Abstract
Facilitating object deletion based on delete lock contention in distributed file systems is provided herein. A first node device of a cluster of node devices. The first node device 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 determining whether a contention callback is assigned to an object scheduled to be removed from cache of the first node device. The operations also can comprise, based on the contention callback being assigned to the object, granting a write lock to a second node device of the cluster of node devices and removing from the cache a link to the object. Further, the operations can comprise, based on the contention callback not being assigned to the object, releasing from the cache the link to the object without interactions with other node devices of the cluster of node devices, the other node devices including the second node device and being other than the first node device.
