Hi. You don't have to change the library in order to make it work through fibers. You have to wrap it. In case it has efficient implementation of the async-api you have to implement the fiber-synchronous using the asynchronous api. If it hasn't you have to wrap it with threadpool. You can take a look in the implementation of the JDBC wrapper here: https://github.com/puniverse/comsat/tree/master/comsat-jdbc
