Is there any plans to add sqlite/mysql/etc support?

Currently I don't have such plans, I think it's better to focus on new features and stability. Simple key-value storage is enough. BoldDB is used as local storage and S3 for distributed setup.

But if you want to add extra storage you are welcome (one requirement is a not large driver driver in order not to blow up dependencies).
