Edge Delivery Services limits
Edge Delivery Services enforces limits on URL format, index size, sitemap file size, and redirect count.
Document naming and URL format
Section titled “Document naming and URL format”Edge Delivery Services URLs contain only lowercase letters (a-z), numbers (0-9), and hyphens (-). Edge Delivery Services replaces all other characters with a single hyphen and removes leading and trailing hyphens. The full file path must not exceed 900 characters.
For Commerce storefronts, this means:
- Product SKUs in URLs must be lowercase. The Adobe Commerce boilerplate enforces this automatically in the
getProductLink()function. - If you write a custom URL function instead of using
getProductLink(), make sure it applies the same character conversion — lowercase, no special characters, hyphens instead of spaces. - If you are migrating from a platform that used uppercase or special-character SKUs in URLs, add redirects from the old paths to the new lowercase ones. See Redirects for how to set up the redirects spreadsheet.
If your existing URLs contain characters that Edge Delivery Services does not support, add a CDN rewrite rule to normalize them before they reach the origin. See Content delivery network.
Indexing and sitemap size
Section titled “Indexing and sitemap size”| Limit | Value |
|---|---|
| Pages per index | 50,000 |
| URLs per sitemap file | 50,000 |
| Sitemap file size (uncompressed) | 50 MB |
For large catalogs, the 50,000-page index limit means you need multiple query indexes and matching sitemap files. Reference all sitemap files in a sitemap-index.xml file and list each in robots.txt.
If you use the AEM Commerce prerender system for catalogs that exceed 50,000 products, plan to divide the sitemap before launch. Prerender publishes one HTML page per product via the BYOM API and then updates the sitemap via the AEM Admin API. A 60,000-product catalog, for example, requires at least two sitemap files to stay within the 50,000-URL limit.
See Sitemaps for configuration steps.
Redirects
Section titled “Redirects”Each site’s redirect sheet can hold up to 100,000 entries. If you are migrating from a large legacy catalog with many URL changes, plan the redirect list in phases rather than importing all historical redirects at once.
See SEO indexing — redirects for the Commerce-specific redirect guidance.
File upload limits
Section titled “File upload limits”These limits apply to files uploaded through Document Authoring . They affect content authors uploading assets, not storefront code or product data.
| File type | Limit |
|---|---|
Documents (.docx / Google Doc) | 100 MB |
| Spreadsheets | 100,000 rows, 500,000 cells |
| PDFs | 20 MB |
Images (.png, .jpg, .avif) | 20 MB |
Videos (.mp4) | 36 MB |
| SVG | 40 KB |
Favicon (.ico) | 16 KB |
