There is an integration between DataFusion and Delta Lake that provides some level of transaction support. I have no idea if it qualifies as MVCC or not (I have not spent time looking at this project in detail yet).
https://github.com/delta-io/delta-rs#features It would be good to know more about your requirements though. Are you looking to build an OLTP database on top of DataFusion for example? Hope that is helpful. Andy.
