That is true, but isn’t it trivially solvable with the datomic model? You just have a datum “significant event” list and add stuff to it?

You still get all the benefits of event sourcing, but then you can query the state much more easily.

At least that’s what it looks to me from a cursory look at datomic and daily struggles with normal event sourcing (kafka)



Have you written about your daily struggles somewhere? I, for one, would be very interested reading about it as I think not nearly enough people talk about the cons/war stories when it comes to ES (or I just don't find those blogs).


We didn’t have much success with it, but there are tools like Debezium that read the Postgres WAL and send row level changes like this to Kafka
