  • Patent number: 11714732
    Abstract: Sets of asynchronous replication operations may be tracked to ensure consistency. A tracking service may receive notifications of pending asynchronous replication tasks, and responsive to receiving a manifest indicating a request to be notified upon completion of a set of pending replication asynchronous tasks, matches individual ones of the tasks within the set to tasks indicated as pending. The tracking service may then select a routing table based on a most recent sequence number associated with the set of tasks, determine one of more tracking nodes assigned to track the set of tasks, and send the manifest to each of the tracking nodes. As individual ones of the tasks complete, notifications of completion may be sent to the tracking nodes and an aggregator node aggregates the completion notifications for the set. Once all completion notifications are received, a response to the request indicating completion may be sent.
