I recently learned about the Rails "bullet" gem that addresses the N+1 problem and determines when your app should or should not use eager fetching. Apparently it checks at runtime on the occurrence of N+1 loads that are not needed or the need for eager fetching to speed things up in instances where lazy fetching is being used.

Is there an equivalent plugin for Grails?

The short answer is, no. There isn't a plugin for Grails, at this time, that does this. You will need to manage the fetch mode manually through your code.

I recommend you develop your application first, then profile it to identify where a change to any fetch modes would be appropriate.

Remember the rule of "measure twice, cut once.".
