> +Question:+
> How to create different record for every update in FIWARE-Draco?
> +Description:+
> I just started using FIWARE and I'm having trouble with the data I want to persist on MongoDB using Draco. I am using a Python script that creates my context data with a specific id (by a POST request to Orion)  and then updates certain attributes of this data (by a PATCH request to update multiple attributes) by using FIWARE Orion Context Broker.
> While I can't see any problem when I observe the JSON data from this script, HTTP requests and Apache NiFi flow, MongoDB keeps only the last updated version of this data in the related collection. Because of this, I cannot perform time series functions. However I can see the "creDate" and "modDate" metadatas in attributes. But I need different records for every update to receive them.
> Here is te subscription request body from Postman Client. fiware-service and fiware-servicepath headers are also included in my requests:
> {
>   "description": "Notify Draco of all context changes",
>   "subject": {
>     "entities": [
>       {
>         "idPattern": ".*"
>       }
>     ]
>   },
>   "notification": {
>     "http": {
>       "url": "http://hostIP:5050/v2/notify"
>     }
>   },
>   "throttling": 5
> }
> Here is what I get in MongoDB collection, attrNames has been made dummy for the question:
> {
>   "_id": {

>     "type": "Log",

> I've gone through all the docs but either couldn't find the solution or am I missing something in the architectural logic. How should I go about the issue?
> Thanks!
