GitHub user dave-csc edited a comment on the discussion: Hop workflow issue: Process receives old rows instead of empty result after lookup
Hi @fcwojtul, I signaled this as a bug (check #4559 and #4581), but it's probably Hop's normal behaviour. A strategy to mitigate it, if you don't have to execute the next pipeline when you have no rows, would be modifying the previous one like this: - split the stream with a **Dummy** transform, before the final Copy rows to result - link a **Detect empty stream** to the Dummy transform, and then an **Abort** transform (I would also add a **Block until transform finish** between the two to catch the transit from _[EDIT!] other "dead ends" in the pipeline_, in case you have some long operations pending) In the parent workflow, you can catch the error stream and redirect that to other actions or pipelines. Hope this helps :) GitHub link: https://github.com/apache/hop/discussions/6059#discussioncomment-15037289 ---- This is an automatically sent email for [email protected].
