Hi, I was doing comparison of Open Stack Swift response headers and Ceph RGW response. This is in regard to X-Trans-Id header in response from Open Stack Swift storage. Swift response to a request always have the header "X-Trans-Id". X-Trans-Id : A unique transaction identifier for this request. X-Trans-Id seems to serve two purpose: 1. Every log messages for a request will carry this and aid in debugging/analyzing. 2. Benchmarking for latency. So, do we have similar unique identifier in Ceph RGW response which associates with each request? Or do we need add support for this?
