<h3>Project History</h3>


<p>
Spark started as a research project at the <a href="https://amplab.cs.berkeley.edu">UC Berkeley AMPLab</a>
in 2009, and was open sourced in early 2010.
Many of the ideas behind the system are presented in various
<a href="{{site.url}}research.html">research papers</a>.
</p>

<p>
After being released, Spark grew a developer community on GitHub and moved to Apache in 2013.
A wide range of contributors now develop the project (over 400 developers from 100 companies).
