> If a PCollection serves as side-input to multiple ParDos, it would be evaluated, collected on the driver and finally broadcasted repeatedly for every such ParDo. @mosche does this mean the pcollections are re-computed? So if you do: ```py pcoll_1 = pipeline | "ParDo 1" >> ParDo(...) pcoll_2 = pipeline | "ParDo 2" >> ParDo(..., my_side_input=pcoll_1) pcoll_3 = pipeline | "ParDo 3" >> ParDo(..., my_side_input=pcoll_2) ``` Will `ParDo 1` be computed 3 times, and `ParDo 2` be computed 2 times? -- This is an automated message from the Apache Git Service.
