Hi, many thanks for your answers. Can someone describe this test scenario with 60 masters? Is the topology available to have a look at? I think this will not be a fully meshed scenario (multi-master with meshed replication threads), right? It would be nice to have some insight into the "test" scenario: - How many replication agreements were created and how were the changelogs set up? - Are there measurement results for the utilization and data flow? Regards, Eugen
