This strategy handles column additions and deletions better than the `check_cols` strategy.

#### Ensure your unique key is really unique
The unique key is used by dbt to match rows up, so it's extremely important to make sure this key is actually unique! If you're snapshotting a source, I'd recommend adding a uniqueness test to your source ([example](https://github.com/fishtown-analytics/jaffle_shop/blob/demo/master/models/staging/jaffle_shop/jaffle_shop.yml#L22)).

Snapshots cannot be rebuilt. As such, it's a good idea to put snapshots in a separate schema so end users know they are special. From there, you may want to set different privileges on your snapshots compared to your models, and even run them as a different user (or role, depending on your warehouse) to make it very difficult to drop a snapshot unless you really want to.
