Apache Ignite Quick Start Guide

Working with Data Grids

So far we learned about Apache Ignite architecture, caching styles, and clustering topology. Caching can be used in the UI layer to serve static content, and a JVM-level local cache can be configured to access the frequently used objects or query results. However, a distributed cache can act as an in-memory data store and move the data closer to the application. The data grid is an abstraction of a distributed cache as a data store. In this chapter, we will explore Apache Ignite's data grid concept and build a highly available web application with Ignite Session Clustering. All user sessions will be stored in a data grid and we will use the Ignite tools to view the user sessions in the grid. The following topics will ...
