Abstract
Streaming database replication is provided by merging a stream of user transactions with a stream of copy transactions comprising copy data into a combined stream on a source. A target receives a single stream that includes copy transaction and concurrent user transactions in an order that enables conflicts between data being copied and user transactions to be handled correctly. Furthermore, locks applied to data subject to a copy transaction or user transaction can be released once the copy transaction or user transaction is added to the combined stream.
