| Description |
|
There's more than one part to this. I would start with these questions: 1) Given a Document (used in aggregation), how can we efficiently modify an individual array element at any path? 2) How can we integrate this with the existing execution machinery for $addFields and $project? Can this be modeled as an expression? |
