+<p>The Apache DataFusion PMC is pleased to announce version 0.9.0 of the <a
href="https://datafusion.apache.org/comet/";>Comet</a> subproject.</p>
+<p>Comet is an accelerator for Apache Spark that translates Spark physical
plans to DataFusion physical plans for
+improved performance and efficiency without requiring any code changes.</p>
+<p>This release covers approximately ten weeks of development work and is the
result of merging 139 PRs from 24
+contributors. See the <a
href="https://github.com/apache/datafusion-comet/blob/main/dev/changelog/0.9.0.md";>change
log</a> for more information.</p>
+<h2>Release Highlights</h2>
+<h3>Complex Type Support in Parquet Scans</h3>
+<p>Comet now supports complex types (Structs, Maps, and Arrays) when reading
Parquet files. This functionality is not
+yet available when reading Parquet files from Apache Iceberg.</p>
+<p>This functionality was only available in previous releases when manually
specifying one of the new experimental
+scan implementations. Comet now automatically chooses the best scan
implementation based on the input schema, and no
+longer requires manual configuration.</p>
+<h3>Complex Type Processing Improvements</h3>
+<p>Numerous improvements have been made to complex type support to ensure
Spark-compatible behavior when casting between
+structs and accessing fields within deeply nested types.</p>
+<h3>Shuffle Improvements</h3>
+<p>Comet now accelerates a broader range of shuffle operations, leading to
more queries running fully natively. In
+previous releases, some shuffle operations fell back to Spark to avoid some
known bugs in Comet, and these bugs have
+now been fixed.</p>
+<h3>New Features</h3>
+<p>Comet 0.9.0 adds support for the following Spark expressions:</p>
+<ul>
+<li>ArrayDistinct</li>
+<li>ArrayMax</li>
+<li>ArrayRepeat</li>
+<li>ArrayUnion</li>
+<li>BitCount</li>
+<li>BitNot</li>
+<li>Expm1</li>
+<li>MapValues</li>
+<li>Signum</li>
+<li>ToPrettyString</li>
+<li>map[]</li>
+</ul>
+<h3>Improved Spark SQL Test Coverage</h3>
+<p>Comet now passes 97% of the Spark SQL test suite, with more than 24,000
tests passing (based on testing against
+Spark 3.5.6). The remaining 3% of tests are ignored for various reasons, such
as being too specific to Spark
+internals, or testing for features that are not relevant to Comet, such as
whole-stage code generation, which
+is not needed when using a vectorized execution engine.</p>
+<p>This release contains numerous bug fixes to achieve this coverage,
including improved support for exchange reuse
+when AQE is enabled.</p>

+<h3>Memory & Performance Tracing</h3>
+<p>Comet now provides a tracing feature for analyzing performance and off-heap
versus on-heap memory usage. See the
+<a
href="https://datafusion.apache.org/comet/contributor-guide/tracing.html";>Comet
Tracing Guide</a> for more information.</p>
+<p><img alt="Comet Tracing" class="img-responsive"
src="/blog/images/comet-0.9.0/tracing.png" width="100%"/></p>
+<h3>Spark Compatibility</h3>
+<ul>
+<li>Spark 3.4.3 with JDK 11 & 17, Scala 2.12 & 2.13</li>
+<li>Spark 3.5.4 through 3.5.6 with JDK 11 & 17, Scala 2.12 & 2.13</li>
+<li>Experimental support for Spark 4.0.0 with JDK 17, Scala 2.13</li>
+</ul>
+<p>We are looking for help from the community to fully support Spark 4.0.0.
See <a href="https://github.com/apache/datafusion-comet/issues/1637";>EPIC:
Support 4.0.0</a> for more information.</p>
+<p>Note that Java 8 support was removed from this release because Apache Arrow
no longer supports it.</p>
+<h2>Getting Involved</h2>
+<p>The Comet project welcomes new contributors. We use the same <a
href="https://datafusion.apache.org/contributor-guide/communication.html#slack-and-discord";>Slack
and Discord</a> channels as the main DataFusion
+project and have a weekly <a
href="https://docs.google.com/document/d/1NBpkIAuU7O9h8Br5CbFksDhX-L9TyO9wmGLPMe0Plc8/edit?usp=sharing";>DataFusion
video call</a>.</p>
+<p>The easiest way to get involved is to test Comet with your current Spark
jobs and file issues for any bugs or
+performance regressions that you find. See the <a
href="https://datafusion.apache.org/comet/user-guide/installation.html";>Getting
Started</a> guide for instructions on downloading and installing
+Comet.</p>
+<p>There are also many <a
href="https://github.com/apache/datafusion-comet/contribute";>good first
issues</a> waiting for contributions.</p>

+<p>The Apache DataFusion PMC is pleased to announce version 0.9.0 of the
<a href="https://datafusion.apache.org/comet/">Comet</a>
subproject.</p>
+<p>Comet is an accelerator for Apache Spark that translates Spark
physical plans to DataFusion physical plans for
+improved performance and efficiency without requiring any code
changes.</p>
+<p>This release covers approximately ten weeks of development work and
is the result of merging 139 PRs from 24
+contributors. See the <a
href="https://github.com/apache/datafusion-comet/blob/main/dev/changelog/0.9.0.md">change
log</a> for more information.</p>
+<h2>Release Highlights</h2>
+<h3>Complex Type Support in Parquet Scans</h3>
+<p>Comet now supports complex types (Structs, Maps, and Arrays) when
reading Parquet files. This functionality is not
+yet available when reading Parquet files from Apache Iceberg.</p>
+<p>This functionality was only available in previous releases when
manually specifying one of the new experimental
+scan implementations. Comet now automatically chooses the best scan
implementation based on the input schema, and no
+longer requires manual configuration.</p>
+<h3>Complex Type Processing Improvements</h3>
+<p>Numerous improvements have been made to complex type support to
ensure Spark-compatible behavior when casting between
+structs and accessing fields within deeply nested types.</p>
+<h3>Shuffle Improvements</h3>
+<p>Comet now accelerates a broader range of shuffle operations, leading
to more queries running fully natively. In
+previous releases, some shuffle operations fell back to Spark to avoid some
known bugs in Comet, and these bugs have
+now been fixed.</p>
+<h3>New Features</h3>
+<p>Comet 0.9.0 adds support for the following Spark
expressions:</p>
+<ul>
+<li>ArrayDistinct</li>
+<li>ArrayMax</li>
+<li>ArrayRepeat</li>
+<li>ArrayUnion</li>
+<li>BitCount</li>
+<li>BitNot</li>
+<li>Expm1</li>
+<li>MapValues</li>
+<li>Signum</li>
+<li>ToPrettyString</li>
+<li>map[]</li>
+</ul>
+<h3>Improved Spark SQL Test Coverage</h3>
+<p>Comet now passes 97% of the Spark SQL test suite, with more than
24,000 tests passing (based on testing against
+Spark 3.5.6). The remaining 3% of tests are ignored for various reasons, such
as being too specific to Spark
+internals, or testing for features that are not relevant to Comet, such as
whole-stage code generation, which
+is not needed when using a vectorized execution engine.</p>
+<p>This release contains numerous bug fixes to achieve this coverage,
including improved support for exchange reuse
+when AQE is enabled.</p>
