Hi guys, I have a question about the history query: https://stackoverflow.com/questions/67514972/datomic-hides-parts-of-its-history-when-query-is-about-all-attributes Maybe someone could help me?

It looks like you figured it out that the schema attributes had noHistory set to true. I also commented with a clarification about setting noHistory. While setting `:db/noHistory` should lessen the overall amount stored in history there are no guarantees about how much history is kept and some amount of history may be visible even for attributes with :db/noHistory set to true.

Thank you so much! I now realise that setting "noHistory" should be done much more carefully and maybe I didnt need noHistory at all....
