HPOS

High-Performance Order Storage

Formerly known as Custom Order Tables, HPOS is a WooCommerce feature designed to improve the performance, scalability, and reliability of order data management. Unlike the legacy system that stores order information across multiple WordPress posts and meta tables, HPOS stores orders in dedicated, purpose-built database tables. This modernized architecture reduces query load, speeds up order processing, and enables large stores to scale efficiently without database bottlenecks.

Key Benefits of HPOS:

• Faster Query Performance: Orders are stored in optimized tables, improving speed for order lookups, filtering, and reporting.
• Improved Scalability: Supports high-volume stores by separating critical order data from general post tables.
• Better Data Integrity: Structured schemas reduce the likelihood of data fragmentation or corruption.
• Developer-Friendly: Offers a more predictable, clean data model with improved APIs for customizations and third-party integrations.

HPOS is entirely opt-in and available in WooCommerce 7.1 and above. Many popular extensions, including those built for analytics, CRM syncing, and fulfillment, now offer HPOS compatibility to leverage its performance advantages.
