Hi,

Is there an existing way to get the update history and save it in a history database.
For example: There is an order document, which gets edited by multiple entities and for now I am doing a manual save in the history collection whenever the order document is edited. 
1. I was wondering is there a better way to do this?
2. Is there a way to just store the diff?

TIA.

Hi, you can look at change streams in mongodb and this blog may help.

Also you can watch updates on a collection with pymongo db.collection_name.watch()  function.

Thanks,
