class="header-anchor" href="#introduction"><span>Introduction</span></a></h3><p>The Sync Tool is an IoTDB suite tool that periodically uploads persistent tsfiles from the sender disk to the receiver and loads them.</p><p>On the sender side of the sync, the sync module is a separate process, independent of the IoTDB process. It can be started and closed through a separate script (see Sections <code>Usage</code> for details). The frequency cycle of the sync can be set by the user.</p><p>On the receiver side of the sync, the sync module is embedded in the engine of IoTDB and is in the same process with IoTDB. The receiver module listens for a separate port, which can be set by the user (see Section <code>Configuration</code> for details). Before using it, it needs to set up a whitelist at the sync receiver, which is expressed as a network segment. The receiver only accepts the data transferred from the sender located in the whitelist segment, as detailed in Section <code>Configuration</code>.</p><p>The sync tool has a many-to-one sender-receiver mode - that is, one sync receiver can receive data from multiple sync senders simultaneously while one sync sender can only send data to one sync receiver.</p><blockquote><p>Note: Before using the sync tool, the client and server need to be configured separately. The configuration is detailed in Sections Configuration.</p></blockquote><h3 id="application-scenario" tabindex="-1"><a class="header-anchor" href="#application-scenario"><span>Application Scenario</span></a></h3><p>In the case of a factory application, there are usually multiple sub-factories and multiple general(main) factories. Each sub-factory uses an IoTDB instance to collect data, and then synchronize the data to the general factory for backup or analysis. A general factory can receive data from multiple sub-factories and a sub-factory can also synchronize data to multiple general factories. In this scenario, each IoTDB instance manages different devices.<br> ​<br> In the sync module, each sub-factory is a sender, a general factory is a receiver, and senders periodically synchronizes the data to receivers. In the scenario above, the data of one device can only be collected by one sender, so there is no device overlap between the data synchronized by multiple senders. Otherwise, the application scenario of the sync module is not satisfied.</p><p>When there is an abnormal scenario, namely, two or more senders synchronize the data of the same device (whose storage group is set as <a href="http://root.sg" target="_blank" rel="noopener noreferrer">root.sg<span><svg class="external-link-icon" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" focusable="false" x="0px" y="0px" viewBox="0 0 100 100" width="15" height="15"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path><polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg><span class="external-link-icon-sr-only">open in new window</span></span></a>) to the same receiver, the <a href="http://root.sg" target="_blank" rel="noopener noreferrer">root.sg<span><svg class="external-link-icon" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" focusable="false" x="0px" y="0px" viewBox="0 0 100 100" width="15" height="15"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path><polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg><span class="external-link-icon-sr-only">open in new window</span></span></a> data of the sender containing the device data received later by the receiver will be rejected.
