Hello I am thinking of using stateful bolts to manage state of a bolt. From the documentation it is not clear how to save the bolt state however. I understand it has to be done when we process the checkpoint tuple, but how? Do I just need to update the state object and storm pick it up during three phase commit? How does Strom know which state object to pick for check pointing?
I wasn't able to fine more complete examples either, specifically when we can't keep the state in a kev/value map. Also, Is this functionality tested in production like environments before? Thanks M
