How to workflow that run whenever new text added to directory that change into CSV
with our commercial product,
KNIME Server, you can schedule workflows that can check for changes and if changes are detected execute other follow-up workflows.
With just the Analytics Platform, this is not directly possible.
@Deepaksd I also would recommend the KNIME server. You can look at this discussion tough. But be aware that these ar mearly workarounds and in no way meant for a stable production of sorts. You will also find links to KNIME server on AWS and Azure cloud so you can have easy access to its functions.
@USCHUKN1ME I tried to build a system you might be able to expand and use.
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…
You could absolutely combine the approaches, I would think.
@kienerj for pointing to this feature.
Another interesting function could be this component by @gab1one that would wait for a file to change. In order to bring this into a ‘looping system’ - some changes might be necessary. In my example I tried to do a small such system with generic KNIME nodes.
