TDengine是一个高效的存储、查询、分析时序大数据的平台，专为物联网、车联网、工业互联网、运维监测等优化而设计。您可以像使用关系型数据库MySQL一样来使用它，但建议您在使用前仔细阅读一遍下面的文档，特别是 [数据模型](https://www.taosdata.com/cn/documentation/architecture) 与 [数据建模](https://www.taosdata.com/cn/documentation/model)。除本文档之外，欢迎 [下载产品白皮书](https://www.taosdata.com/downloads/TDengine%20White%20Paper.pdf)。

TDengine目前2.0版服务器仅能在Linux系统上安装和运行，后续会支持Windows、macOS等系统。客户端可以在Windows或Linux上安装和运行。任何OS的应用也可以选择RESTful接口连接服务器taosd。CPU支持X64/ARM64/MIPS64/Alpha64，后续会支持ARM32、RISC-V等CPU架构。用户可根据需求选择通过[源码](https://www.taosdata.com/cn/getting-started/#通过源码安装)或者[安装包](https://www.taosdata.com/cn/getting-started/#通过安装包安装)来安装。本快速指南仅适用于通过源码安装。

**注意**：在调用 `taos_consume()` 之后，用户应用应确保尽快调用 `taos_fetch_row()` 或 `taos_fetch_block()` 来处理订阅结果，否则服务端会持续缓存查询结果数据等待客户端读取，极端情况下会导致服务端内存消耗殆尽，影响服务稳定性。

TDengine 支持按时间段等窗口切分方式进行聚合结果查询，比如温度传感器每秒采集一次数据，但需查询每隔 10 分钟的温度平均值。这类聚合适合于降维（down sample）操作，语法如下：

```
- 聚合时间段的长度由关键词INTERVAL指定，最短时间间隔10毫秒（10a），并且支持偏移（偏移必须小于间隔）。聚合查询中，能够同时执行的聚合和选择函数仅限于单个输出的函数：count、avg、sum 、stddev、leastsquares、percentile、min、max、first、last，不能使用具有多行输出结果的函数（例如：top、bottom、diff以及四则运算）。
- WHERE语句可以指定查询的起止时间和其他过滤条件。
- SLIDING语句用于指定聚合时间段的前向增量。
- FILL语句指定某一时间区间数据缺失的情况下的填充模式。填充模式包括以下几种：
1. 不进行填充：NONE(默认填充模式)。
2. VALUE填充：固定值填充，此时需要指定填充的数值。例如：FILL(VALUE, 1.23)。
3. NULL填充：使用NULL填充数据。例如：FILL(NULL)。
4. PREV填充：使用前一个非NULL值填充数据。例如：FILL(PREV)。
5. NEXT填充：使用下一个非NULL值填充数据。例如：FILL(NEXT)。
- 在聚合查询中，function_list 位置允许使用聚合和选择函数，并要求每个函数仅输出单个结果（例如：COUNT、AVG、SUM、STDDEV、LEASTSQUARES、PERCENTILE、MIN、MAX、FIRST、LAST），而不能使用具有多行输出结果的函数（例如：TOP、BOTTOM、DIFF 以及四则运算）。
- 查询过滤、聚合等操作按照每个切分窗口为独立的单位执行。聚合查询目前支持三种窗口的划分方式：
1. 时间窗口：聚合时间段的窗口宽度由关键词 INTERVAL 指定，最短时间间隔 10 毫秒（10a）；并且支持偏移 offset（偏移必须小于间隔），也即时间窗口划分与“UTC 时刻 0”相比的偏移量。SLIDING 语句用于指定聚合时间段的前向增量，也即每次窗口向前滑动的时长。当 SLIDING 与 INTERVAL 取值相等的时候，滑动窗口即为翻转窗口。
2. 状态窗口：使用整数（布尔值）或字符串来标识产生记录时设备的状态量，产生的记录如果具有相同的状态量取值则归属于同一个状态窗口，数值改变后该窗口关闭。状态量所对应的列作为 STAT_WINDOW 语句的参数来指定。
3. 会话窗口：时间戳所在的列由 SESSION 语句的 ts_col 参数指定，会话窗口根据相邻两条记录的时间戳差值来确定是否属于同一个会话——如果时间戳差异在 tol_val 以内，则认为记录仍属于同一个窗口；如果时间变化超过 tol_val，则自动开启下一个窗口。
- WHERE 语句可以指定查询的起止时间和其他过滤条件。
- FILL 语句指定某一窗口区间数据缺失的情况下的填充模式。填充模式包括以下几种：
1. 不进行填充：NONE（默认填充模式）。
2. VALUE 填充：固定值填充，此时需要指定填充的数值。例如：FILL(VALUE, 1.23)。
3. PREV 填充：使用前一个非 NULL 值填充数据。例如：FILL(PREV)。
4. NULL 填充：使用 NULL 填充数据。例如：FILL(NULL)。
5. LINEAR 填充：根据前后距离最近的非 NULL 值做线性插值填充。例如：FILL(LINEAR)。
6. NEXT 填充：使用下一个非 NULL 值填充数据。例如：FILL(NEXT)。
说明：
1. 使用FILL语句的时候可能生成大量的填充输出，务必指定查询的时间区间。针对每次查询，系统可返回不超过1千万条具有插值的结果。
1. 使用 FILL 语句的时候可能生成大量的填充输出，务必指定查询的时间区间。针对每次查询，系统可返回不超过 1 千万条具有插值的结果。
2. 在时间维度聚合中，返回的结果中时间序列严格单调递增。
3. 如果查询对象是超级表，则聚合函数会作用于该超级表下满足值过滤条件的所有表的数据。如果查询中没有使用GROUP BY语句，则返回的结果按照时间序列严格单调递增；如果查询中使用了GROUP BY语句分组，则返回结果中每个GROUP内不按照时间序列严格单调递增。

TDegnine software consists of 3 parts: server, client, and alarm module. At the moment, TDengine server only runs on Linux (Windows, mac OS and more OS supports will come soon), but client can run on either Windows or Linux. TDengine client can be installed and run on Windows or Linux. Applications based-on any OSes can all connect to server taosd via a RESTful interface. About CPU, TDegnine supports X64/ARM64/MIPS64/Alpha64, and ARM32、RISC-V, other more CPU architectures will be supported soon. You can set up and install TDengine server either from the [source code](https://www.taosdata.com/en/getting-started/#Install-from-Source) or the [packages](https://www.taosdata.com/en/getting-started/#Install-from-Package).
