Add option to create a changelog/audit trail on a database

[VianneyMI]

I'd like to have a feature to see the history of a given document in my database let's say I first load the following document as-is:

#A
{
   "_id":1234
   "name":"John",
   "age':18,
   "hobbies":["Programming", "Video Games"],
}

that then changes to:

#B
{
   "_id":1234
   "name":"John",
   "age':19,
   "hobbies":["Programming", "Video Games", "Economics"]
}

I'd like that the update query that make the document moves from A to B also creates an event in a changelog collection where I would have something like:

{
    "_id":"event_n",
    "collection":"users",
    "update_one":
    "impacted_documents" : [{
        "_id":1234,
        "age":{
            "old":18,
            "new":19
       }
       "hobbies":{
           "old":["Programming", "Video Games"],
           "new":["Programming", "Video Games", "Economics"]
        }]
}
