HI,

What are the possible scenarios for the following!
Storm topology process at least once? even if any tuple fails who will replay 
tuple ? How trident process exactly once ? even if any tuple fail who will 
replay? need to write any code by developer.

While running storm application in cluster mode  i can able to execute my 
topology in required number of workers. but in trident topology always single 
worker is effected even i used setnumWorkers() method on config object.
Here My scenario  in need to read list of files fastly and process tuples 
exactly once  &  applying some conditions on tuple ,condition satisfied tuples 
need to write some where.
which topology is better trident or normal storm.   while when i go with 
trident ,trident state is mandatory ?even when designed application using 
ITridentSpout it emit batches but when i define parallelismHint to it ,it is 
not effected ?


Please help me ! no body cant giving any response !

 I hope You will give your valuable response!


Thanks & Regard's
