Abstract
Instructing a plurality of worker systems in a distributed computing system to perform a checkpoint. Instructing the worker systems includes receiving timing messages from the plurality of worker systems and determining, based on the received timing messages, a common checkpoint time indicating an estimated amount of time to be taken by the plurality of worker systems to write data to the persistent storage for a subsequent checkpoint. The common checkpoint time is used to determine a checkpoint threshold, and responsive to the determined checkpoint threshold, it is determined whether to perform the checkpoint. Responsive to determining to perform the checkpoint, messages are transmitted to the plurality of worker systems instructing the worker systems to perform the checkpoint.
