LoadStartingWith("books/1/chapters", null, 1, 10); You can even use this to match a part of a complex key. LoadStartingWith("phones/FL/904", null, 1, 10); The second parameter in the LoadStartingWith() method supports additional filtering by passing a pipe "|" delimited list of wildcards. " for matching on a single character just like searching a file system. While RavenDB supports other methods to retrieve lists of documents, using keys is the fastest method since RavenDB can go directly to the data store to load the documents.

Group }; } } Handling changing data over time So far, we have discussed documents that represent the current value of our data. But in many cases, data changes over time. How do we know what the previous state of the data was before it was updated? In relational databases, we often create history tables to store these old versions. Fortunately, RavenDB has a much cleaner approach. It has a Versioning bundle that adds support for automatically storing snapshots of documents every time they are changed.

Summary The design of your document data model is a key to performance and simplicity. But it requires thinking from a document perspective and not a relational one. Your documents should represent the natural boundaries within your application. The other tools such as indexes are there to aid in querying and are not meant to replace good document design. Next up, we will move beyond the session-based APIs covered in this chapter. These specialized APIs allow for further performance optimizations.
