Abstract
A method and system for distributed garbage collection in a pipelined workflow environment comprising a plurality of processing nodes that pass item references to each other. Each node maintains a reference list of local item references and a reference dictionary of remote item references, and periodically synchronizes the reference list with the reference dictionaries of other nodes in the workflow, so that item references are not marked for garbage collection while other processing nodes may still have outstanding references to them.
