Hi folks, I have started to use Storm recently but could not find any resources on the net about global grouping option's fault tolerance.
My question and understanding is as follows: While running a topology with a bolt(Bolt A) which is configured to use global grouping will receive outputs from the registered bolt's(Bolt B) tasks into just one task of Bolt A. As it is using global grouping option, there is only one task of Bolt A in the topology. What will happen if I am storing some historical data of the stream within Bolt A and the worker process dies which contains the task of Bolt A meaning that the data stored in this bolt will be lost? Pardon me if I am missing or have misunderstood something. I would appreciate if you can direct me to any sources. Thanks, Furkan
