I'm quite new to Storm. I have a simple question about whether to use Field or Shuffle grouping. Am I correcting to understand that the reason to use FieldGrouping is when you have some sort of state in your bolt so you want to have the tuple with the same field go to the same Bolt. If my Topology is simple as get some data parse some JSON and pass that JSON stream to DB. I don't really need to use Field grouping? And shuffle grouping would be better in this case?
Thanks.
