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.

Paging a query's results


Paging a query result is the process of returning the results of a query in smaller subsets of data, or pages. Nowadays implementing pagination is a very common scenario for displaying results to a user in small, easy to manage chunks.

RavenDB allows query's result pagination and supports both Skip and Take LINQ operators, making paging through a collection easy. To perform paging you will call the Take and Skip operators on the Query object to return a given number of elements and/or to skip over a given number of elements and then return the remainder.

As RavenDB is safe by default, it protects itself and user applications from overload scenarios and limits the number of documents to be returned to the client from the server. In large dataset scenarios it makes paging mandatory. This means that we need to ensure that we limit the result sets to reasonable sizes.

By default, the number of documents on the client side is 128 (but you can change that) and 1024 for the...
