I don't know about "normal", but expected would be as per the documentation. See Stream Groupings :
https://storm.apache.org/documentation/Concepts.html You will find the specifics of your situation in the definition of your topology. For Shuffle / all / none Grouping, what you described would be unexpected. For Local or Shuffle Grouping, what you described would be expected, but, only if the sending and receiving bolt are in the same executor. For Filed / partial key / global / direct - whether or not what you described would be expected depends upon your topology's application.

However when I look at the executors for each bolt, some are always at 40-50% capacity and others are always at 90-100% capacity. Is this normal? Is there any way to manually smoothen this?
