- 3. What is platform Cache • Platform Cache is a memory layer that stores Salesforce session and org data for later access. • When you use Platform Cache, your applications can run faster because they store reusable data in memory. • Applications can quickly access this data; they don’t need to duplicate calculations and requests to the database on subsequent transactions.
- 4. What Are the Types of Platform Cache? • There are two types of Platform Cache: org cache and session cache. • Org Cache: Org cache stores org-wide data that anyone in the org can use. Org cache is accessible across sessions, requests, and org users and profiles. • Session Cache: Session cache stores data for an individual user and is tied to that user’s session.
- 5. When Can I Use Platform Cache? • You can use Platform Cache in your code almost anywhere you access the same data over and over. Using cached data improves the performance of your app. • Reused throughout a session, or reused across all users and requests. • Expensive to compute or retrieve • Store Data That Doesn’t Change Often
- 6. What Are Cache Partitions? • Partitions let you allocate cache space to balance usage and performance across apps. • Caching data to designated partitions ensures that the cache space isn’t overwritten by other apps or by less critical data. •
- 8. Store and retrieve values in the org and session cache. • // Get partition • Cache.Org Class • Cache.session Class
- 9. • Cache Key Name Format: Namespace.Partition.Key • // Add cache value to the partition. • Cache.Org.put(Namespace.Partition.Key, value, timestamp(Optional)); • // Retrieve cache value from the partition • String cachedRate = (DataType)orgPart.get('Namespace.Partition.Ke y');
- 10. Platform Cache Considerations • Always handle the cache miss • Data in the cache isn’t encrypted. • Partitions must adhere to the limits within Salesforce. • The session cache can store values up to eight hours. The org cache can store values up to 48 hours.
