Abstract
A controller at a source site generates a set of tasks associated with a replication job. Each task includes one or more of copying an object from the source to destination site, or deleting an object from the destination site. The tasks are placed onto a message queue at the source site. Source worker nodes at the source site retrieve the tasks from the source site message queue for processing in conjunction with destination worker nodes at the destination site. A destination worker node, upon receiving a task from a source worker nodes, places the task onto a message queue at the destination site for retrieval by a backend worker node that handles writing to an object store at the destination site.
