Loop execution progress

[mldendulk]

It would be nice to have a loop execution progress indicator when a loop is being executed.
When I use Group Loop Start, the number of groups should be known (right?). In the Loop End node this is Iterations, if I am correct. Would be really nice to have an indicator saying how many of the intended iterations have been processed when executing, so I don’t have to zombie-gaze at the screen until it is suddenly finished. #WalkToTheCoffeeMachine

Hello @mldendulk,

you can check current and max iteration variables in Node Monitor:

Feature suggestion: Loop end nodes

Hi, It will be useful to see the progress of the loop. In the Loop end nodes is only visible the string “queued”. Now, for checking the loop progress I look at the Loop Start nodes where are the numbers of the maximum number of iterations and the current iteration count as flow variables. Is possible to upgrade the various Loop end nodes and change the string “queued” with “currentIteration/maxIterations” or somehow show this two variables in the “Node Monitor” sheet. Regards Andrej

But proper loop progress indicator for sure would be useful:

Feature request: Proper progress updates for loop nodes

Is there any chance of getting a proper progress bar when using the loop nodes (especially the "Chunk Loop Start")? I'm currently checking the flow variables during long executions, but having the current progress within the workflow below the node would make things much more convenient. Regards, Philipp

Good evening,

while writing on a blog post I happen to have found this feature request. You might want to leverage the example workflow I created to track loop execution in detail.

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…

PS: There is also another similar feature request. You might draw some ideas from that and my example so we can consolidate all and draw attention of the developers to this request
