Interesting, multiple mutations that is. Are we talking multiples on the same row id?
Upon reflection, I realized the embedded thing is nothing special. I think I'll keep adding columns to a single mutation. This will make for a wide row, but I'm not seeing that as a problem. I am I being naive? Another question if I may. As I walk my graph, I must keep track of the type of the value being persisted. I am using the qualifier for this, putting in it a URI that indicates the type. Is this a proper use for the qualifier?
