11.2.2 RxGORM
RxGORM is new implementation of GORM that has the following goals:
- 
Reactive 
- 
Non-blocking 
- 
Stateless 
- 
Simple 
RxGORM, unlike the Asynchronous GORM implementation, aims to be truly non-blocking, down to the driver level.
The following is an example of RxGORM in action:
You can combine RxGORM with the RxJava plugin to implement reactive responses from Grails controllers. For example:
def show() {
        // returns an rx.Observable
    Book.get(params.id?.toString())
}For more information on how to use RxGORM, see the RxGORM user guide.
