Abstract
One or more publish control-plane components (PCCs) of a data store determine that operation records (ORs) indicative of operations performed on a data object are to be published via a durable log publisher. The PCCs assign, for a particular publish session of one or more publish sessions established for the data object, an OR submitter to transmit ORs associated with the data object from a designated buffer to the durable log publisher. The OR submitter transmits a particular OR to the publisher, and the publisher replicates the particular OR at nodes of a DAG (directed acyclic graph). Contents of the OR are provided by the publisher in response to a read request.
