Abstract: One or more computing nodes located in a first region may maintain a first collection of data items. A second set of one or more computing nodes in a second region may maintain a collection of data items that is at least a partial replica of the first collection. Notifications of changes to the first collection may be transmitted, via a broadcast communications channel, to a replication module, which may be included in a client application. The replication module may transmit requests to update the second collection of data based on changes to the first collection. Conflicts may be resolved through a last-write wins policy.
