Planning will be key.

Start a Workflow, e. g. a database query, after a certain time

The idea is to have a workflow that would iterate a number of times (v_number_of_intervals) with a set interval (of seconds) between (v_seconds_interval) them. The workflow looks for a trigger_file.csv if this file has changed from the last time the loop has run a component would be executed. If the file has not changed nothing would happen. Admittedly not the most elegant way but you could build a small automatic execu…

That being said I have created a sample workflow that would check the last date a file has been changed on a drive (here simulated using a local folder) - and if there has been a change compared to the last recored date a sub-workflow will be called and the new change date will be recorded in the CSV file. KNIME CSV writer has the option to append lines without writing the header. So it is suitable for recording such d…
