Dian Fu commented on FLINK-4641:
--------------------------------
I have the same thought. :)
I'm asking this question is because I found that to achieve the above results,
we need make some modifications to the NFA. As when one branch is matched, we
need to eliminate all the {{ComputationState}}s corresponding to other
branches. Just to confirm my thought is right before make the changes. :)
