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.
You will learn how to download and install XAP.
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.
In this part of the tutorial we will introduce you to the different processing services you can run on top of the Space.
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.
