Hi,

i have a problem with the Parallel Chunk End Node. I created a workflow to read and write MS SQL Data tables from one into another Database with 1.000.000 + Rows each. The table names which will be processed come from a CSV. I want to use the parallel Chunk Nodes to parallelize those transactions. The parallel data transfer works but i always get errors from the parallel chunk end Node as the following at the end of the workflow.

Hello pascalW,

Welcome to the KNIME Forum!

Is it possible to share a workflow with a similar structure with some dummy data, so that we can check what is causing the error?

Best,
Keerthan
