Build Status

Welcome to XAP

XAP is a distributed, highly-scalable, In Memory Data Grid.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.


Running XAP requires Java 6 or later.

Building XAP requires Java 8 or later (The core requires Java 6, but some optional components and integrations depend on features from higher Java version, so building the entire product requires Java 8).

In addition you'll need Maven to build the project.


To build the entire product, simply run the build script (either .sh or .bat) located at the root folder. This builds all the modules and generates a product zip file at /xap-dist/target.

If you're interested in building specific modules, switch to the relevant folder and use maven to build that module.

Hello World

If this is your first experience with XAP, we recommend you check out the hello-world example located at the examples folder. Once you're done, check out the docs to learn more, and if you have any questions visit our community forum.


Please read for details on our code of conduct, and the process for submitting pull requests to us.


We're using standard versioning schema ( The master branch reflects the current state, and each release is tagged in git (tags on this repository).


Here's the list of contributors who participated in this project.

Note, however, that during our recent efforts to open source XAP, we had to drop the history, so this list only reflect very recent contributors. We'd like to take this opportunity to honor all past GigaSpaces developers whose contribution is now anonymous - we couldn't have done this without you!
