jerrypeng commented on issue #3055: Add custom operator support URL: https://github.com/apache/incubator-heron/pull/3055#issuecomment-437713929 @nwangtw can you please provide an example topology that uses the custom operator? Also, isn't the point of the custom operator to provide some sort of compatibility with the "Storm" API? Instead of forcing users to copy their code to the corresponding "prepare" and "execute" methods in the custom operator, couldn't we just do something like CustomOperator(Bolt)? So that the user that just use their existing spout or bolt implementation? and the CustomOperator is just a wrapper for bolts which allows them to be used in streamlet topologies.
