@knime Is there an issue with columnar backend and loops.
Chunk loop ends etc… take absolutely forever to process destroying any processing uplift from using the format.
Hi @Gavin_Attard -
Seems like this is a follow-on to your previous thread discussed here, is that right?
Let me ping one of our devs internally to see if they have any insight to offer.
Hi again @Gavin_Attard -
I heard back from the devs. There has already been a fix implemented for use of columnar backend for “common” loop ends (for example the standard Loop End).
The Parallel Chunk End has not been adapted yet, and they are aware of the performance issues. Fortunately there is a ticket for it (AP-19971) that is being worked on.
Hope that helps clarify for you!
smashing @ScottF , Thank you so much.
fingers crossed on the fix some time soon
