Hello! Does anyone using datomic analytics with presto + metabase have a working solution group by time based attributes? Pretty much an answer for this question https://forum.datomic.com/t/time-and-histories-in-analytics/1717

Hello! Does dev-local support transaction functions ? The documentation that I’ve managed to find is not clear if they are or not I’m trying to install a function via :db/fn , but it fails with ” Unable to resolve entity: :db/fn”..

I believe most of https://github.com/cognitect-labs/day-of-datomic-cloud works locally using dev-local but the exercises with tx fns require that you actually deploy to Ions so I guess the answer is no. But I might have got some things wrong...

i think u can use tx fns, but u don't have to transact them, just simply have them on the classpath. u might need to have a datomic/ion-config.edn with an :allow declaration to enable the use of your function in transactions: https://docs.datomic.com/cloud/ions/ions-reference.html#ion-config but not sure if that's necessary, when using dev-local.

@U0522TWDA No need to deploy ions to get transaction functions, you can use them with dev-local.
