• Performance: Increase index-parallelism limit from 8 to 128.
i bet there is a cool story to why this became necessary!
> What do you think the chances are of a Clojure runtime bump with the Cloud Release? Just give it to me straight! What are my chances?

Are re-transacting the same set of :db/add and :db/retract sets then deterministic? So that you could replicate or restore a Datomic db from an existing transaction log. If I remember my experiments correctly this was the only blocker: > Fix: Transactions no longer consume entity ids for tempids that resolve to existing entities through upsert.
