- <title>Storm 1.2.0 Released</title>
- <description><p>The Apache Storm community is pleased to announce that version 1.2.0 has been released and is available from <a href="/downloads.html">the downloads page</a>.</p>
-
-<p>This is a maintenance release that includes a number of important bug fixes that improve Storm&#39;s performance, stability and fault tolerance. We encourage users of previous versions to upgrade to this latest release.</p>
-
-<h2 id="apache-kafka-integration-improvements">Apache Kafka Integration Improvements</h2>
-
-<p>This release includes many improvements to Storm&#39;s Kafka integration that improve stability, ease configuration, and expose new features. More details can be found in the
-<a href="/releases/1.2.0/storm-kafka-client.html">Kafka client documentation</a></p>
-
-<h2 id="new-metrics-reporting-api">New Metrics Reporting API</h2>
-
-<p>This release introduces a new metrics system for reporting internal statistics (e.g. acked, failed, emitted, transferred, disruptor queue metrics, etc.) as well as a new API for user defined metrics based on the popular <a href="">Dropwizard Metrics library</a>. Storm includes reporters for gathering metrics data with Ganglia, Graphite, JMX, CSV and the console. Additional metrics systems can be integrated by extending the <code>org.apache.storm.metrics2.reporters.ScheduledStormReporter</code> class. Additional details can be found in the <a href="/releases/1.2.0/metrics_v2.html">metrics documentation</a>.</p>
-
-<h2 id="thanks">Thanks</h2>
-
-<p>Special thanks are due to all those who have contributed to Apache Storm -- whether through direct code contributions, documentation, bug reports, or helping other users on the mailing lists. Your efforts are much appreciated.</p>

- <title>Storm 1.1.0 released</title>
- <description><p>The Apache Storm community is pleased to announce that version 1.1.0 has been released and is available from <a href="/downloads.html">the downloads page</a>.</p>
-
-<p>This release represents a major milestone in the evolution of Apache Storm, and includes a large number of new features, usability and performance improvements, some of which are highlighted below.</p>
-
-<h2 id="streaming-sql">Streaming SQL</h2>
-
-<p>Storm 1.1.0 supports native Streaming SQL, powered by <a href="http://calcite.apache.org">Apache Calcite</a>, that allows users to run SQL queries over streaming data as well update external systems and data stores such as <a href="http://hive.apache.org">Apache Hive</a>. To deploy an SQL-based topology users define the SQL query in a text file and use the <code>storm sql</code> command to submit the resulting topology to a Storm cluster. Behind the scenes Storm will compile the SQL into a Trident topology and run it on the cluster.</p>
-
-<p>Storm&#39;s SQL support includes the following features:</p>
-
-<ul>
-<li>Streaming from/to external sources including Apache Kafka, HDFS, MongoDB, and Redis</li>
-<li>Tuple filtering</li>
-<li>Projections</li>
-<li>User-defined paralallism of generated components</li>
-<li>User Defined Functions (UDFs)</li>
-<li>CSV, TSV, and Avro input/output formats</li>
-<li>Extensibility to additional data sources via the <code>ISqlTridentDataSource</code> interface</li>
-</ul>
-
-<p>For more information about Storm&#39;s SQL support including examples, refer to the following resources:</p>
-
-<ul>
-<li><a href="/releases/1.1.0/storm-sql.html">Storm SQL Overview</a></li>
-<li><a href="/releases/1.1.0/storm-sql-example.html">Storm SQL Examples</a></li>
-<li><a href="/releases/1.1.0/storm-sql-reference.html">Storm SQL Reference</a></li>
-</ul>
-
-<h2 id="apache-kafka-integration-improvements">Apache Kafka Integration Improvements</h2>
-
-<p>In addition to the traditional support for Kafka version 0.8/0.9 based on the Kafka simple consumer, Storm includes support for Kafka 0.10 and later based on the new Kafka consumer API. Storm&#39;s integration with Kafka 0.10 and later version is highly flexible and extensible, some of the features include:</p>
-
-<ul>
-<li>Enhanced configuration API</li>
