This is the first time I try reading a Jepsen report in-depth, but I really like the clear description of Datomic's intra-transaction behavior. I didn't realize how little I understood the difference between Datomic's transactions and those of SQL databases.

One thing that stands out to me is this paragraph

  Datomic used to refer to the data structure passed to d/transact as a “transaction”, and to its elements as “statements” or “operations”. Going forward, Datomic intends to refer to this structure as a “transaction request”, and to its elements as “data”.

What does this mean for d/transact-async and related functionality from the datomic.api namespace? I haven't used Datomic in nearly a year. A lot seems to have changed.
