Issue
In earlier releases of Redpanda Connect , when using redpanda_migrator there was a potential for issues where ordering might not be as expected on the destination topic(s).
Resolution
There was a bug in releases lower than Redpanda Connect 4.69.0 which could impact ordering.
As long as Redpanda Connect is on release 4.69.0 or higher, ordering is maintained on the destination topic(s).
Note that for the outputs, max_in_flight does not need to be set to 1 to maintain ordering , it can be set at default values or higher values depending on numbers of partitions.
