Abstract: Methods, systems, and computer-readable media for delivery of log records to stateless clients are disclosed. A record delivery system receives, from a client, a first request to read from a persistent log comprising an ordered sequence of records. The first request is associated with a receiver session. The system sends a first set of records to the client and stores a data structure indicating that the first set of records was sent to the client in the receiver session. The system receives, from the client, a second request to read from the persistent log in the receiver session. Based at least in part on the data structure, the system determines a second set of one or more records in the persistent log. The system sends the second set of records to the client.
