Apparatus and Method for Policy Based Rebalancing in a Distributed Document-Oriented Database

摘要

A method includes storing a partition of a distributed document-oriented database in a computer. It is determined whether an assignment policy is unsatisfied, where the assignment policy specifies locations for documents within the distributed document-oriented database. A request for a transfer transaction to move a document from the computer is initiated when the assignment policy is unsatisfied. There is a wait for an indication of a transfer transaction commit or a transfer transaction abort. The transfer transaction is completed in the event of a transfer transaction commit, such that the document is moved from the computer. The transfer transaction is aborted in the event of a transfer transaction abort, such that the document remains at the computer.
