XAP Basics for .NET


This section provides some hands-on examples to demonstrate the core concepts and APIs of the XAP in-memory data grid. The tutorials are geared toward architects and developers who want to build scaled-out applications with XAP.

Installation
You will learn how to download and install XAP.

XAP.NET in 5 minutes
This tutorial explains how to deploy and use a XAP Data Grid from a .NET client application.

Interacting with the Space
In this part of the tutorial we will demonstrate how to create a Space and how you can interact with it. We will also demonstrate how you can improve your space search performance by using indexes and returning partial results.

Deploying a Space
In the previous section you have learned about XAP’s capabilities as a data store. In this part of the tutorial we will show you how you can deploy an In Memory Data Grid (IMDG) that provides scalability and failover.

Distributed Processing
In this part of the tutorial we will introduce you to the different processing services you can run on top of the Space.

Event-Driven Processing
The Spaces Messaging and Events support provides messaging handlers that simplify event driven programming.

Creating a Processing Unit
The PU is the fundamental unit of deployment in XAP. The PU itself runs within a Processing Unit Container and is deployed onto the Service Grid. Once a PU is deployed, a PU instance is the actual runtime entity.

Transactions and Concurrency
In this part of the tutorial we will introduce you to the transaction processing capabilities of XAP.

Persist to Database
There are many situations where space data needs to be persisted to permanent storage and retrieved from it.
