Continue Async Task after return statement too.

[bimalta...@gmail.com]

 I have a Rest API, where I have called an aws service and save the records on a single endpoint at the same time. In order to respond quickly, I want to run the aws service asynchronously, even after the API responds too in grails. Please suggest how could I achieve it?

I have included a prototype of the  async task implemented in a service  as :

def method1(){

        task {

       // time consuming service call.

        Thread.sleep(50000)

   }.onError{ Throwable error ->

         println ":::::: Error :::::"+error.getMessage()

  }

 saverecords();

return ["msg":"success"]

}

I want to return the success message on the complete execution of saverecords() function and continue the task (process) in the background. But i have got an error on the completion of task thread execution.
