A cross-region data distribution service enables eventually consistent replication of data objects between geographical regions while maintaining data ordering guarantees. For data replication between two regions, the system leverages a data stream-based replication model where destination region leverages a watch API exposed by origin regions. The origin region watch API provides a resumable data stream for changes happening in the origin region that need to be replicated to destination. The system exposes distribution ability through distribution policies which are global objects that encode the source datasets and desired distribution topology. In order to solve data fanout scalability challenges where same data needs to be replicated to many regions, system leverages caching at origin watch servers. The system maintains data ordering by enforcing ordered replication stream provided by watch servers and using version based conditional optimistic concurrency control writes in destination servers.
