I couldn't follow his arguments against event sourcing. Could someone elaborate on the differences?

- dominotw 9y agoApparently dataomic creates indexes for you[1] so you don't have to write views on top of the events like you'd do if you use just insert events in a table in postgres. So for example if you want to count the number of page views for a particular user, you'd simply use EAVT Index for that particular userId. https://docs.datomic.com/cloud/query/raw-index-access.html https://docs.datomic.com/cloud/query/raw-index-access.html
- augustl 9y agoYup. You don't create your own views, you get a generic query engine and generic indices instead. On top of all the other benefits, like cheap as-of time travel.
