A system and method for supporting multi-version remote function execution control in a distributed computing environment is provided. Remote functions are provided with a version identifier which uniquely identifies the version of the remote function. The version identifier can be a digest of the class definition of the remote function. The version identifier is used by an executor and/or class loader to ensure execution of correct class versions when on a node in a distributed computing environment. The definitive identification of class versions also provides for conditional transmission of class definition thereby reducing communication overhead for distribution of remote functions.

System and method for multi-version remote function execution control in a distributed computing environment

A system and method supports dynamic deployment of executable code in a distributed computing environment. A server node in the distributed computing environment can receive a class definition from a client to execute, and generate and load into memory an instance of a class using said class definition without restarting or redeploying the server node. The class definition can define a new or updated class otherwise unavailable to the server node. Classes are identified with unique class identities which enables determination of whether a class is new or updated. The class identity can be used to determine the need for transmitting a class definition to a server node and also to ensure that a correct version of a class in implemented. In a particular case the new or updated class definition implements a lambda expression.
