Description Christoph Jerolimov 2022-06-21 12:30:41 UTC 
Description of problem:
As a user, I want to have a performant topology graph. There is a rendering loop when displaying a Http EventSink (KameletBinding).

At the moment, it doesn't break the performance, but we might find the root cause of this rerender loop!

Version-Release number of selected component (if applicable):
4.11

How reproducible:
Always

Steps to Reproduce:
1. Install Serverless and Camel K operator
2. Create required eventing resources
3. Open the developer perspective
4. Navigate to Add > Event Sinks and search for HTTP
5. Select "HTTP Sink" and press on "Create Event Sink"
6. Enter any URL and press Create
7. Navigate to the topology graph, open the react dev tools (browser extension)
8. Select the React Components tab and enable "Highlight updates when component render."

Locally you can also add a console.log into EventSink in packages/knative-plugin/src/topology/components/nodes/EventSink.tsx

Actual results:
The component is rendered hundred of times.

Expected results:
The component should not be rerendered so often...
