Abstract
Techniques are provided for moving an item from one item server to another item server in a distributed storage system, using a location service, APIs, and item states. There are three parties that transact with each other: a source item server, a destination item server, and a location service. Each item stored at the source has a move status, e.g., 'stationary', 'source attempting transfer', “destination accepting transfer”, or “destination attempting transfer”. Similarly, each item stored at the destination also has a move status, e.g., “stationary”, “source attempting transfer”, “destination accepting transfer”, or “destination attempting transfer”. The location service desirably has an entry for every item stored by the storage system. An item's entry may comprise the item's current location (e.g., an identifier of an item server) together with a state, such as “stable” or “attempting transfer”.
