DiffSync acts as an intermediate translation layer between all of the data sets you are diffing and/or syncing. In practical terms, this means that to use DiffSync, you will define a set of data models as well as the “adapters” needed to translate between each base data source and the data model. In Python terms, the adapters will be subclasses of the `Adapter` class, and each data model class will be a subclass of the `DiffSyncModel` class.
Once you have used each adapter to load each data source into a collection of data model records, you can then ask DiffSync to “diff” the two data sets, and it will produce a structured representation of the difference between them. In Python, this is accomplished by calling the `diff_to()` or `diff_from()` method on one adapter and passing the other adapter as a parameter.
You can also ask DiffSync to “sync” one data set onto the other, and it will instruct your adapter as to the steps it needs to take to make sure that its data set accurately reflects the other. In Python, this is accomplished by calling the `sync_to()` or `sync_from()` method on one adapter and passing the other adapter as a parameter.

By default, `Diffsync` supports a local memory storage. All the loaded models from the adapters will be stored in memory, and become available for the diff calculation and sync process. This default behavior works well when executing all the steps in the same process, having access to the same memory space. However, if you want to scale out the execution of the tasks, running it in different processes or in totally different workers, a more distributed memory support is necessary.

The `store` is a class attribute in the `Adapter` class, but all the store operations in that class are abstracted in the following methods: `get_all_model_names`, `get`, `get_by_uids`, `add`, `update`, `remove`, `get_or_instantiate`, `update_or_instantiate` and `count`.

If you prefer to update the entire remote system with the final state after performing all individual create/update/delete operations (as might be the case if your "remote system" is a single YAML or JSON file), the easiest place to implement this logic is in the `sync_complete()` callback method that is automatically invoked by DiffSync upon completion of a sync operation.

The main diffsync class `diffsync.Diffsync` has been renamed to `diffsync.Adapter` as we have found that this is the verbiage that is most often used by users and explains the intent of the class clearer. The old name will still be around until 2.1, but is considered deprecated at this point.

As a consequence, a lot of fields have been renamed all across diffsync. To the end user, this will most prominently appear in the signature of the `create` method, where you will have to rename the `diffsync` parameter to `adapter`.
The first time you run this example, a lot of changes should be reported between Nautobot and the local data because by default the demo instance doesn't have the subregion defined.

After the first sync, on subsequent runs, the diff should show no changes.

At this point, `Diffsync` will be able to identify and fix all changes in Nautobot. You can try to add/update or delete any country in Nautobot and DiffSync will automatically catch it and it will fix it with running in sync mode.
