Interface specifying the behavior of a worker vertex. A worker takes a stream of work items to perform. Before it is
assigned its first work item, and after each item has been performed, the worker is asked to describe itself; the
coordinator uses this description to match work items to workers. The act of performing a work item causes a sequence of
output items to be generated
