In scenarios where a third-party service impacts page performance, implementing a Circuit Breaker pattern (Option C) can prevent the service from becoming a bottleneck. This pattern helps manage failing service calls by temporarily disabling the service interaction when failures reach a certain threshold, allowing it to recover. Asynchronously loading the data (Option E) ensures the page's primary content loads without delay, while data from the third-party service is fetched in the background, improving the user's perceived performance and page load times.

For optimal job flow concerning data import from a PIM system, the sequence should begin with downloading files globally from an SFTP site, followed by importing data into the B2C Commerce platform:

• First flow: Download files, ensuring all required files are available and ready for import.
• Second flow: Import the storefront catalog which likely has dependencies on the master catalog but is generally smaller and can be updated more rapidly.
• Third flow: Import the master catalog, as it typically contains the foundational data needed for various site functionalities.

This sequence respects data dependency and integrity, ensuring that the storefront reflects the most current and accurate information after all relevant data is imported.

To resolve the issue of incorrect page versions being served across different devices, changing the URL structure to include device-specific parameters can be highly effective. By adding parameters such as 'desktop' or 'mobile' to the URLs:

• The caching mechanism can differentiate between the content for different device types, thus caching and serving the correct version of the page according to the device type specified in the URL.
• This method allows for maintaining existing caching strategies linked to promotions and ensures that SEO is not adversely affected since the content remains the same per device type but is merely served through different URLs.

This approach addresses the core issue without requiring disabling of caching or reengineering existing promotional structures, hence preserving site performance and user experience.
