go-demo-proxy

Proxies go-demo, so we can have distributed traces

TODO

  • call go-demo from go-demo-proxy
  • have query parameters
  • implement the same random error and delay as go-demo
    • with both, filter on query paremeter to enable/disable
    • this way, we can "discover" that specific flows are broken
  • add distributed tracing
    • include the query parameters in the span
    • include the error in the span
    • include the user agent in the span
  • add metrics
  • events?
