As an NGF user,
I want to configure percentage-based request mirroring,
So that my request mirroring does not have to be all or nothing.

GEP-3171 added an API for percentage-based request mirroring. With NGF supporting request mirroring as of 2.0, we can enhance this filter to allow to mirror a percentage of requests.

Acceptance

  • Users can configure percentage-based request-mirroring for HTTPRoutes and GRPCRoutes
  • Gateway API compatibility doc updated
  • conformance tests enabled

Dev notes

  • likely need to utilize split_clients to implement this
