Can I store Script API objects in a custom cache?

No, you should only store primitives, arrays, and plain objects. Script API objects are not supported and will fail to store correctly.

What is the recommended pattern for retrieving cached data?

The recommended pattern is using cache.get(key, loader), where the loader function only executes on a cache miss to populate the entry automatically.

How do I define a new cache region?

You define cache regions in a caches.json file within your cartridge and reference that file in your cartridge's package.json under the 'caches' property.

What happens to the cache during code deployment?

Custom caches are automatically cleared whenever a new code version is activated or when any file in the active code version changes.

What is the total memory limit for B2C custom caches?

All custom caches combined share a total memory pool of approximately 20 MB per application server.

Implements application-level caching in Salesforce B2C Commerce using CacheMgr API and JSON-based configurations to optimize storefront performance.

This skill provides specialized guidance for implementing custom caching within Salesforce B2C Commerce (formerly Demandware). It streamlines the process of defining cache regions in JSON, managing entry lifecycles via the CacheMgr Script API, and implementing high-performance patterns like the 'get-with-loader' approach. By mastering site-scoped keys and understanding platform-specific limitations like the 20MB memory cap and 128KB entry limit, developers can significantly reduce server load and improve response times for expensive calculations and external API calls.
