Abstract
A computing system is disclosed for reassigning ownership of a data object between computing nodes. A first computing node having control of a data object transmits a hand-off message indicating control of the data object is being transferred to a second computing node. The first computing node queues requests received at the first computing node relating to the data item. A third computing node that interacts with the data object receives the hand-off message and, in response, delays transmitting requests relating to the data object. The third computing node transmits an acknowledgment to the first computing node. Upon receipt of the acknowledgment, the first computing node communicates to the second computing node to assume ownership and transmits any requests that had queued at the first node. When the second computing node receives the message, it transmits a message claiming control of the data object. In response to the message claiming control, the third computing node transmits its queued requests relating to the data item to the second computing node.
