Nice, this reminds me a bit of the recent Lua integration in redis.
Transactor can be bottleneck and serves a relatively simple task. So I guessed it would be rewritten in other fast language such as C/C++ rather than Clojure as the project mature. But now the database functions and JVM are tightly-coupled. What do you think?
1) I'd assume that the bottleneck is IO, not CPU. But I could be wrong.
2) The JVM is pretty fast, especially for threading and the server workloads.
3) Clojure is not-so-slowly making its way on to several other platforms.
