This release includes many important fixes and improvements.</p> + +<h2 id="netty-transport-improvements">Netty Transport Improvements</h2> + +<p>Storm's Netty-based transport has been overhauled to significantly improve performance through better utilization of thread, CPU, and network resources, particularly in cases where message sizes are small. Storm contributor Sean Zhong (<a href="https://github.com/clockfly";>@clockfly</a>) deserves a great deal of credit not only for discovering, analyzing, documenting and fixing the root cause, but also for persevering through an extended review process and promptly addressing all concerns.</p> + +<p>Those interested in the technical details and evolution of this patch can find out more in the <a href="https://issues.apache.org/jira/browse/STORM-297";>JIRA ticket for STORM-297</a>.</p> + +<p>Sean also discovered and fixed an <a href="https://issues.apache.org/jira/browse/STORM-342";>elusive bug</a> in Storm's usage of the Disruptor queue that could lead to out-of-order or lost messages. </p> + +<p>Many thanks to Sean for contributing these important fixes.</p> + +<h2 id="storm-ui-improvements">Storm UI Improvements</h2> + +<p>This release also includes a number of improvements to the Storm UI service. Contributor Sriharsha Chintalapani(<a href="https://github.com/harshach";>@harshach</a>) added a REST API to the Storm UI service to expose metrics and operations in JSON format, and updated the UI to use that API.</p> + +<p>The new REST API will make it considerably easier for other services to consume availabe cluster and topology metrics for monitoring and visualization applications. Kyle Nusbaum (<a href="https://github.com/knusbaum";>@knusbaum</a>) has already leveraged the REST API to create a topology visualization tool now included in Storm UI and illustrated in the screenshot below.</p> + +<p> </p> + +<p><img src="/images/ui_topology_viz.png" alt="Storm UI Topology Visualization"></p> + +<p> </p> + +<p>In the visualization, spout components are represented as blue, while bolts are colored between green and red depending on their associated capacity metric. The width of the lines between the components represent the flow of tuples relative to the other visible streams. </p> + +<h2 id="kafka-spout">Kafka Spout</h2> + +<p>This is the first Storm release to include official support for consuming data from Kafka 0.8.x. In the past, development of Kafka spouts for Storm had become somewhat fragmented and finding an implementation that worked with certain versions of Storm and Kafka proved burdensome for some developers. This is no longer the case, as the <code>storm-kafka</code> module is now part of the Storm project and associated artifacts are released to official channels (Maven Central) along with Storm's other components.</p> + +<p>Thanks are due to GitHub user <a href="">@wurstmeister</a> for picking up Nathan Marz' original Kafka 0.7.x implementation, updating it to work with Kafka 0.8.x, and contributing that work back to the Storm community.</p> + +<p>The <code>storm-kafka</code> module can be found in the <code>/external/</code> directory of the source tree and binary distributions. The <code>external</code> area has been set up to contain projects that while not required by Storm, are often used in conjunction with Storm to integrate with some other technology. Such projects also come with a maintenance committment from at least one Storm committer to ensure compatibility with Storm's main codebase as it evolves.</p> + +<p>The <code>storm-kafka</code> dependency is available now from Maven Central at the following coordinates:</p> +<div class="highlight"><pre><code class="language-text" data-lang="text">groupId: org.apache.storm +artifactId: storm-kafka +version: 0.9.2-incubating +</code></pre></div> +<p>Users, and Scala developers in particular, should note that the Kafka dependency is listed as <code>provided</code>. This allows users to choose a specific Scala version as described in the <a href="https://github.com/apache/incubator-storm/tree/v0.9.2-incubating/external/storm-kafka";>project README</a>.</p> + +<h2 id="storm-starter-and-examples">Storm Starter and Examples</h2> + +<p>Similar to the <code>external</code> section of the codebase, we have also added an <code>examples</code> directory and pulled in the <code>storm-starter</code> project to ensure it will be maintained in lock-step with Storm's main codebase.</p> + +<p>Thank you to Storm committer Michael G. Noll for his continued work in maintaining and improving the <code>storm-starter</code> project.</p> + +<h2 id="plugable-serialization-for-multilang">Plugable Serialization for Multilang</h2> + +<p>In previous versions of Storm, serialization of data to and from multilang components was limited to JSON, imposing somewhat of performance penalty. Thanks to a contribution from John Gilmore (<a href="https://github.com/jsgilmore";>@jsgilmore</a>) the serialization mechanism is now plugable and enables the use of more performant serialization frameworks like protocol buffers in addition to JSON.</p> + +<h2 id="thanks">Thanks</h2> + +<p>Special thanks are due to all those who have contributed to Storm -- whether through direct code contributions, documentation, bug reports, or helping other users on the mailing lists. Your efforts are much appreciated.</p> + +<h2 id="changelog">Changelog</h2> + +<ul> +<li>STORM-352: [storm-kafka] PartitionManager does not save offsets to ZooKeeper</li> +<li>STORM-66: send taskid on

