DSE Advanced Replication architecture
Multiple clusters are combined into a federated system with unidirectional streams. With DSE Advanced Replication, clusters have two- or three-tier hub-and-spoke topology.
Multiple clusters are combined into a federated system with unidirectional streams. With DSE
Advanced Replication, clusters have two- or three-tier hub-and-spoke topology. This image
shows two unidirectional streams linking an edge cluster to a central hub cluster.
All of the data with centralized management and analytics is stored in the database hub
clusters, with a DataStax Enterprise edge cluster in each remote location. This cross-cluster
data migration supports selected data replication strategies. All of the data can be stored
centrally, with only a slice of the data stored in each remote location. This image shows a
more complex architecture with multiple types of edge use cases that are linked to a
centralized cluster of three datacenters. The edge clusters can experience disconnections from
the network and periodically send one-way updates to the hub clusters.
