I think this feature (diff / compare data from two separate DBs) is currently not functional (checked the documentation and noticed it is also (no longer) present there).
Further details here: Liquibase Diff command Using difftypes=data is not working
Sure, glad I could help!
I’m pretty sure lots of people want/need this, to but probably the team has a lot on the queue
I had the same need a while ago and I was fortunate enough to have a RedGate Data compare tool something (licensed) and that was pretty cool (for SQL Server).
Should find other options out there until this is fixed on Liquibase functionality (btw, this, comparing data process is not as easy as it looks).
Thanks all. The idea was suggested in our last Community Roadmap MeetUp back in February 2022 and is on the list of features being considered. To keep track of it and/or to provide feedback/vote, please head over the Liquibase Ideal Portal, it has its own card. Many thanks!
