Hi Erik,
I have a question about primary keys. As far as I can see you're
currently using the first field of the relation as a primary key.
While that's what other databases do (and it is working well), I think
it would be better to make _records_ themselves primary keys. Since
records are immutab

Unfortunately not for all operations. For example, clojure.set/join
uses its own index function, which builds an

Clojure is not a great choice for this. It's oriented as a programming
language, not a database. It doesn't have any built-in persistence
mechanisms, and while it has many virtues, it's a little bit of a
memory hog. That isn't really what you want in an in-memory DB.
For anything more than a toy a
I'd love to see a persistent "table" type together with some common
primitives (select, join, union) and optimization capabilities.
Currently a "set of maps" does something like that but I have no idea
how to, for example, add an "index" to some particular field and use
it in other operations.

I have not found the system to be incredibly well documented, but I have
discovered that if you want to embed fleetdb in your app, you will need

Folks,
i would like advice,
cause since im starting something that will be eventually big data
intensive, from scratch
and i really like the options already built in in clojure like STM,
parallelizing data and concurrency logic implemented on it
i think its wonderfully tuned to use as database...
