Abstract
Techniques for data recovery are provided. The techniques include receiving a notification message sent by a computing node in a distributed graph computing system, where the notification message represents that the corresponding computing node successfully stores current checkpoint data in a persistent memory; generating a checkpoint identifier corresponding to a current checkpoint when determining that all computing nodes in the distributed graph computing system successfully store the current checkpoint data in respective persistent memories; and sending the checkpoint identifier to each computing node, so that each computing node associates the checkpoint identifier with the current checkpoint data stored in the persistent memory, and the associated current checkpoint data is used for data recovery during recovery execution before the corresponding computing node obtains a checkpoint identifier corresponding to a next checkpoint.
