Subject Re: simple question about grouping

Grouping makes sense only when you have more than one task for a bolt. If your bolt has more
than one task, then the grouping will decide how the tuples from the spout are distributed
to the individual tasks of the bolt. (shuffe = random, fields = keyed on some field and so
on). 

 

See http://storm.apache.org/releases/current/Concepts.html 

 

Thanks,

Arun

Subject: simple question about grouping

 

i have text file contains data . size of this file is 3.5 MB . My topology consists of one
spout and one bolt so is that possible to make all processing in one bolt and in this case
what is the role of grouping here ? 

Thanks in advance
