Your SQL is going to be "stored" one way or another, whether it's implicitly in the internal workings of an ORM, explicitly in code or mybatis style config, or explicitly in the DB. I think isolating it into data workers, and making them feed off a high throughput message queue (hiding restarts), minimizes the amount of redeploying needed.
