Module proxy_mirror 

Request-mirroring plugin (proxy-mirror).

The featherbit port of Apache APISIX’s proxy-mirror: fires a fire-and- forget clone of the incoming request at a shadow upstream for traffic shadowing (comparing a new backend, capturing traffic, …). The mirror is sent on a detached background task via the shared outbound client; its response and any error are ignored, and the request path is never blocked or affected by it.

Placement: put this node before upstream so it observes the request as it will be proxied. It always continues through the success port and never errors.
