It appears that Datahike [0] is a Datomic workalike that supports branching. I haven’t tried it out myself (yet), but the documentation suggests it’s possible [1]. That said, I’m adding xitdb to the list of tech to try out. Thank you for building it! Oh, and thanks for linking to my article :-) [0]: https://github.com/replikativ/datahike [1]: https://datahike.io/notes/the-git-model-for-databases/
