+# Introduction
+
+[Ballista][ballista] is an Arrow-native distributed SQL query engine

+## Release Highlights
+
+The release notes below are not exhaustive and only expose selected highlights
of the release. Many other bug fixes
+and improvements have been made: we refer you to the [complete
changelog][changelog].
+
+### Support for Cloud Object Stores and Distributed File Systems
+
+This is the first release of Ballista to have documented support for querying
data from distributed file systems and
+object stores. Currently, S3 and HDFS are supported. Support for Google Cloud
Storage and Azure Blob Storage is planned
+for the next release.
+
+### Flight SQL & JDBC support
+
+The Ballista scheduler now implements the [Flight SQL protocol][flight-sql],
enabling any compliant Flight SQL client
+to connect to and run queries against a Ballista cluster.
+
+The Apache Arrow Flight SQL JDBC driver can be used to connect Business
Intelligence tools to a Ballista cluster.
+
+### Python Bindings
+
+It is now possible to connect to a Ballista cluster from Python and execute
queries using both the DataFrame and SQL
+interfaces.
+
+### Scheduler Web User Interface and REST API
+
+The scheduler now has a web user interface for monitoring queries. It is also
possible to view graphical query plans
+that show how the query was executed, along with metrics.
+

+
+The REST API that powers the user interface can also be accessed directly.
+
+### Simplified Kubernetes Deployment
+
+Ballista now provides a [Helm chart][helm-chart] for simplified Kubernetes
deployment.
+
+### Performance and Scalability
+
+We continue to use benchmarks derived from TPC-H to compare performance with
other query engines and identify
+query optimizations that should be implemented. With the 0.9.0 release, we see
that some queries are now more than 10x
+faster than Apache Spark at the scale factor we are currently testing at.
+

+
+More optimizations are planned for the 0.10.0 release. See the [tracking
issue][optimizations] for details.
Review Comment:
I plan on removing this section since I have no confidence that all of the
queries are working correctly
