There is no formal specification, but you can learn everything from
ngx_drizzle / ngx_postgres sources.
Take a look at those 3 files:

Because JSON parsers for Lua were already available ;)
Anyway, I believe that agentzh was/is working on RDS parser for Lua.

Not sure if this is helpful, but you can return binary data from PostgreSQL
(you should be using PostgreSQL instead of MySQL anyway :P) using
ngx_postgres with "postgres_output" directive. There is a reason why there
is no "drizzle_output" directive, but I'll let agentzh comment on that.
