[18:20:44] <zigggggy> hi all.. I am using an API to get data, converting it into json and then persisting it to mongo.. before I save the document to mongo, I have to see if this document already exists and I just need to update some fields

[18:21:30] <zigggggy> so where I am stuck is this document object has a field like document.DocumentArray.DocumentArray and in this deeply nested array I want to update changed documents or insert if they are new
