Abstract
A method of migrating data entries stored in a distributed data store from a source memory device of the data store to a target memory device of the data store. The method comprises locking a data entry in the source memory with a soft locking mechanism by an application executing on a computer system, reading the data entry in the source memory by the application, cloning the data entry in a shadow journal in the target memory by the application, launching a plurality of alias redirection threads by the application, where each remaps one of a plurality of aliases of the data entry from referencing the location of the data entry in the source memory to referencing the location of the data entry in the target memory, and committing the data entry in the shadow journal to the target memory by the application.
