I don't know exactly how to do it in Datomic, but since it's append-only, it must be possible to do something like "state of DB at this point in time".

- valw 10y agoIt is (without any time restriction re: GC etc.) The exact term would be 'accumulate-only' (technically, 'append-only' is more of a storage implementation detail). Interestingly, you can also make 'WHAT IF' queries i.e obtained a view as if some writes were made (but without transacting them).
