Abstract
Techniques are described for enabling a database service to provide a zonal consistency model for read and write operations involving database tables replicated across a plurality of availability zones of a cloud provider network according to some embodiments. A database service routes zonally consistent operations to request routers and storage nodes that are located in a same availability zone as the client device from which the request originates. For example, in contrast to standard write operations and strongly consistent read operations, which are processed by a leader storage node that may be located in a different availability zone than the originating request, zonally consistent operations can be processed by any storage node and, in particular, by a storage node in a same availability zone as the originating client device.
