How to get data from one Signal K server to another

[Shelis1976]

I have two servers in different localisation and for question purpouses i called them server1 and server two.
Serwer1 has all data colected. I want to transmit data from serwer1 to server2. It is important that server1 should be sender. Best if I can choose wchich data can be transmited and ex ones per 15 min.
Connection from server2 as a c;lient and server1 as a server works but it is not correct for me. Has anyone adwice how to built connections?

Mayby synchronization both servers is possible?
Thanks

I wrote signalk-to-batch-format and signalk-from-batch-format for this use case, although if you need a literal direct TCP connection, that's not how this works. There are lots of ways to achieve this, but this approach works for me. See the README https://github.com/c33howard/signalk-to-batch-format https://github.com/c33howard/signalk-from-batch-format

If you configure a connection like this in your server2

then server1 will send updated values to server2 every 10 seconds. If you want to pick individual paths that you want server 1 to send and specify different intervals for different paths you can use a subscription like

{
  "context": "*",
  "subscribe": [
    {
      "period": 10000,
      "path": "navigation.speedOverGround"
    },
    {
      "period": 20000,
      "path": "environment.depth.belowTransducer"
    }
  ]
}

Why are you saying that this kind of a setup "is not correct for you" ?
