The Force.com platform
cache layer provides faster performance and better reliability when caching Salesforce session and org data. Specify
what to cache and for how long without using custom objects and settings or overloading a Visualforce view state. The platform
cache improves performance by distributing cache space so that some applications or operations
don’t steal capacity from others.
Because Apex runs in a
multi-tenant environment with cached data living alongside internally cached data, caching
involves minimal disruption to core Salesforce processes.