This release includes 100 new fixes and improvements from 62 individual contributors.</p> + +<h2 id="improved-kafka-integration">Improved Kafka Integration</h2> + +<p>Apache Storm has supported <a href="http://kafka.apache.org/";>Apache Kafka</a> as a streaming data source since version 0.9.2-incubating. Version 0.9.3 brings a number of improvements to the Kafka integration including the ability to write data to one or more Kafka clusters and topics.</p> + +<p>The ability to both read from and write to Kafka further unlocks potential of the already powerful combination of Storm and Kafka. Storm users can now use Kafka as a source of and destination for streaming data. This allows for inter-topology communication, topology chaining, combining spout/bolt-based topologies with Trident-based data flows, and integration with any external system that supports data ingest from Kafka.</p> + +<p>More information about Storm's Kafka integration can be found in the <a href="https://github.com/apache/storm/blob/v0.9.3/external/storm-kafka/README.md";>storm-kafka project documentation</a>.</p> + +<h2 id="hdfs-integration">HDFS Integration</h2> + +<p>Many stream processing use cases involve storing data in HDFS for further analysis and offline (batch) processing. Apache Stormâs HDFS integration consists of several bolt and Trident state implementations that allow topology developers to easily write data to HDFS from any Storm topology. </p> + +<p>More information about Storm's HDFS integration can be found in the <a href="https://github.com/apache/storm/tree/v0.9.3/external/storm-hdfs";>storm-hdfs project documentation</a>.</p> + +<h2 id="hbase-integration">HBase Integration</h2> + +<p>Apache Stormâs HBase integration includes a number of components that allow Storm topologies to both write to and query HBase in real-time. Many organizations use Apache HBase as part of their big data strategy for batch, interactive, and real-time workflows. Stormâs HBase integration allows users to leverage data assets in HBase as streaming queries, as well as using HBase as a destination for streaming computation results.</p> + +<p>More information about Storm's HBase integration can be found in the <a href="https://github.com/apache/storm/tree/v0.9.3/external/storm-hbase";>storm-hbase project documentation</a>.</p> + +<h2 id="reduced-dependency-conflicts">Reduced Dependency Conflicts</h2> + +<p>In previous Storm releases, it was not uncommon for users' topology dependencies to conflict with the libraries used by Storm. In Storm 0.9.3 several dependency packages that were common sources of conflicts have been package-relocated (shaded) to avoid this situation. Developers are free to use the Storm-packaged versions, or supply their own version. </p> + +<p>The following table lists the dependency package relocations:</p> + +<table><thead> +<tr> +<th style="text-align: left">Dependency</th> +<th style="text-align: left">Original Package</th> +<th style="text-align: left">Storm Package</th> +</tr> +</thead><tbody> +<tr> +<td style="text-align: left">Apache Thrift</td> +<td style="text-align: left"><code>org.apache.thrift</code></td> +<td style="text-align: left"><code>org.apache.thrift7</code></td> +</tr> +<tr> +<td style="text-align: left">Netty</td> +<td style="text-align: left"><code>org.jboss.netty</code></td> +<td style="text-align: left"><code>org.apache.storm.netty</code></td> +</tr> +<tr> +<td style="text-align: left">Google Guava</td> +<td style="text-align: left"><code>com.google.common</code></td> +<td style="text-align: left"><code>org.apache.storm.guava</code></td> +</tr> +<tr> +<td style="text-align: left"></td> +<td style="text-align: left"><code>com.google.thirdparty</code></td> +<td style="text-align: left"><code>org.apache.storm.guava.thirdparty</code></td> +</tr> +<tr> +<td style="text-align: left">Apache HTTPClient</td> +<td style="text-align: left"><code>org.apache.http</code></td> +<td style="text-align: left"><code>org.apache.storm.http</code></td> +</tr> +<tr> +<td style="text-align: left">Apache ZooKeeper</td> +<td style="text-align: left"><code>org.apache.zookeeper</code></td> +<td style="text-align: left"><code>org.apache.storm.zookeeper</code></td> +</tr> +<tr> +<td style="text-align: left">Apache Curator</td> +<td style="text-align: left"><code>org.apache.curator</code></td> +<td style="text-align: left"><code>org.apache.storm.curator</code></td> +</tr> +</tbody></table> + +<h2 id="multi-lang-improvements">Multi-Lang Improvements</h2> + +<p>Apache Storm 0.9.3 includes a new <a href="http://nodejs.org";>Node.js</a> multi-lang implementation that allows developers to write spouts and bolts in JavaScript.</p> + +<p>In addition to the Node.js implementation, the multi-lang protocol has been substantially improved in terms of robustness and error handling capabilities. As a result, <strong>the multi-lang API has changed in a non-backward-compatible way</strong>. Users with existing multi-lang topologies should consult the Python, Ruby, and JavaScript multi-lang examples to determine the impact prior to upgrading.</p> + +<h2 id="thanks">Thanks</h2> + +<p>Special thanks are due to all those who have contributed to Storm -- whether through direct code contributions, documentation, bug reports, or helping other users on the mailing lists.
