Hi guys. I'm new on apache Beam and o would like some help to undestand some behaviours.
1. Is there some performance issue when i'm reading data from a relational database using a ParDo instead of BoundedSource? 2. If I'm going to implement a BoundedSource how does Beam manage the connection? I need to open and close in every method, like split, read, estimete size and so on?? 3. I read something about splittable dofn but i didnt fine instructions about to How implement. Has anyone have something about ir? Thanks
