Right now it's just a HTTP server and REST framework. It's a very first release and I don't have any DB drivers for it yet- they would need to be non-blocking as you mentioned.
I have plans to write dbslayer like "access DB over REST" service as a companion to Luaw so that it can use any and all databases that have JDBC drivers available without having to write non-blocking driver specially for each new database. This kind of arrangement where DB connection pooling is abstracted out of application server itself has other advantages related to auto-scaling in cloud and red/black or "flip" code pushes at the cost of slightly more complex deployment.
All depends on how much spare time I actually get :(
