+# Introduction
+
+[DataFusion](https://arrow.apache.org/datafusion/) is an embedded
+query engine which leverages the unique features of
+[Rust](https://www.rust-lang.org/) and [Apache
+Arrow](https://arrow.apache.org/) to provide a system that is high
+performance, easy to connect, easy to embed, and high quality.

This covers 4 months of development work
+and includes 122 commits from the following 28 distinct contributors.

Review comment:
I think the related PR link will be generated in the 6.0.0 Changelog.
But I feel this is a big change and great improvement so it might be helpful to
have a direct pointer(apache/arrow-datafusion#1010 and maybe the design doc as
well) in this blog.
