| 一个时序是由4个序列组成，分别是 device, measurement, time, value。</p> <ul><li><p><strong>measurement</strong>: 时间序列描述的是一个物理或者形式的测量(measurement)，比如：城市的温度，一些商品的销售数量或者是火车在不同时间的速度。 |
| 传统的传感器(如温度计)也采用单次测量(measurement)并产生时间序列，我们将在下面交替使用测量(measurement)和传感器。</p></li> <li><p><strong>device</strong>: 一个设备指的是一个正在进行多次测量(产生多个时间序列)的实体，例如， |
| 一列正在运行的火车监控它的速度、油表、它已经运行的英里数，当前的乘客每个都被传送到一个时间序列。</p></li></ul> <p><strong>单行数据</strong>: 在许多工业应用程序中，一个设备通常包含多个传感器，这些传感器可能同时具有多个值，这称为一行数据。</p> <p>在形式上，一行数据包含一个<code>device_id</code>，它是一个时间戳，表示从 1970年1月1日 00:00:00 开始的毫秒数, |
| 以及由<code>measurement_id</code>和相应的<code>value</code>组成的几个数据对。一行中的所有数据对都属于这个<code>device_id</code>，并且具有相同的时间戳。 |
| 如果其中一个度量值<code>measurements</code>在某个时间戳<code>timestamp</code>没有值<code>value</code>，将使用一个空格表示(实际上 TsFile 并不存储 null 值)。 |
| 其格式如下：</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>device_id, timestamp, <measurement_id, value>... |
| </code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br></div></div><p>示例数据如下所示。在本例中，两个度量值(measurement)的数据类型分别是<code>INT32</code>和<code>FLOAT</code>。</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>device_1, 1490860659000, m1, 10, m2, 12.12 |
