> Hello,
> i am facing a problem and your help will be really appreciated.
> so, i am using storm 1.0.1, i prepared a topology that transfers data throw a
> preparation bolt then to a python prediction bolt.
> in prediction bolt i am collecting data in real time and creating group of
> data then sending them to prediction function.
> this topology works perfectly in one machine where the machine can process
> all the data, but not in distributed cluster as each machine work separately
> and some data needed for grouping can be processed by different machine.
> Is there a way that bolts communicate with each other and so we can group
> data even if they are on different machines?
> can you please advice and thank you
