Asynchronous Epoch Management in Replicated Databases

  title={Asynchronous Epoch Management in Replicated Databases},
  author={Michael Rabinovich and Edward D. Lazowska},
The paper describes a new dynamic protocol for managing replicated data. Like the existing dynamic schemes, our protocol involves reconfiguring the system dynamically to reflect failures and repairs as they occur, so that the data may be kept available for user operations even if only one replica of the data remains accessible. However, in the existing schemes, it is required for the correctness of the protocol that the system reconfiguration either run as a special transaction that competes… CONTINUE READING
