layout: global title: Home custom_title: Apache Spark™ - Unified Analytics Engine for Big Data description: Apache Spark is a unified analytics engine for big data processing, with built-in modules for streaming, SQL, machine learning and graph processing. type: page navigation: weight: 1 show: true

<p class="lead">
  Run workloads 100x faster.
</p>

<p>
  Apache Spark achieves high performance for both batch and streaming data, using a state-of-the-art DAG scheduler, a query optimizer, and a physical execution engine.
</p>

<p class="lead">
  Write applications quickly in Java, Scala, Python, R, and SQL.
</p>

<p>
  Spark offers over 80 high-level operators that make it easy to build parallel apps.
  And you can use it <em>interactively</em>
  from the Scala, Python, R, and SQL shells.
</p>

<p class="lead">
  Combine SQL, streaming, and complex analytics.
</p>

<p>
  Spark powers a stack of libraries including
  <a href="{{site.baseurl}}/sql/">SQL and DataFrames</a>, <a href="{{site.baseurl}}/mllib/">MLlib</a> for machine learning,
  <a href="{{site.baseurl}}/graphx/">GraphX</a>, and <a href="{{site.baseurl}}/streaming/">Spark Streaming</a>.
  You can combine these libraries seamlessly in the same application.
</p>

<p class="lead">
  Spark runs on Hadoop, Apache Mesos, Kubernetes, standalone, or in the cloud. It can access diverse data sources.
</p>

<p>
  You can run Spark using its <a href="{{site.baseurl}}/docs/latest/spark-standalone.html">standalone cluster mode</a>,
