Best Practice
The items per cart limit is a generous 2,000 items. If you know your buyers never approach this limit, you can lower the limit saving data usage for other objects. Consider the same approach for wish list items and wish lists.
All of the cart and wish list data limits can be managed at lower limits. Monitor cart and wish list data usage and if your buyers consistently stay below the limits, you can lower the limits for some or all of the cart and wish list limits. This saves data allowances for other objects.
If you have cart data requirements that exceed the limits, consider the impact on checkout performance and data storage limits.
- Does the additional data push any related data objects beyond their limits?
- Can you offset a data increase by decreasing data requirements in other store functions?
After you assess the impact of a data increase, if you still want to request an increase, contact Support.
