meteor Mongo Schema Migrations Blob Record From One Collection Into Another Collection (ie. Remove Join & Flatten)
Example
db.posts.find().forEach(function(doc){
if(doc.commentsBlobId){
var commentsBlob = db.comments.findOne({'_id': commentsBlobId });
db.posts.update({_id: doc._id}, {$set:{'comments': commentsBlob }}, false, true);
}
});
