TECHNIQUES FOR FACILITATING PROCESSING CHECKPOINTS BETWEEN COMPUTING DEVICES

Abstract:

The embodiments set forth techniques for facilitating processing checkpoints between computing devices. A method can be performed by at least one first computing device configured to interface with a first server computing device cluster, and include (1) processing objects managed by the first server computing device cluster, where the objects are stored across at least two first partitions associated with the first server computing device cluster, (2) detecting a condition to facilitate a processing checkpoint with at least one second computing device configured to interface with a second server computing device cluster, where the objects are mirrored--but stored differently across at least two second partitions associated with the second server computing device cluster, (3) gathering, from each partition of the at least two first partitions, information associated with a particular number of last-processed objects, and (4) providing the information to the at least one second computing device.
