Hmm. It's essentially a hierarchical key/value store. You pass in queries (which is what mda-client.scm in the same repo helps with) and mda-server.scm executes them and sends back the response. So sending the message (via zmq) (put "value" "user" "key"), stores "value" in tokyocabinet with the key "user/key". (get "user" "key") returns "value" (via (tc-hdb-get db "user/key")). It also has a few misc functions for things like creating list/indexes and returning them, but those end up being just put/get eventually. I can't figure out how to isolate a test case yet. This is happening on my live webapp and I have only been able to reproduce it with a customer's data, which is not something I can share. I'm still working out how to get a generic test case.
