Welcome to the Alluxio Community!

Alluxio (originally called Tachyon) started as an open source project from UC Berkeley’s AMPLab in 2014 by founder Haoyuan Li with the mission to orchestrate data for all data driven applications. We have now grown into a large and vibrant open source community! With over 1,200 contributors on Github and over 10,000 Slack community members, we were recognized as part of the Top 10 Most Critical Java Based Open Source Projects and named as one of the Top 100 Most Valuable Repositories on Github.

We invite you to read about, try out, use, and contribute to Alluxio, as well as to share your experience, feedback, suggestions and ideas!
