underlying data.

You are independent of the _posts table for finding data or understanding the structure of the table.

Moreover, HPOS also enables you to develop fresh extensions and implement new designs for your products or shops, enhancing your core flexibility with the WooCommerce store. The entire process will be streamlined to add more efficiency and a better user experience.

Custom fields in the WooCommerce orders are considered useful for capturing distinct data. But, they will also slow down the order storage or retrieval aspects. Therefore, to maintain high performance, you must prefer using custom fields only when there is an absolute necessity.

This will ensure optimal performance of the store functions, enabling you to take one step further towards making your store compatible with integrating High-Performance Order Storage WooCommerce.

How to Make Your WooCommerce Store Compatible with HPOS?

Now that you are done with the prerequisites, here are the steps for you to make your WooCommerce store compatible with HPOS:

1. Declate the WooCommerce Store Compatibility with HPOS

To declare your WooCommerce plugin’s compatibility with that of the HPOS, you must add the specific code to the main file, which is:

add_action('before_woocommerce_init', function(){

if ( class_exists( \Automattic\WooCommerce\Utilities\FeaturesUtil::class ) ) {

\Automattic\WooCommerce\Utilities\FeaturesUtil::declare_compatibility( 'custom_order_tables', __FILE__, true );



2. Get or Set an Order and Order Meta

You can then use the WooCommerce API for getting or setting the order alongside the order meta. Make use of the wc_get_order( ) function in place of get_post( ), for retrieving your order data. To give you a better representation, here’s the command alteration that you must do:

// Instead of

$order = get_post( $order_id ); // returns WP_Post object.

// use

$order = wc_get_order( $order_id ); // returns WC_Order object.

For establishing interaction with the metadata, make use of the update_meta_data, delete_meta_data, and add_meta_data methods over the order object. And then follow it up with a save call.

Following that, WooCommerce will identify the active tables and save the required data in various appropriate locations. Here’s a brief elaboration on the command you must implement using the above-stated methods:

// Instead of following update/add/delete methods, use:

update_post_meta( $post_id, $meta_key_1, $meta_value_1 );
add_post_meta( $post_id, $meta_key_2, $meta_value_2 );
delete_post_meta( $post_id, $meta_key_3, $meta_value_3 );
get_post_meta( $post_id, $meta_key_4, true);
// use
$order = wc_get_order( $post_id );
$order->update_meta_data( $meta_key_1, $meta_value_1 );
$order->add_meta_data( $meta_key_2, $meta_value_2 );
$order->delete_meta_data( $meta_key_3, $meta_value_3 );
$order->get_meta( $meta_key_4, true );

Remember, calling the save ( ) method is considered an expensive command, for which you must care to avoid using it more than it is necessary.

3. Validate if the Post is Part of ‘WooCommerce Order’

Use the following code for deciding if the post is part of ‘WooCommerce Order’:

if ( ! function_exists( 'wkwc_is_wc_order' ) ) {
* Check is post WooCommerce order.
* @param int $post_id Post id.
* @return bool $bool True|false.
function wkwc_is_wc_order( $post_id = 0 ) {
$bool = false;
if ( 'shop_order' === OrderUtil::get_order_type( $post_id ) ) {
$bool = true;
return $bool;
