Transactional replication is a new enabling technology for service replication. Service replication means that a service runs on a group of processes (service replicas) that work together to execute requests issued by external clients. The characteristic feature of transactional replication is that client requests can be processed on a single replica concurrently as atomic transactions that can read or modify local state. Our goal is to provide an introduction to the transactional replication algorithms. We begin by discussing state machine replication and then present several algorithms that provide full transactional semantics such as deferred update replication and many variants of thereof. Finally, we compare their properties and performance as well as show their strong and weak points.
