When integrating a third-party service that relies on custom objects in B2C Commerce, the primary technical concern is the impact on performance and site stability related to the usage of these objects. Important considerations include:

Custom object quota: Ensuring that the use of custom objects does not exceed platform limits, which could impact performance or even prevent new data from being stored.

Retention or deletion needs: Proper management of custom object lifecycle is crucial to prevent data bloat and maintain database performance, including strategies for timely deletion or archiving of old data.

Addressing these concerns is critical to maintaining the performance and stability of the site while integrating third-party services that require extensive data handling.
