Visual Debugging

[XiaoKuge]

When we have more nodes (for example: 10, or even 100) involved in the flow . It is very difficult to debug the system.

The most desired feature is to understand what the node's input, output in a easy-to-eyes, easy-to-click way.

Here is the specific need decribed by our (dora application) developers.
"We need

• a visual interface which represent the running process of a dataflow.
• The interface should include all the (or selected) nodes in the dataflow.
• Use colors. For example: during the running of the dataflow, when a node receives data and starts running, its color should change. If an error occurs in a node, the color of the node with the error should be marked, and the error message should be prominently displayed. (Additionally, the associated input should also be shown.)
• Also, the value of input and output parameters of the currently running node, including the execution time, should be visible on the page.
  "
  of course, debug functions could also include:
• breakpoint setting
• step execution
• run and resume
  and many other functionalities, but those are not the immediate need.

I don't think we have the bandwidth for this at the moment sorry.

I think @phil-opp is working on a running data visualization but it would not be as feature rich as you're describing
