 #### Using PATCH save method
 - There are two save methods of triggering data update, PUT and PATCH defined in the payload using the `save_method` field
 - Using PUT basically places(overrides if path exists) data at the specified `dst_path`

 - Let's say a user is deleted from the system and we would want that user details to be removed from the JSON, let's remove bob from the list, we can use the `remove` operation of JSON patch to achieve this

+:::note
+The primariy way meant to do updates with OPAL is with the `PUT` method; `PATCH` is better used for light tweaks to the data.
+While future versions of OPAL might have deeper support for PATCH, it is not currently the case.
+To build complex data layouts - we recommend building data-updates into keys that do not intersect to build larger data-sets, and when they do intersect we’d recommend updating the entire entry.
+If you want to use PATCH and have more control over its behavior you can implement a custom data fetcher that will handle the order of writing or dependencies.

 ### Option 3: Write your own - import code from the OPAL's packages
 - One of the great things about OPAL being written in Python is that you can easily reuse its code.
 See the code for the `DataUpdate` model at [opal_common/schemas/data.py](https://github.com/permitio/opal/blob/master/packages/opal-common/opal_common/schemas/data.py) and use it within your own code to send an update to the server
