1. A method for managing a transaction log, the log representing a sequence of transactions in a network of connectable computers, each transaction containing at least one update targeting a target database object in a distributed hierarchical target database that contains convergently consistent replicas residing on separate computers in the network, the method comprising the steps of:

  • identifying an incompressible sequence of updates in the transaction log;

    ruling out those updates in the incompressible sequence as candidates for removal from the transaction log;

    identifying at least one redundant update in the transaction log which is not in the incompressible sequence; and

    removing the redundant update from the transaction log.
