clone
Description copied from interface:OperationFactory
Clone an operation.This is used for requeueing operations after a server is found to be down.
Note that it returns more than one operation because a multi-get could potentially need to be played against a large number of underlying servers. In this case, there's a separate operation for each, and callback façade to reassemble them. It is left up to the operation pipeline to perform whatever optimization is required to turn these back into multi-gets.
