Looking good overall, my only comment isn't even a nit, just a flat remark.

[jesse-amano-hpe]

It's beginning to get a little confusing and disjointed, having all these extra table and column aliases off in their own functions just because some other function (filterRunQuery) might do something with rm.metadata. Not sure what we can do about it just now, but I think it's worth pointing out now and then so we keep thinking about it.

[AmanuelAaron]

We will be returning the metadata for groups in following PRs. For now we are just doing the default columns.
