     <h1 class="entry-title">Apache Kudu 1.13.0 released</h1>
     <p class="meta">Posted 21 Sep 2020 by Attila Bukor</p>
   </header>
   <div class="entry-content">
     <p>The Apache Kudu team is happy to announce the release of Kudu 1.13.0!</p>

 <p>The new release adds several new features and improvements, including the
 following:</p>

 <!--more-->

 <ul>
   <li>Added table ownership support. All newly created tables are automatically
 owned by the user creating them. It is also possible to change the owner by
 altering the table. You can also assign privileges to table owners via Apache
 Ranger.</li>
   <li>An experimental feature is added to Kudu that allows it to automatically
 rebalance tablet replicas among tablet servers. The background task can be
 enabled by setting the <code class="language-plaintext highlighter-rouge">--auto_rebalancing_enabled</code> flag on the Kudu masters.
 Before starting auto-rebalancing on an existing cluster, the CLI rebalancer
 tool should be run first.</li>
   <li>Bloom filter column predicate pushdown has been added to allow optimized
 execution of filters which match on a set of column values with a
 false-positive rate. Support for Impala queries utilizing Bloom filter
 predicate is available yielding performance improvements of 19% to 30% in TPC-H
 benchmarks and around 41% improvement for distributed joins across large
 tables. Support for Spark is not yet available.</li>
   <li>ARM-based architectures are now supported.</li>
 </ul>

 <p>The above is just a list of the highlights, for a more complete list of new
 features, improvements and fixes please refer to the <a href="/releases/1.13.0/docs/release_notes.html">release
 notes</a>.</p>

 <p>The Apache Kudu project only publishes source code releases. To build Kudu
 1.13.0, follow these steps:</p>

 <ul>
   <li>Download the Kudu <a href="/releases/1.13.0">1.13.0 source release</a></li>
   <li>Follow the instructions in the documentation to build Kudu <a href="/releases/1.13.0/docs/installation.html#build_from_source">1.13.0 from
 source</a></li>
 </ul>

 <p>For your convenience, binary JAR files for the Kudu Java client library, Spark
 DataSource, Flume sink, and other Java integrations are published to the ASF
 Maven repository and are <a href="https://search.maven.org/search?q=g:org.apache.kudu%20AND%20v:1.13.0">now
 available</a>.</p>

 <p>The Python client source is also available on
 <a href="https://pypi.org/project/kudu-python/">PyPI</a>.</p>

 <p>Additionally, experimental Docker images are published to
 <a href="https://hub.docker.com/r/apache/kudu">Docker Hub</a>, including for AArch64-based
 architectures (ARM).</p>

	<ul>
	<li>Added table ownership support. All newly created tables are automatically
	owned by the user creating them. It is also possible to change the owner by
	altering the table. You can also assign privileges to table owners via Apache
	Ranger.</li>
	<li>An experimental feature is added to Kudu that allows it to automatically
	rebalance tablet replicas among tablet servers. The background task can be
	enabled by setting the <code class="language-plaintext highlighter-rouge">--auto_rebalancing_enabled</code> flag on the Kudu masters.
	Before starting auto-rebalancing on an existing cluster, the CLI rebalancer
	tool should be run first.</li>
	<li>Bloom filter column predicate pushdown has been added to allow optimized
	execution of filters which match on a set of column values with a
	false-positive rate. Support for Impala queries utilizing Bloom filter
	predicate is available yielding performance improvements of 19% to 30% in TPC-H
	benchmarks and around 41% improvement for distributed joins across large
	tables. Support for Spark is not yet available.</li>
	<li>ARM-based architectures are now supported.</li>
	</ul>

	<p>The above is just a list of the highlights, for a more complete list of new
	features, improvements and fixes please refer to the <a href="/releases/1.13.0/docs/release_notes.html">release
	notes</a>.</p>

	<p>The Apache Kudu project only publishes source code releases. To build Kudu
	1.13.0, follow these steps:</p>

	<ul>
	<li>Download the Kudu <a href="/releases/1.13.0">1.13.0 source release</a></li>
	<li>Follow the instructions in the documentation to build Kudu <a href="/releases/1.13.0/docs/installation.html#build_from_source">1.13.0 from
	source</a></li>
	</ul>

	<p>For your convenience, binary JAR files for the Kudu Java client library, Spark
	DataSource, Flume sink, and other Java integrations are published to the ASF
	Maven repository and are <a href="https://search.maven.org/search?q=g:org.apache.kudu%20AND%20v:1.13.0">now
	available</a>.</p>

	<p>The Python client source is also available on
	<a href="https://pypi.org/project/kudu-python/">PyPI</a>.</p>

	<p>Additionally, experimental Docker images are published to
	<a href="https://hub.docker.com/r/apache/kudu">Docker Hub</a>, including for AArch64-based
	architectures (ARM).</p>
