Cache Manager for Apex: Quick Start

For Apex developers, the CacheManager class has several methods that can be used to cache data in 1 of the 3 supported cache types - transaction, organization platform cache, and session platform cache. Each cache type implements the interface CacheManager.Cacheable - regardless of which cache type you choose, the way you interact with each cache type is consistent.

// This will cache a Map<String, Group> that contains all queues in the current org (if the data has not been cached)
// or it will return the cached version of the data (if the data has previously been cached)
public static Map<String, Group> getQueues() {
    String cacheKey = 'queues';
    Map<String, Group> queueDeveloperNameToQueueGroup;
    if (CacheManager.getOrganization().contains(cacheKey)) {
        queueDeveloperNameToQueueGroup = (Map<String, Group>) CacheManager.getOrganization().get(cacheKey);
    } else {
        queueDeveloperNameToQueueGroup = new Map<String, Group>();
        for (Group queueGroup : [SELECT Id, DeveloperName, Email, Name FROM Group WHERE Type = 'Queue']) {
            queueDeveloperNameToQueueGroup.put(queueGroup.DeveloperName, queueGroup);
        }
        CacheManager.getOrganization().put(cacheKey, queueDeveloperNameToQueueGroup);
    }
    return queueDeveloperNameToQueueGroup;
}
