Abstract
Facilitating checkpoint locks for distributed systems is provided herein. A system can comprise a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can comprise generating an ordered data structure that comprises respective identifications of a group of nodes granted a shared lock for a data file. The group of nodes can comprise a node having a respective identification of the respective identifications. The operations also can comprise, based on a determination that a checkpoint function associated with the shared lock has completed at a node of the group of nodes, removing the respective identification of the node from the ordered data structure. In an example, the shared lock can be a checkpoint application program interface. In another example, the group of nodes can be nodes arranged in a distributed computing hierarchy.
