GridGain is Java based open source middleware for real time big data processing and analytics that scales up from one server to thousands of machines.

GridGain allows anyone easily develop, scale and manage compute and data intensive JVM based applications using Java, Scala or Groovy++. GridGain provides two major areas of functionality:

• Compute Grids

• In-Memory Data Grids

On top of that it provides the multitude of surrounding technologies many of which are frequently used by our clients on their own.

With GridGain your applications can:

• Work in a zero-deployment mode.

• Scale up or down based on demand.

• Cache distributed data in data grid.

• Co-locate data and computations.

• Run sql queries against cached data.

• Store and query JSON objects.

• Speed up task using MapReduce processing.

• Use distributed thread pools.

• Distribute the workload on the grid.

• Use distributed queues and atomics.

• Effectively exchange messages.

• Auto-discover all grid resources.

• Execute closures on the grid.

• Grid-enable java and scala code.

• …​ and much more

The best way to get started with GridGain is to look through examples. You can find all examples under examples folder right at where you installed GridGain. This folder contains examples for Java, Scala and some for Groovy.

You can simply run these examples from your favorite IDE or just command line. All examples have documentation on what they do and some basic configuration tips, if any needed.

We suggest to start with HelloWorld examples located at examples/java/org/gridgain/examples/helloworld folder. Getting started is easier with documentation on our Wiki

We spend significant amount of time on writing and maintaining Javadoc and Scaladoc for our product. All documentation is shipped with it and you can find it under javadoc, groovydoc, and scaladoc sub-folder respectively.

You can also find latest released Javadoc online: http://www.gridgain.com/javadoc40C/index.html

All scripts that you need to use on a regular basis can be found at bin sub-folder. To start a grid node with default configuration simply run bin/ggstart.sh or bin\ggstart.bat script - and you are in the grid!
