System and methods are described for a server computing node including a processing device and a memory device. The processing device executes instructions stored in the memory device to receive a request to update a data object in a shared storage of a distributed computing system; get a current version identifier (ID) of the data object; get the data object identified by the current version ID from the shared storage; update the data object; write the updated data object to shared storage using a unique new version ID; and cause the conditional update of the current version ID of the data object to the new version ID.
