Hi, I was trying to add the support to reuse existing Bolts in the Streamlet API last week and got some feedbacks about the feature and the improvements. After reconsidering what I want to have, I think it can be generalized a bit to "Custom Operator".
Here is a design doc to summerize what in my mind and what I am planning to do. Please feel free to comment: https://docs.google.com/document/d/1XzF0IlfuaaW8Gx3cPx1xLtP-kgCFK0TRNS5aAzuMuMg/edit#. All ideas are welcome. Thanks in advance!
