@Internal
public interface ExecutableOperation
extends Operation

An ExecutableOperation represents an operation that is executed for its side effects.

This internal interface is proposed to reduce the maintenance of bloated TableEnvironmentImpl.executeInternal(Operation) and improve code readability as execution logic is co-located with the operation definition. Besides, this interface can be used to extend user-defined operation with customized execution logic once this interface is stable and public in the future.
