To define a future method, simply annotate it with the future annotation, as follows. Salesforce provides a series of asynchronous processing methods for Apex to allow developers to produce longer-running and more complex Apex code. The specified parameters must be primitive data types, arrays of primitive data types, or collections of primitive data types. future , the method executes when Salesforce has available resources. You can call a future method for executing long-running operations, such as callouts to external Web services or any operation you'd like to run in its own thread, on its own time.
