Question on Vivaldi Coordinates in Serf

[haarsh85]

Hello,

I am reaching out to clarify one issue that I am facing related to Vivaldi coordinates in serf. I kindly seek your guidance if possible.

I have a few nodes running serf and now I need to get the coordinates of these nodes. So far, I have used a custom code to get the coordinates via RPC command get-coordinate and was able to get coordinates of the particular node where I am running the code. For example, if I run the code to get coordinates on node A it only gives the coordinate for node A, but not for other nodes. It only gives the coordinates for single node.

Example output:

"Coord": {
        "Adjustment": 0.005490151789333412,
        "Error": 0.219644087147879,
        "Height": 0.0010579494498964698,
        "Vec": [
            -0.007289323104222218,
            -0.002864383432168282
        ]
    },
    "Ok": true

The problem is I want to have a search algorithm (range query) on any selected node to get all nodes within a certain latency. For example, I want to have a way to get all nodes that are within 10ms from Node A, which needs to give me all the respective nodes. As I think to do this I need to have all the coordinates of other nodes (like a table) in Node A so that I can use this table to get the applicable nodes.

Would it be possible to handle this?

Thank you so much for kind assistance.
