Is there a good practice around queries that return a lot of data? Querries that one would use pagination in a sql db

@wistb Datomic has no built-in support for transactions that span multiple databases.

Is possible to do recursive queries? category(root) has :category/subcategory or :category/items :category/subcategory can be another :category/subcategory or :category/items

@souenzzo look at the rules examples in the mbrainz sample repo. they do stuff like this i think

I tryied some mutual recursion/simple recursion on rules, but no erros and no result... 😞

I'm curious if anyone's ever tried using datomic for coordination (e.g. as a ZooKeeper replacement)

On the surface it seems like basically all the semantics you need are there (minus callbacks, which you could replicate with polling or the tx queue).

The only thing that's obviously missing is ephemeral nodes. But I'm pretty sure you could ape that with a heartbeat as well.
