Abstract

Examples described herein relate to the synchronization of distributed data files. A host node acquires a lock file including a first nodes-list and a second nodes-list from a central node storing a central copy of data files. A nearest node from the first nodes-list may be identified if the identity of the host node is not indicated in the first nodes-list. The host node obtains an updated portion of a latest version of the data files from the nearest node for synchronizing a local copy. The host node performs modifications on the local copy and updates the lock file by indicating the identity of the host node in the first nodes-list and the second nodes-list. The host node provides a modified portion of the local copy to the central node for synchronizing the central copy with the local copy.

Dependent claims

A method comprising:

acquiring, by a processor-based system, a lock file from a central node storing a central copy of data files associated with a workload, wherein the data files and the workload are distributed across a network of nodes, and wherein the lock file includes a first nodes-list indicating identities of a first set of nodes having a latest version of the data files and a second nodes-list indicating identities of a second set of nodes that have modified the data files;
identifying, by the processor-based system, a nearest node from the first nodes-list responsive to an identity of the processor-based system not matching with the identities indicated in the first nodes-list;
obtaining, by the processor-based system, an updated portion of the latest version of the data files from the nearest node;
synchronizing, by the processor-based system, a local copy of the data files stored on the processor-based system with the latest version using the updated portion;
modifying, by the processor-based system, the local copy of the data files;
updating, by the processor-based system, the lock file by indicating the identity of the processor-based system in the first nodes-list and the second nodes-list;
and
providing, by the processor-based system, a modified portion of the local copy of the data files to the central node, wherein the central copy is synchronized with the local copy of the data files using the modified portion.

A system comprising:

a processing resource;
a machine-readable medium storing instructions that, when executed by the processing resource, cause the processing resource to:
acquire a lock file from a central node storing a central copy of data files associated with a workload, wherein the data files and the workload are distributed across a network of nodes, and wherein the lock file includes a first nodes-list indicating identities of a first set of nodes having a latest version of the data files and a second nodes-list indicating identities of a second set of nodes that have modified the data files;
identify a nearest node from the first nodes-list responsive to an identity of the system not matching with the identities indicated in the first nodes-list;
obtain an updated portion of the latest version of the data files from the nearest node;
synchronize a local copy of the data files stored on the system with the latest version using the updated portion;
modify the local copy of the data files;
update the lock file by indicating the identity of the system in the first nodes-list and the second nodes-list;
and
provide a modified portion of the local copy of the data files to the central node, wherein the central copy is synchronized with the local copy of the data files using the modified portion.

7 more elements

A non-transitory machine-readable medium storing instructions executable by a processing resource, the instructions comprising:

instructions to acquire a lock file from a central node storing a central copy of data files associated with a workload, wherein the data files and the workload are distributed across a network of nodes, and wherein the lock file includes a first nodes-list indicating identities of a first set of nodes having a latest version of the data files and a second nodes-list indicating identities of a second set of nodes that have modified the data files;
instructions to identify a nearest node from the first nodes-list responsive to an identity of a system not matching with the identities indicated in the first nodes-list;
instructions to obtain an updated portion of the latest version of the data files from the nearest node;
instructions to synchronize a local copy of the data files stored on the system with the latest version using the updated portion;
instructions to modify the local copy of the data files;
instructions to update the lock file by indicating the identity of the system in the first nodes-list and the second nodes-list;
and
instructions to provide a modified portion of the local copy of the data files to the central node, wherein the central copy is synchronized with the local copy of the data files using the modified portion.
