Build high-performance Sitecore AI catalogs without creating millions of items

Original: Building High-Performance Product Catalogs in SitecoreAI (XM Cloud) Without Creating Millions of Items

Short summary

Sitecore Experience Edge has hard limits for large catalogs (1,000 items per query, 80 requests/sec). Use a hybrid architecture: product data stays in a commerce/PIM API, Sitecore owns presentation templates, and a dedicated search service (Coveo, Algolia, Sitecore Search) powers discovery. A single wildcard route serves unlimited product URLs, sharing one cached Sitecore response while fetching live data from APIs, avoiding catalog inflation.

  • Experience Edge has hard limits: 1,000 items per query, 80 uncached requests/sec, slow publishes for large catalogs
  • Use hybrid architecture: product data in commerce/PIM API, Sitecore handles presentation templates only
  • Dedicated search service (Coveo/Algolia/Sitecore Search) powers discovery; wildcard route pattern serves unlimited products from one cached layout

Generated with AI, which can make mistakes.
