I'm with Erinn on this one. Lateral flatten() is the way to go. Though I gotta say, these options are a bit of a mixed bag, aren't they?

METADATA$ACTION()? What kind of made-up function is that? Definitely not the solution we need.

Transpose()? Nah, that's not what we're looking for here. Gotta be lateral flatten() all the way.

I'm not sure about METADATA$ACTION (), but I know that Transpose() is not the right function for this task.

Hold up, option A? Really? You can't apply transformations on stream data? That's just nonsense!

Hmm, I'd go with option B. Lateral flatten() seems like the perfect SQL function to transform that JSON data into relational columns.
