While preparing my presentation for POUG 2018 conference I have found some different behavior in Parallel Intgrated Replicat. This is a new Replicat type available from version 12.3. According to Oracle internal tests Parallel Replicat can be up to 5 times faster than Integrated Replicat in the same test case. I have done a number of tests with various options but one thing struck me. Every time the Replicat rearranges the order of DML operations. And there is no way to turn it off.
