Abstract
Systems and methods are provided for synchronizing operational data records in a manner that reduces redundant copying of data. A set of operational data records is stored, wherein each data record is assigned a unique ID in ascending order based on a creation time of the data record. A highest unique ID is identified from the operational data records in the set of operational data records. A tolerance number is identified that is indicative of a range of unique IDs that can be processed at a same time such that it cannot be guaranteed that operational data records with unique IDs separated by less than the tolerance number were assigned unique IDs in the order that the operational data records were created. A synchronization ID is calculated comprising subtracting the tolerance number from the highest unique ID. The synchronization ID is transmitted to the source operational data store.
