Abstract
A replication system that includes an asynchronous replication mode and a synchronous replication mode replicates data associated with a plurality of transactions. The replication system includes one or more target nodes connected via communication media in a topology. Each target node includes a database and a plurality of appliers allocated thereto. Each transaction has one or more transaction steps or operations. A first set of transaction steps or operations are allocated to the plurality of appliers on an object-by-object basis when the replication system operates in asynchronous replication mode. A second set of transaction steps or operations are allocated to the plurality of appliers on a transaction-by-transaction basis when the replication system operates in synchronous replication mode. The replication system further includes one or more originating nodes, and the requests for the first and second sets of transaction steps or operations to execute on an originating node can be initiated during the same time period.
