@sdegutis: I usually have a leiningen alias lein create-db which runs the script to create the database. Documented in the README.md for development setup

and recently we've been using https://github.com/rkneufeld/conformity for "schema migrations"

I'm making an online game - but it is essentially single player. Reading up on Datomic's partitions, it seems to me that I should create a partition for each player, since they each have a lot of data, and I almost always want to query for facts about one player at a time. Am I understanding it correctly? Any thoughts?

We're looking at maybe 30-40k partitions in that case. How would datomic feel about that?

my understanding of partitions is to create a :users partition if you're going to retrieve a lot of users at once
