Just for the record there's a ToDo in the GraphBasedDbRowOpSorter explaining a
bit what was improved.
> Tweak GraphBasedDbRowOpSorter logic to allow related updates

> Key: CAY-2867
> URL: https://issues.apache.org/jira/browse/CAY-2867
> Project: Cayenne
> Issue Type: Improvement
> Components: Core Library
> Reporter: Nikita Timofeev
> Assignee: Nikita Timofeev
> Priority: Major
> Fix For: 4.2.2, 5.0-M1
>
>
> Current version of the {{GraphBasedDbRowOpSorter}} consider updates as an
> edge at the graph building stage. However this seems like a faulty assumption
> (at least in some cases).
> So we need to research this and try to remove unnecessary graph edges.
> This in turn will allow more flush operations to pass successfully compared
> to the {{DefaultDbRowOpSorter}}
