An embodiment operates by assigning a first unique identifier to a first log entry associated with a disk store, a second unique identifier to a second log entry associated with in an in memory row store, and a third unique identifier to a third log entry based on the second unique identifier. The embodiment further operates by determining a first stream package based on the first log entry, a second stream package based on the third log entry, and a replay order for the first stream package and the second stream package based on the unique identifiers. In some embodiments, the operation further includes sending the first stream package and the second stream package to a replicant server in accordance with the replay order.
