Salesforce Platform Cache is a feature that allows you to store and manage data in-memory, improving the performance of your Salesforce applications. It provides two types of caches: Org Cache and Session Cache. Org Cache is shared across all users in your Salesforce organization, while Session Cache is specific to a single user's session. Here, I'll provide an example of how to use Salesforce Platform Cache with Apex.
Example Scenario: Let's consider a scenario where you have a Salesforce custom object called "Product__c," and you want to cache the product data for better performance.
Step 1: Enable Platform Cache Before you can use Platform Cache, you need to enable it in your Salesforce org. To do this, go to Setup > Quick Find Box > Type "Platform Cache" > Select "Platform Cache."
Step 2: Create a Cache Partition Create a cache partition, which is like a container for storing data in Platform Cache. Each partition has a unique name and can store data with a specific scope (e.g., org-wide or session-specific).
- Go to Setup > Quick Find Box > Type "Platform Cache" > Select "Platform Cache Partitions."
- Create a new partition with a unique name, e.g., "ProductCache."
Step 3: Apex Code for Caching Product Data
Now, you can use Apex code to store and retrieve product data in the Platform Cache.
public class ProductCacheService { // Define the name of the cache partition private static final String CACHE_PARTITION_NAME = 'ProductCache'; // Define a method to get product data from the cache public static List<Product__c> getProducts() { Cache.OrgPartition orgPartition = Cache.Org.getPartition(CACHE_PARTITION_NAME); List<Product__c> products = (List<Product__c>)orgPartition.get('AllProducts'); if (products == null) { // Cache miss, fetch data from the database and cache it products = [SELECT Id, Name, Price__c FROM Product__c]; orgPartition.put('AllProducts', products); } return products; } // Define a method to clear the cached product data public static void clearProductCache() { Cache.OrgPartition orgPartition = Cache.Org.getPartition(CACHE_PARTITION_NAME); orgPartition.remove('AllProducts'); } }
Step 4: Using the Cache in Your Apex Code
Now, you can use the ProductCacheService
in your Apex controllers or classes to retrieve and cache product data:
List<Product__c> products = ProductCacheService.getProducts();