-<li>Fine-grained offset control (at start and after failure)</li>
-<li>Consumer group support</li>
-<li>Plugable record translators</li>
-<li>Wildcard topics</li>
-<li>Multiple stream support</li>
-<li>Manual partition control</li>
-<li>Kafka security support</li>
-</ul>
-
-<p>For more information on Storm&#39;s Kafka integration please refer to the following documentation:</p>
-
-<ul>
-<li><a href="/releases/1.1.0/storm-kafka-client.html">Kafka Integration (0.10 and later)</a></li>
-<li><a href="/releases/1.1.0/storm-kafka.html">Kafka Integration (0.8/0.9)</a></li>
-</ul>
-
-<h2 id="pmml-predictive-model-markup-language-support">PMML (Predictive Model Markup Language) Support</h2>
-
-<p>In order to better support machine learning use cases, Storm now includes support for executing PMML models in topoliges via a generic PMML bolt. The <code>PMMLPredictorBolt</code> allows users to specify a model, the raw input, and the resulting streams and output fields. At runtime the bolt will process incoming raw data, execute the model with the given input, and output tuples with scores for predicted fields and output fields.</p>
-
-<p>More information on Storm&#39;s PMML support can be found <a href="https://github.com/apache/storm/blob/v1.1.0/external/storm-pmml/README.md">here</a>.</p>
-
-<h2 id="druid-integration">Druid Integration</h2>
-
-<p><a href="http://druid.io">Druid</a> is a scalable, high-performance, column oriented, distributed data store popular for real time analytics use cases. Storm 1.1.0 introduces a Storm bolt and Trident state implementations for streaming data into a Druid data store.</p>
-
-<p>Documentation for Storm&#39;s Druid integration can be found <a href="https://github.com/apache/storm/blob/v1.1.0/external/storm-druid/README.md">here</a>.</p>
-
-<h2 id="opentsdb-integration">OpenTSDB Integration</h2>
-
-<p><a href="http://opentsdb.net">OpenTSDB</a> is a highly scalable time series database based on Apache HBase. Storm 1.1.0 adds a Storm bolt and Trident state implementations for writing data to OpenTSDB. Storm&#39;s OpenTSDB integration gives users fine-grained control over how Storm tuples map to OpenTSDB data structure by providing a simple interface (<code>ITupleOpenTsdbDatapointMapper</code>) that performs the translation.</p>
-
-<p>Move information about Storm&#39;s OpenTSDB integration can be found <a href="https://github.com/apache/storm/blob/v1.1.0/external/storm-opentsdb/README.md">here</a>.</p>
-
-<h2 id="aws-kinesis-support">AWS Kinesis Support</h2>
-
-<p>For users looking to integrate with Amazon&#39;s Kinesis service, Storm 1.1.0 now includes a spout for consuming message streams from Kinesis. Like most of Storm&#39;s external system integration components, the Kinesis spout provides a simple interface (<code>RecordToTupleMapper</code>)for controlling how Kinesis messages are translated to Storm tuples. The Kinesis spout provides an additional interface (<code>FailedMessageRetryHandler</code>) that allows users to customize the Spout&#39;s failure handling logic.</p>
-
-<p>Documentation for the Kinesis spout can be found <a href="https://github.com/apache/storm/blob/v1.1.0/external/storm-kinesis/README.md">here</a>.</p>
-
-<h2 id="hdfs-spout">HDFS Spout</h2>
-
-<p>Storm&#39;s HDFS integration now includes a spout that continuously streams data from the HDFS filesystem. Storm&#39;s HDFS spout monitors a configurable directory for new files and feeds that data into a topology. When the spout has completed processing a file, it will be moved to the configured archive directory. In the event a file is corrupt or is otherwise not processable, the corresponding file will be moved to a specific directory. Parallelism of the spout is made possible through a locking mechanism that ensures each file is &quot;owned&quot; by a single spout instance. The HDFS spout supports connecting to HDFS instances that are secured with Kerberos authentication.</p>
-
-<p>More information on using the HDFS spout can be found in the <a href="https://github.com/apache/storm/blob/v1.1.0/external/storm-hdfs/README.md">Storm HDFS Documentation</a></p>
