Abstract
A method for updating a scalable row-store, including: receiving an update to a key within a range of keys in a database table, wherein the database table is distributed across nodes in a cluster of computing devices; and replicating the update over a group of the nodes using a consensus-based replication algorithm, wherein the replication algorithm includes completing the update in response to receiving acknowledgement messages from a majority of the nodes in the group indicating that the majority has received notification of the update.
