Abstract
Controlling the direction of replication between cross-region replicated object stores is disclosed. An embodiment includes receiving, from a first storage system by a second storage system, replicated objects of an object store serviced by the first storage system, wherein the first storage system and the second storage system are configured for replication of the object store, and wherein the second storage system is not configured to service requests to modify the object store; determining, by the second storage system, a minimum time interval for taking over service for from the first storage system, such that delaying takeover until reaching the minimum time interval ensures that modification requests received by the first storage system prior to a takeover are correctly ordered as being earlier than subsequent modification requests serviced by the second storage system subsequent to the takeover; identifying, by the second storage system, a trigger initiating a takeover of the service of the object store from the first storage system; and delaying, by the second storage system, a takeover of servicing requests to modify the object store by at least the minimum time interval.
