<div id="toc"></div> <h2>Overview</h2> <p><a href="https://ignite.apache.org/">Apache Ignite</a> In-Memory Data Fabric is a high-performance, integrated and distributed in-memory platform for computing and transacting on large-scale data sets in real-time, orders of magnitude faster than possible with traditional disk-based or flash technologies.</p> <p><img src="/docs/0.10.1/assets/themes/zeppelin/img/docs-img/ignite-logo.png" alt="Apache Ignite"></p> <p>You can use Zeppelin to retrieve distributed data from cache using Ignite SQL interpreter. Moreover, Ignite interpreter allows you to execute any Scala code in cases when SQL doesn't fit to your requirements. For example, you can populate data into your caches or execute distributed computations.</p> <h2>Installing and Running Ignite example</h2> <p>In order to use Ignite interpreters, you may install Apache Ignite in some simple steps:</p> <ol> <li>Ignite provides examples only with source or binary release. Download Ignite <a href="https://ignite.apache.org/download.html#sources">source release</a> or <a href="https://ignite.apache.org/download.html#binaries">binary release</a> whatever you want. But you must download Ignite as the same version of Zeppelin's. If it is not, you can't use scala code on Zeppelin. The supported Ignite version is specified in <a href="https://zeppelin.apache.org/supported_interpreters.html#ignite">Supported Interpreter table</a> for each Zeppelin release. If you're using Zeppelin master branch, please see <code>ignite.version</code> in <code>path/to/your-Zeppelin/ignite/pom.xml</code>.</li> <li>Examples are shipped as a separate Maven project, so to start running you simply need to import provided <code><dest_dir>/apache-ignite-fabric-{version}-bin/examples/pom.xml</code> file into your favourite IDE, such as Eclipse.</li> </ol> <ul> <li>In case of Eclipse, Eclipse -> File -> Import -> Existing Maven Projects</li> <li>Set examples directory path to Eclipse and select the pom.xml.</li> <li>Then start <code>org.apache.ignite.examples.ExampleNodeStartup</code> (or whatever you want) to run at least one or more ignite node. When you run example code, you may notice that the number of node is increase one by one.</li> </ul> <blockquote> <p><strong>Tip. If you want to run Ignite examples on the cli not IDE, you can export executable Jar file from IDE. Then run it by using below command.</strong></p> </blockquote> <div class="highlight"><pre><code class="bash language-bash" data-lang="bash">nohup java -jar </path/to/your Jar file name> </code></pre></div> <h2>Configuring Ignite Interpreter</h2> <p>At the "Interpreters" menu, you may edit Ignite interpreter or create new one. Zeppelin provides these properties for Ignite.</p> <table class="table-configuration"> <tr> <th>Property Name</th> <th>value</th> <th>Description</th> </tr> <tr> <td>ignite.addresses</td> <td>127.0.0.1:47500..47509</td> <td>Coma separated list of Ignite cluster hosts. See <a href="https://apacheignite.readme.io/docs/cluster-config">Ignite Cluster Configuration</a> section for more details.</td> </tr> <tr> <td>ignite.clientMode</td> <td>true</td> <td>You can connect to the Ignite cluster as client or server node. See <a href="https://apacheignite.readme.io/docs/clients-vs-servers">Ignite Clients vs. Servers</a> section for details. Use true or false values in order to connect in client or server mode respectively.</td> </tr> <tr> <td>ignite.config.url</td> <td></td> <td>Configuration URL. Overrides all other settings.</td> </tr> <tr> <td>ignite.jdbc.url</td> <td>jdbc:ignite:cfg://default-ignite-jdbc.xml</td> <td>Ignite JDBC connection URL.</td> </tr> <tr> <td>ignite.peerClassLoadingEnabled</td> <td>true</td> <td>Enables peer-class-loading. See <a href="https://apacheignite.readme.io/docs/zero-deployment">Zero Deployment</a> section for details. Use true or false values in order to enable or disable P2P class loading respectively.</td> </tr> </table> <p><img src="/docs/0.10.1/assets/themes/zeppelin/img/docs-img/ignite-interpreter-setting.png" alt="Configuration of Ignite Interpreter"></p> <h2>How to use</h2> <p>After configuring Ignite interpreter, create your own notebook. Then you can bind interpreters like below image.</p> <p><img src="/docs/0.10.1/assets/themes/zeppelin/img/docs-img/ignite-interpreter-binding.png" alt="Binding Interpreters"></p> <p>For more interpreter binding information see <a href="../usage/interpreter/overview.html#what-is-interpreter-setting">here</a>.</p> <h3>Ignite SQL interpreter</h3> <p>In order to execute SQL query, use <code>%ignite.ignitesql</code> prefix. <br> Supposing you are running <code>org.apache.ignite.examples.streaming.wordcount.StreamWords</code>, then you can use "words" cache( Of course you have to specify this cache name to the Ignite interpreter setting section <code>ignite.jdbc.url</code> of Zeppelin ). For example, you can select top 10 words in the words cache using the following query</p> <div class="highlight"><pre><code class="sql language-sql" data-lang="sql"><span class="o">%</span><span class="n">ignite</span><span class="p">.</span><span class="n">ignitesql</span> <span class="k">select</span> <span class="n">_val</span><span class="p">,</span> <span class="k">count</span><span class="p">(</span><span class="n">_val</span><span class="p">)</span> <span class="k">as</span> <span class="n">cnt</span> <span class="k">from</span> <span class="n">String</span> <span class="k">group</span> <span class="k">by</span> <span class="n">_val</span> <span class="k">order</span> <span class="k">by</span> <span class="n">cnt</span> <span class="k">desc</span> <span class="k">limit</span> <span class="mi">10</span> </code></pre></div> <p><img src="/docs/0.10.1/assets/themes/zeppelin/img/docs-img/ignite-sql-example.png" alt="IgniteSql on Zeppelin"></p> <p>As long as your Ignite version and Zeppelin Ignite version is same, you can also use scala code.
