@Yicong-Huang and I had an offline discussion. Here's a summary: - There can be two types of Union operators, one with "multi-link single port" (in the current codebase) and one with "two input ports" (not in the codebase) Let's call the second one "binary union." - Binary union is in the same family of other binary set operators such as "intersect" and "difference." - The semantic meaning of union is very unique, and it's already supported by the "multi-link single port" feature of each operator. To avoid confusion, I agree that we don't need a binary union. To summarize, the suggested plan will be to generalize the current "multi-link single port" union to all operators to allow multiple links to connect to a single input port. Optionally, we can keep or remove the current "multi-link single port" union. I suggest we remove it. @Yicong-Huang : please confirm if this summary is accurate. -- This is an automated message from the Apache Git Service.
