This sort of thing is also the goal of Datacrypt & Hitchhiker trees
(https://github.com/datacrypt-project/hitchhiker-tree), which are designed
to be highly optimized for I/O.
We've been making progress on the GC and adding new backends--it would be
awesome to be able add a CLJS port too :)
Actually, in Datomic, the namespaces don't have any special meaning for the
database itself--you can choose to use whatever namespace (or even no
namespace)! Using namespaces is a convention to help you keep track of
which attributes belong to which entities.
We don't use a separate model
These are very useful! Thanks!

Could you compare lein-modules with lein-voom? I can see that they have

appropriate.
This looks like a great tool for large projects. Thank you!
