Abstract:
During replication of transaction data from a source database to a target database via a change queue associated with the source database, one or more multiple paths are provided between the change queue and the target database. The one or more multiple paths cause at least some of the transaction data to become unserialized. At least some of the unserialized data is reserialized prior to or upon applying the originally unserialized transaction data to the target database. If the current transaction load is close or equal to the maximum transaction load capacity of a path between the change queue and the target database, another path is provided. If the maximum transaction threshold limit of an applier associated with the target database has been reached, open transactions may be prematurely committed.
