Does KNIME intelligently recognize and process only new information in a CSV file within a workflow, or does it process all rows regardless of their modification status? I’m looking for insights on how KNIME handles incremental loading and processing of data in a CSV file, specifically in scenarios where there is no timestamp column available for tracking modifications. Any suggestions or best practices for achieving efficient processing of only new or modified data in KNIME would be greatly appreciated!
