I have a pipeline that takes chunks from a database and does some chemical calculations on them.
I have to chunk the data, it is to large to process it in one go, it crashes knime.
For efficiency reasons i prefilter the data, wich leads to empty chunks.
What i would like is to skip the calculation part (wich is taking up quite some processing time even on empty chunks) if the chunk is empty.
But putting an Empty table switch and a Concatenate node in the loop gives the following error:
ERROR Variable Loop End Loop End node in inactive branch not allowed.
Is there a way around this ?
