Introducing Chauffeur, a new classy way to delivery changes around Umbraco instances.
If you've read my article on Understanding LINQ to Umbraco (and if you haven't you really should go do that) you'll know that LINQ to Umbraco does have the scaffolding for doing full CRUD operations. But with CRUD it is up to the underlying
UmbracoDataProvider implementation to support.
Because the OOTB
UmbracoDataProvider instance, the
NodeDataProvider is only concerned with how to access the in-memory cache so having full CRUD doesn't make sense.
This is where the
DocumentDataProvider fits in; like its name suggests it is designed to work with the Umbraco Document API, which is responsible for performing CRUD operations. So the ultimate goal of the
DocumentDataProvider will be to provide full CRUD operations against the Umbraco database.
DocumentDataProvider vs NodeDataProvider
So if the goal of the
DocumentDataProvider is to provide full CRUD where will that leave
NodeDataProvider? Well they should still sit side-by-side. For your common usage you should still use the
NodeDataProvider, this will only be interacting with published content, and the in-memory cache. The
DocumentDataProvider on the other hand will be interacting with the Document API, this means that it'll be tied to the SQL instance, and doing read operations will suffer from the same performance limitations that you can find from the Document API. There will be caching built into the
DocumentDataProvider, but by-and-large there will be limits to how that can help.
