So, you got those quotes from the following page it seems (please cite your
source next time):
https://storm.apache.org/releases/current/FAQ.html
> *Number of workers a multiple of number of machines *
I'm not sure why that statement is there. It entirely depends on how many
topologies you are running, what they are doing, etc.
> *Number of kafka partitions a multiple of number of spout parallelism*
This is a bit confusing, but the point is that a given kafka partition can
only be handled by a single spout executor. You cannot have 2 spouts
reading from the same partition. So if you have say 10 kafka partitions
for a given topic, then the number of spout executors (i.e., the
parallelism) should be 1, 2, 5, or 10. Numbers that are a factor of 10.
Otherwise you'll have unused executors.
