Show loop progress in data app

[andyoeyen]

Is there a way to show the progress of a loop in the data app? I have an app that will iterate over 15 items and i want to show when an iteration is finished.
I can put a component inside the loop, but this results in a data app where the user has to click next every time an iteration is finished.
If I put the loop in the component, the entire loop has to be finished before something is shown. My app goes from 0%→ 80% and stays 80% for 10 minutes without the user knowing wat the app is doing. It would be nice to have a component that is updated during the loop or a component that will go automatically to the next step, without the user clicking on the next button, when finished.

Or maybe there’s anonther option i didn’t find?

@andyoeyen welcome to the KNIME Forum. There is a solution by @mwiegand you can find here:

Monitor Loop Progression in the Knime Console - Example Workflow

Hi KNIME community! I wanted to share a helpful method, including an example workflow, for tracking loop progress in KNIME, which is especially useful in long-running workflows or when using Parallel Chunk Loop Nodes. This approach uses a Java Snippet node to create a console-based progress bar that updates on each loop iteration. With this progress indicator, you can: Monitor loop progress in real-time. Debug potential bottlenecks. Gain insight into resource distribution in parallel executi…

In addition there is a discussion about the use of node annotations:

Feature Request around Loops

Nice components @HansS. I’d made a component using Node Annotator for similar reasons, but with just the basic iteration counter. I particularly like your ideas for including percentage and group information.

The component with annotation idea got extended further here

Visual Progress Bar for loops

Having a bit of “KNIME fun” as its the weekend, but hey it may be useful There have been a few mentions on the forum regarding loop progress indication, such as here: This inspired me to see if something a little more “visual” could be achieved. I have used Node Annotator from the the Nodepit Power Nodes for this this so you need that extension installed if you want to try this out. Ah… but we can only annotate nodes with TEXT, right ? Well yes… that is true… but undeterred… …

Hi,
Thx for the reply, but I already read those topics. They are not a solution for my problem.
I want data app users on the business hub to view this progress. They don’t have access to a console or the workflow. They can only see the ‘wizard’ like datapp.

kind regards,

Andy
