my wrapper throttles the emit speed of the spout that is wrapped.
Feel free to use it. Feedback is welcome.

Hello all,
Is there any way to pass the folder to storm submit command so that all
the contents of it can be shared on all the supervisor nodes .
Can we use lib folder ? As I guess all the jars are transferred from nimbus

Not like that.. But i have used workers equal to number of cores. Each vm

Since every worker process have only one thread for transfer of message
from network to executor queue so more often it becomes a bottkeneck when
input rate is high.. That forces us to have more than 1 worker on same
node.
I dont think other than this there is any logic dependent topo case
