You can connect to data sources and perform interactive operations with SQL, Scala, etc. The operations can be saved as documents, just like Jupyter. Zeppelin has already supported many data sources, including Spark, ElasticSearch, Cassandra, and InfluxDB. Now, we have enabled Zeppelin to operate IoTDB via SQL.</p><figure><img src="https://alioss.timecho.com/docs/img/github/102752947-520a3e80-43a5-11eb-8fb1-8fac471c8c7e.png" alt="iotdb-note-snapshot" tabindex="0" loading="lazy"><figcaption>iotdb-note-snapshot</figcaption></figure><h3 id="zeppelin-iotdb-interpreter" tabindex="-1"><a class="header-anchor" href="#zeppelin-iotdb-interpreter" aria-hidden="true">#</a> Zeppelin-IoTDB Interpreter</h3><h4 id="system-requirements" tabindex="-1"><a class="header-anchor" href="#system-requirements" aria-hidden="true">#</a> System Requirements</h4><table><thead><tr><th style="text-align:center;">IoTDB Version</th><th style="text-align:center;">Java Version</th><th style="text-align:center;">Zeppelin Version</th></tr></thead><tbody><tr><td style="text-align:center;">&gt;=<code>0.12.0</code></td><td style="text-align:center;">&gt;=<code>1.8.0_271</code></td><td style="text-align:center;"><code>&gt;=0.9.0</code></td></tr></tbody></table><p>Install IoTDB: Reference to <a href="/UserGuide/V1.1.x/QuickStart/QuickStart.html" class="">IoTDB Quick Start</a>.
