The Apache Ignite github repository contains a number of runnable examples that illustrate various Ignite functionality.

Programming Languages

Ignite is available for Java, .NET/C#, C++ and other programming languages. The Java version provides the richest API. The .NET/C#, C++, Python, etc. languages may have limited functionality. To make the Ignite documentation intuitive for all application developers, we adhere to the following conventions:

  • The information provided in this documentation applies to all programming languages unless noted otherwise.

  • Code samples for different languages are provided in different tabs as shown below. For example, if you are a .NET developer, click on the .NET tab in the code examples to see .NET specific code.

    This is a place where an example of XML configuration is provided.
    Click on other tabs to view an equivalent programmatic configuration.
    Code sample in Java. Click on other tabs to view the same example in other languages.
    Code sample in .NET. Click on other tabs to view the same example in other languages.
    Code sample in C++. Click on other tabs to view the same example in other languages.
  • If there is no tab for a specific language, this most likely means that the functionality is not supported in that language.
