 Apache Flink is a platform for efficient, distributed, general-purpose data processing.
 It features powerful programming abstractions in Java and Scala, a high-performance runtime, and
 automatic program optimization. It has native support for iterations, incremental iterations, and
 programs consisting of large DAGs of operations.

 If you quickly want to try out the system, please look at one of the available quickstarts. For
 a thorough introduction of the Flink API please refer to the
 [Programming Guide](programming_guide.html).

 ## Download

 You can download Flink from the [downloads]({{ site.FLINK_DOWNLOAD_URL }}) page
 of the [project website]({{ site.FLINK_WEBSITE_URL }}). This documentation is for version {{ site.FLINK_VERSION_SHORT }}. Be careful
 when picking a version, there are different versions depending on the Hadoop and/or
 HDFS version that you want to use with Flink. Please refer to [building](building.html) if you
 want to build Flink yourself from the source.

 In Version {{ site.FLINK_VERSION_SHORT}} the Scala API uses Scala {{ site.FLINK_SCALA_VERSION_SHORT }}. Please make
 sure to use a compatible version.
