@CzyerChen @weixiang1862 @yswdqz Any of you has interest in implementing this?
I am new to this repo - would like to pick this up. Can you add some more verbose details of what is required as part of the feature?

This is not easy. Do you read most of SkyWalking codebases?
I would say, you could consider to implement this. But don't be in urgent.
This requires you to have good understanding of the whole system.
I would like to take a shot at this. I will go through the docs and readme. Is there anything else you suggest me to do? Or a similar MR for a different Query language?
You could do as following
- Get familiar with project, and how to run showcase. https://skywalking.apache.org/docs/skywalking-showcase/next/readme/
- Learn MQE about the protocol and native UI for relative metrics.
- Learn PromQL service, and workflow.
- Try to implement this.
@wu-sheng I only have 16 GB RAM in my mac, I am not able to run showcase:
Release "demo" does not exist. Installing it now.
It's stuck on this step with RAM Utilization spiking up.
Is there another alternative?
You need to run necessary components only. Don't run the default. It includes all features.