-
-<h2 id="flux-improvements">Flux Improvements</h2>
-
-<p>Flux is a framework and set of utilities that allow users to declaratively define Storm topologies and avoid hard-coding configuration values in topology components. Storm 1.1.0 introduces the following enhancements to the Flux framework:</p>
-
-<ul>
-<li>Flux topology visualization in Storm UI</li>
-<li>Support for Stateful bolts and windowing</li>
-<li>Support for named streams</li>
-<li>Support for lists of references</li>
-</ul>
-
-<p>More information about Flux can be found in the <a href="/releases/1.1.0/flux.html">Flux documentation</a>.</p>
-
-<h2 id="topology-deployment-enhancements">Topology Deployment Enhancements</h2>
-
-<p>In previous versions of Storm it was typically necessary to include all topology dependences in a shaded &quot;uber jar,&quot; or by making them available on Storm&#39;s classpath. In Storm 1.1.0 the <code>storm jar</code> command now includes options to upload additional dependency jars during topology submission. The <code>--jars</code> command line option allows users to specify local jar files to upload. Alternatively, the <code>storm jar</code> command offers the <code>--artifacts</code> option for specifying additional jar file dependencies by their Maven coordinates. Finally, for Maven artifacts outside the Maven Central, the <code>--artifactRepository</code> option allows users to specify additional repositories for dependency resolution.</p>
-
-<p>More informaton about available options of the <code>storm jar</code> command can be found by runnng the <code>storm help jar</code> command.</p>
-
-<h2 id="resource-aware-scheduler-ras-improvements">Resource Aware Scheduler (RAS) Improvements</h2>
-
-<p>The Resource Aware Scheduler introduced in Storm 1.0 added a scheduler implementation that takes into account both the memory (on-heap and off-heap) and CPU resources available in a cluster. In Storm 1.1.0 the RAS algorithm has been overhauled to dramatically improve cluster resource utilization and introduces rack awareness into the scheduling strategy.</p>
-
-<p>More information on the new RAS capabilities can be found in the <a href="/releases/1.1.0/Resource_Aware_Scheduler_overview.html">RAS documentation</a> and the <a href="https://issues.apache.org/jira/browse/STORM-1766">JIRA ticket</a> introducing the new rack awareness algorithm.</p>
-
-<h2 id="important-changes-in-the-binary-distribution">Important Changes in the Binary Distribution</h2>
-
-<p>In order to minimize the file size of the binary distribution, external component (i.e. &quot;connector&quot;) binaries and compiled examples are no longer included. Examples are included in source form only, but can easily compiled with the Maven <code>mvn install</code> command.</p>
-
-<h3 id="external-components-moved-to-maven-central">External Components Moved to Maven Central</h3>
-
-<p>Most external components are now hosted exclusively in Maven Central. External component directories will contain a README.md file, but no jar files. We encourage users to leverage a build system with Maven style dependency resolution (Maven, Gradle, etc.) to build topology jars and avoid building topology jars manually.</p>
-
-<p>Maven coordinates for these components can be determined as follows:</p>
-
-<p>Group ID: org.apache.storm
-Artifact ID: <a href="e.g." title="storm-kafka-client&quot;, &quot;storm-hdfs">component directory name</a>
-Version: 1.1.0</p>
-
-<p>For users who cannot use Maven for building, external component jar files can be downloaded from Maven Central with the following URL pattern:</p>
-<div class="highlight"><pre><code class="language-" data-lang="">http://repo1.maven.org/maven2/org/apache/storm/${artifactID}/${version}/${artifactId}-${version}.jar
-</code></pre></div>
-<p>For example, to download the storm-kafka-client jar file the URL would be:</p>
-<div class="highlight"><pre><code class="language-" data-lang="">http://repo1.maven.org/maven2/org/apache/storm/storm-kafka-client/1.1.0/storm-kafka-client-1.1.0.jar
-</code></pre></div>
-<h2 id="thanks">Thanks</h2>
