Overview of this book

RavenDB is a second generation document database written in .NET, offering a flexible data model designed to address requirements coming from real-world systems. It is different from the other document databases around, as with RavenDB you can get up and running in a few minutes, and that includes grasping all the basics. It allows you to build high-performance, low-latency applications with ease and efficiency.RavenDB 2.x Beginner's Guide introduces RavenDB concepts and teaches you everything, right from installing RavenDB, to creating documents, and querying indexes. This book will help you take advantage of powerful, document-oriented NoSQL databases and build a solid foundation on which you can create your .NET applications. This book presents RavenDB, the .NET document-oriented NoSQL database, through a series of clear and practical exercises that will help you to take advantage of this database server. The book starts off with an introduction to RavenDB and its Management Studio. You will then move ahead and learn how to quickly and efficiently build high performance, NoSQL document-oriented .NET applications using the .NET client API or the HTTP REST API. Next, Dynamic and static indexes that use map/reduce to process datasets are covered. You will then see how to create and query these indexes, with the help of detailed examples. You will also learn how to deploy your RavenDB server in a production environment and how to optimize and secure it.With numerous practical examples, RavenDB 2.x Beginner's Guide teaches you everything you need to know for building high performance .NET document-oriented NoSQL databases.

Time for action – explicitly waiting for a non-stale index result


You will add a new code snippet to the Main() method of the RavenDB_Ch04 project to tell RavenDB to wait for a non-stale result.

  1. Open the RavenDB_Ch04 project in Visual Studio.

  2. Add the following code to the Main() method:

  3. Save all the files, build and run the solution.

What just happened?

You added the necessary code to the Main() method to instruct RavenDB to explicitly wait for a non-stale index result.

In order to do that, you call the Customize() method on the Query object and call the WaitForNonStaleResultsAsOfNow() function within a lambda expression. This function takes a TimeSpan parameter to specify the time-out waiting delay. In this code snippet, we had specified 5 seconds as the time-out delay.

Note

Waiting for a non-stale index result is for use only for testing and learning purposes. It is strongly discouraged in a production environment.
