Opening Document Stored at Multiple Database Replicas

摘要

A document stored at each of a number of database replicas communicatively connected with a current database replica is desired to be opened. The current database replica is initially opened. The current database replica stores an indicator for the document denoting the database replicas at which the document is stored. A probable time to retrieve the document from each database replica is retrieved from the current database replica. For each database replica, a real-time analysis of network parameters in relation to the database replica is performed based on the probable time retrieved. This analysis yields an updated probable time to retrieve the document from the database replica. The document is thus retrieved from the database replica having the lowest updated probable time.
