Do service-splitters have "sticky sessions" (& how to disable them)?

Hello,
I’m testing retries in service-routers and it seems that if I chain a router and a splitter, the same split destination is always used in case of retry.

Here’s an example :

kind = "service-router"
name = "backend"

routes = [
  {
    match {
      http {
        path_prefix = "/v2"
      }
    }
    destination {
      service = "echo2"
    }
  },
  {
    match {
      http {
        path_prefix = "/"
      }
    }
    destination {
      service = "echo1"
      num_retries = 3
      retry_on_status_codes = [500]
    }
  },
]
kind = "service-splitter"
name = "echo1"

splits = [
  {
    weight  = 90
  },
  {
    weight  = 10
    service = "chaos"
  },
]

NB : the chaos service always returns a 500.

The observed behavior is each time the traffic resolves on chaos, the retries will all go there too. Is there a way to change that ?

I think I read somewhere that all the Consul resolution was done for a TCP connection, so the retries keep the same connection…

best,
Matthieu
