Part 3, Import a Database

This topic is a hands/on introduction to GigaSpaces XAP. It is designed to give you a quick, easy introduction to the GigaSpaces system.

This introduction consists of four parts:

Part 1 — Setting the Environment — Prepare a database that will be imported into GigaSpaces. In these examples, we will use data from the PostgreSQL database.
Part 2 — Launch Ops Manager — Run and view the GigaSpaces user interface.
4 Part 3 — Import a Database (this topic) — Bring data from the PostgreSQL database into the GigaSpaces in-memory data grid, and run some SQL operations.
Part 4 — Convert a Program — Explore the tools to convert a Java program from JDBC access to the GigaSpaces Java API.

The following steps will show you how to copy data from the PostgreSQL database into the GigaSpaces in-memory data grid. You will also see the resulting GigaSpace service and Space, and will be able to perform SQL operations on the data.
