started some documentation on

Thanks Hao, Ralph etc. for offline review and suggestions, I would improve

In terms of the question ┬│if user adds a new metric to monitor, how
processing layer would change accordingly┬▓

I think if user adds a new metric, this metric should be added into
metadata table, and data source layer and processing layer should see
consistent list of metrics.

But we still need bake this design, please comment whatever is your
