Coordinated suspension of replication groups
Abstract:
A target commit sequence number (CSN) to be used to synchronize state information pertaining to an application among nodes of a state replication group (SRG) prior to a suspension of the SRG's operations is identified. Each node stores a respective commit record set of the application. Some number of SRG nodes suspend operations after synchronizing their local commit records up to the CSN. A configuration manager of the SRG verifies that, subsequent to a suspension of operations at the nodes, at least a threshold number of the nodes are available for service and have updated their commit record sets. The configuration manager then re-activates the SRG.
