Distributed Java Databases Under the Hood: Main Components and Interactions Between Them

Distributed databases are becoming more and more popular. Social networks, online banking, and retail-—these are only a few examples of applications that might require horizontal scalability to achieve the performance, capacity, and availability that organizations require.
Using the Apache Ignite platform as a basis, we will identify major internal mechanisms that a typical distributed database uses to achieve the required goals. We will describe the minimal architecture of distributed data storage—-the main components and how these components work together.
During the session, we will create a simple (although fully workable) distributed cache in Java, almost from scratch. The cache will feature basic CRUD operations, as well as automatic out-of-the-box scalability--the must-have requirement for any distributed system.
