+<p>The Apache DataFusion PMC is pleased to announce version 0.10.0 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 183 PRs from 26
+contributors. See the <a
href="https://github.com/apache/datafusion-comet/blob/main/dev/changelog/0.10.0.md";>change
log</a> for more information.</p>
+<h2 id="release-highlights">Release Highlights<a class="headerlink"
href="#release-highlights" title="Permanent link">¶</a></h2>
+<h3 id="improved-support-for-apache-iceberg">Improved Support for Apache
Iceberg<a class="headerlink" href="#improved-support-for-apache-iceberg"
title="Permanent link">¶</a></h3>
+<p>It is now possible to use Comet with Apache Iceberg 1.8.1 to accelerate
reads of Iceberg Parquet tables. Please refer to Comet's <a
href="https://datafusion.apache.org/comet/user-guide/latest/iceberg.html";>Iceberg
Guide</a> for information on building Iceberg with Comet.</p>
+<h3 id="improved-spark-400-support">Improved Spark 4.0.0 Support<a
class="headerlink" href="#improved-spark-400-support" title="Permanent
link">¶</a></h3>
+<p>Comet no longer falls back to Spark for all queries when ANSI mode is
enabled (which is the default in Spark 4.0.0).
+Instead, Comet will now only fall back to Spark for arithmetic and aggregates
expressions that support ANSI mode.</p>
+<p>Setting <code>spark.comet.ansi.ignore=true</code> will override this
behavior and force these expressions to continue to be
+accelerated by Comet. Full support for ANSI mode will be available in a future
release.</p>
+<p>Comet will now use the <code>native_iceberg_compat</code> scan for Spark
4.0.0 in most cases, which supports reading complex types.</p>
+<h3 id="new-functionality">New Functionality<a class="headerlink"
href="#new-functionality" title="Permanent link">¶</a></h3>
+<p>The following SQL functions are now supported:</p>
+<ul>
+<li><code>array_min</code></li>
+<li><code>map_entries</code></li>
+<li><code>map_from_array</code></li>
+<li><code>randn</code></li>
+<li><code>from_unixtime</code></li>
+<li><code>monotonically_increasing_id</code></li>
+<li><code>spark_partition_id</code></li>
+<li><code>try_add</code></li>
+<li><code>try_divide</code></li>
+<li><code>try_mod</code></li>
+<li><code>try_multiply</code></li>
+<li><code>try_subtract</code></li>
+</ul>
+<p>Other new features include:</p>
+<ul>
+<li>Support for array literals</li>
+<li>Support for limit with offset</li>
+</ul>
+<h3 id="ux-improvements">UX Improvements<a class="headerlink"
href="#ux-improvements" title="Permanent link">¶</a></h3>
+<ul>
+<li>Improved reporting of reasons why Comet cannot accelerate some operators
and expressions</li>
+<li>New <code>spark.comet.logFallbackReasons.enabled</code> configuration
setting for logging all fallback reasons</li>
+<li>CometScan nodes in the physical plan now show which scan implementation is
being used (<code>native_comet</code>,
+<code>native_datafusion</code>, or <code>native_iceberg_compat</code>)</li>
+</ul>
+<h3 id="bug-fixes">Bug Fixes<a class="headerlink" href="#bug-fixes"
title="Permanent link">¶</a></h3>
+<ul>
+<li>Improved memory safety for FFI transfers</li>
+<li>Fixed a double-free issue in the shuffle unified memory pool</li>
+<li>Fixed an FFI issue with non-zero offsets</li>
+<li>Fixed an issue with buffered reads from HDFS </li>
+</ul>
+<h3 id="benchmarking">Benchmarking<a class="headerlink" href="#benchmarking"
title="Permanent link">¶</a></h3>
+<p>Benchmarking scripts for benchmarks based on TPC-H and TPS-DS are now
available in the repository under <code>dev/benchmarks</code>.</p>
+<h3 id="documentation-updates">Documentation Updates<a class="headerlink"
href="#documentation-updates" title="Permanent link">¶</a></h3>
+<ul>
+<li>The documentation for supported <a
href="https://datafusion.apache.org/comet/user-guide/latest/operators.html";>operators</a>
and <a
href="https://datafusion.apache.org/comet/user-guide/latest/expressions.html";>expressions</a>
is now more complete, and Spark-compatibility status
+ per operator/expression is now documented.</li>
+<li>The documentation now contains a <a
href="https://datafusion.apache.org/comet/contributor-guide/roadmap.html";>roadmap</a>
section.</li>
+<li>New <a
href="https://datafusion.apache.org/comet/gluten_comparison.html";>guide</a>
comparing Comet with Apache Gluten (incubating) + Velox</li>
+<li>User guides are now available for multiple Comet versions</li>
+</ul>
+<h3 id="spark-compatibility">Spark Compatibility<a class="headerlink"
href="#spark-compatibility" title="Permanent link">¶</a></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>
+<h2 id="getting-involved">Getting Involved<a class="headerlink"
href="#getting-involved" title="Permanent link">¶</a></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 0.10.0 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 183 PRs from 26
+contributors. See the <a

href="#getting-involved" title="Permanent link">¶</a></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

+<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

issues</a> waiting for contributions.</p></content><category
