Abstract

A method of dataset replica migration is described. An application session may start on a first compute node. A first replica of the dataset to be accessed by the application session may be located on a second compute node. A second replica of the dataset is created to be co-located with the first compute node. A first data block of the dataset may be requested by the application session. The first data block of the first replica of the dataset may be read from the second compute node, when the second replica does not have a copy of the first data block stored in the second replica. The retrieved first data block may be copied to the second replica. The first data block may be read from the second replica, when the first data block is requested by the application session and is contained in the second replica.
