> > I would argue that UnionExec should NEVER modify its inputs but just be a plain, simple node that forwards its inputs w/o messing up sorting (or any other property). > > I agree with this sentiment -- we already have `RepartitionExec` that concatenates batches from different streams Does it mean that the `UnionExec` will return the inputs sequentially (i.e. concatenated) or will it potentially interleave the inputs, whilst maintaining the ordering? -- This is an automated message from the Apache Git Service.
