Abstract
Methods, systems, and computer-readable media for replica group modification in a distributed database are disclosed. One or more stream processors write elements of a data stream to a plurality of replicas in a replica group. A control plane adds an identifier of a new replica to membership metadata for the replica group. The control plane also generates a new version number for the membership metadata that now includes the new replica. The stream processor(s) write new elements of the data stream to the replica group including the new replica. Write requests to the replica group comprise the new version number, and successful writes of the new elements are acknowledged by the replicas based at least in part on the new version number.
