@masayuki038 thanks for this fix. It looks like two of the tests aren't passing for it? Could you take a look and investigate why?

@guidopetri @konnectr Thanks for your review.
Sure. I missed something. I'll check it later. Please give me a little time. |

First of all thanks for the fix on this, I was having this problem recently : D
In here, to make this more efficient, can't we just get the first row, and then generate the columns array from that outside for this for loop?
In this case every cell in the table requires this comparison which is in-efficient and whether we check row1 or rowN the columns will be same.

@clearnote01 I understand your comment. I also think that if it is normal RDB data, I should do that.
I thought that MongoDB can have a different column for each row, so I implemented it like this. Does such a case not exist?

@masayuki038 You are right, I don't think it's a problem when projection is specifically configured via $project, but there could be other cases that would break it.
Maybe it's safer to keep it as it is, and have a note that this could be optimized in the future if someone can rule out the edge cases.
