I think we are digressing from the plan we had put forward if we have to go down this path. We should understand what it means by going down the YAML format. Also, what would happen if there is another innovation in 3 months?

We already have scatter-gather test suite ported to DPDK repo and has undergone review in the community.

In the last meeting we went through a simple test case. Is it possible to write the scatter-gather test case in YAML and see how they compare?
