 The primary key, i.e. timestamp, is used to determine which session window a row belongs to. As shown in the figure below, if the limit of time interval for the session window is specified as 12 seconds, then the 6 rows in the figure constitutes 2 time windows, [2019-04-28 14:22:10，2019-04-28 14:22:30] and [2019-04-28 14:23:10，2019-04-28 14:23:30] because the time difference between 2019-04-28 14:22:30 and 2019-04-28 14:23:10 is 40 seconds, which exceeds the time interval limit of 12 seconds.

+TDengine 提供了兼容 InfluxDB (v1) 和 OpenTSDB 行协议的 Schemaless API。支持 InfluxDB（v1) 或 OpenTSDB 行协议写入数据的第三方软件无需修改代码，只要修改配置的 EndPoint URL 就可以直接把数据写入 TDengine 数据库。
+
+### 兼容 InfluxDB 行协议写入的方法
+
+您可以配置任何支持使用 InfluxDB（v1） 行协议的应用访问地址 `http://<fqdn>:6041/<APIEndPoint>` 来写入 InfluxDB 兼容格式的数据到 TDengine。EndPoint 如下：
+```text
+/influxdb/v1/write?<param1=value1>?<param2=value2>...
+```
+
+支持 InfluxDB 查询参数如下：
+
+- `db` 指定 TDengine 使用的数据库名
+- `precision` TDengine 使用的时间精度
+- `u` TDengine 用户名
+- `p` TDengine 密码
+
+注意： 目前不支持 InfluxDB 的 token 验证方式，仅支持 Basic 验证和查询参数验证。
