Abstract: A geographically distributed data store including a number of geographically distributed regions may be implemented using replication groups that include multiple regions configured according to replication criteria. First tier replication of particular changes to data stored in the distributed data store may be performed in compliance with the replication criteria, where management of replication state is performed with respect to replication across the replication groups. Independent of the first tier replication, individual replication groups may implement second tier replication of changes to data where management of replication state is performed with respect to replication within the particular replication group. Replication group configuration may be determined using the replication criteria which may include thresholds for replication resource utilization, replication latency and utilization of data change logs.
