How to force flushing in Grails GORM

I have a service that distributes tasks to operators. Inside a method I distribute many tasks in time inside a loop. I want to flush the task, the operator, and a DistributionLog. If I just had one domain to save I think I could do something like

Operator.withTransaction{ //...some code }

but I have at least 3 domains to save and to make it even worse, two of them have dependency on each other. The operator have a list of tasks.

I can't wait all the distribution to finish before an operator can get his tasks, so I have to force it to flush. To make it even harder, it's all inside a multitenantService.doWithTenant() (multitenant plugin)

You can get the session using the withSession method available in all domain classes and call to flush() on it.

Operator.withSession { session ->
   // ...
   session.flush()
}

If you want to do an explicit flush, you can get a reference to the hibernate session factory in your grails service like this:

def sessionFactory

You can then get the current hibernate session, and call flush on that:

sessionFactory.currentSession.flush()

See the documentation:

http://grails.github.io/grails-doc/2.2.5/ref/Domain%20Classes/save.html

The save method informs the persistence context that an instance should be saved or updated. The object will not be persisted immediately unless the flush argument is used:

b.save(flush: true)

You can force a flush with flush argument to the last call to save:

obj.save flush:true
