Abstract: A system, a method, and a computer program product for replication of data changes are disclosed. Based on a received data query, at least one attribute of stored data is identified for replication. The attribute corresponds to at least one parameter of the received query. Data stored at a first time and data stored at a second time are retrieved. The second time is subsequent to the first time. Data stored at the first time is compared to the data stored at the second time to determine a delta difference between the data stored at the first and second times. The computed delta difference is selected for the identified attribute. The selected computed delta difference is replicated in response to the received query.
