US Patent 10509675 Dynamic allocation of worker nodes for distributed replication

A set of tasks, associated with a replication job, are generated for replicating from a source to destination site. An initial number of worker nodes are allocated to process the tasks. Each task involves a first type of worker node at the source site, a second type of worker node at the destination site, and includes one or more of copying an object from the source site to the destination site, or deleting an object from the destination site. The replication job is monitored. Based on the monitoring, a number of worker nodes is adjusted from the initial number to a new number, different from the initial number.
