id="tsfile导入导出工具" tabindex="-1"><a class="header-anchor" href="#tsfile导入导出工具" aria-hidden="true">#</a> TsFile导入导出工具</h2><p>TsFile 是在 IoTDB 中使用的时间序列的文件格式，您可以通过CLI等工具直接将存有时间序列的一个或多个 TsFile 文件导入到另外一个正在运行的IoTDB实例中。</p><h3 id="介绍" tabindex="-1"><a class="header-anchor" href="#介绍" aria-hidden="true">#</a> 介绍</h3><p>加载外部 tsfile 文件工具允许用户向正在运行中的 Apache IoTDB 中加载 tsfile 文件。或者您也可以使用脚本的方式将tsfile加载进IoTDB。</p><h3 id="使用sql加载" tabindex="-1"><a class="header-anchor" href="#使用sql加载" aria-hidden="true">#</a> 使用SQL加载</h3><p>用户通过 Cli 工具或 JDBC 向 Apache IoTDB 系统发送指定命令实现文件加载的功能。</p><h4 id="加载-tsfile-文件" tabindex="-1"><a class="header-anchor" href="#加载-tsfile-文件" aria-hidden="true">#</a> 加载 tsfile 文件</h4><p>加载 tsfile 文件的指令为：<code>load '<path/dir>' [sglevel=int][verify=true/false][onSuccess=delete/none]</code></p><p>该指令有两种用法：</p><ol><li>通过指定文件路径(绝对路径)加载单 tsfile 文件。</li></ol><p>第一个参数表示待加载的 tsfile 文件的路径。load 命令有三个可选项，分别是 sglevel，值域为整数，verify，值域为 true/false，onSuccess，值域为delete/none。不同选项之间用空格隔开，选项之间无顺序要求。</p><p>SGLEVEL 选项，当 tsfile 对应的 database 不存在时，用户可以通过 sglevel 参数的值来制定 database 的级别，默认为<code>iotdb-datanode.properties</code>中设置的级别。例如当设置 level 参数为1时表明此 tsfile 中所有时间序列中层级为1的前缀路径是 database，即若存在设备 root.sg.d1.s1，此时 <a href="http://root.sg" target="_blank" rel="noopener noreferrer">root.sg<span><svg class="external-link-icon"

中的所有时间序列进行元数据检查，默认为 true。开启时，若载入的 tsfile 中的时间序列在当前 iotdb 中也存在，则会比较该时间序列的所有 Measurement 的数据类型是否一致，如果出现不一致将会导致载入失败，关闭该选项会跳过检查，载入更快。</p><p>ONSUCCESS选项表示对于成功载入的tsfile的处置方式，默认为delete，即tsfile成功加载后将被删除，如果是none表明tsfile成功加载之后依然被保留在源文件夹。</p><p>若待加载的 tsfile 文件对应的<code>.resource</code>文件存在，会被一并加载至 Apache IoTDB 数据文件的目录和引擎中，否则将通过 tsfile 文件重新生成对应的<code>.resource</code>文件，即加载的 tsfile 文件所对应的<code>.resource</code>文件不是必要的。</p><p>示例：</p><ul><li><code>load
