Thank you for the explanation. I have a follow up question. Does the entire request message, including HTTP headers, parameters, and body get sent to the Control Plane and forwarded to the node selected for execution? Or is data like parameters and body not sent to the Control Plane, but is sent directly from the initial landing node (GP-Node1) to the selected node (GP-Node2) over the HTTPS connection established in step 5? Putting it another way is the HTTPS connetion between GPNode-1 and GP-Node2 only used to send the response back from GP-Node2 to GP-Node1 or is it used for anything else?
Most of the headers and parameters will get sent to the control plane, but a request body is not. Basically anything that can be converted into a pipeline parameter could be passed up as part of the request, but any data that is passed into an input view (binary or document) will be transferred between CC nodes themselves. There are some additional optimizations that have been made to try and avoid the control plane portion of this flow as well, so sometimes it’s even possible to avoid those steps as well and everything is handled locally between plex nodes.
So in worst case, the headers and parameters may be passed up to control plane, but the body is passed between nodes.
