+/* ================================================================ */
+
+/*
+ * NOTE 1:
+ * -------
+ *
+ * All checks done in this file are intentionally placed in a public
+ * header file which is pulled by curl/curl.h when an application is
+ * being built using an already built libcurl library. Additionally
+ * this file is also included and used when building the library.
+ *
+ * If compilation fails on this file it is certainly sure that the
+ * problem is elsewhere. It could be a problem in the curlbuild.h
+ * header file, or simply that you are using different compilation
+ * settings than those used to build the library.
+ *
+ * Nothing in this file is intended to be modified or adjusted by the
+ * curl library user nor by the curl library builder.
+ *
+ * Do not deactivate any check, these are done to make sure that the
+ * library is properly built and used.
+ *
+ * You can find further help on the libcurl development mailing list:
+ * http://cool.haxx.se/mailman/listinfo/curl-library/
+ *
+ * NOTE 2
+ * ------
+ *
+ * Some of the following compile time checks are based on the fact
+ * that the dimension of a constant array can not be a negative one.
+ * In this way if the compile time verification fails, the compilation
+ * will fail issuing an error. The error description wording is compiler
+ * dependent but it will be quite similar to one of the following:
+ *
+ *   "negative subscript or subscript is too large"
+ *   "array must have at least one element"
+ *   "-1 is an illegal array size"
+ *   "size of array is negative"
+ *
+ * If you are building an application which tries to use an already
+ * built libcurl library and you are getting this kind of errors on
+ * this file, it is a clear indication that there is a mismatch between
+ * how the library was built and how you are trying to use it for your
+ * application. Your already compiled or binary library provider is the
+ * only one who can give you the details you need to properly use it.

-```cmd

 ## 创建超级表
 一个物联网系统，往往存在多种类型的设备，比如对于电网，存在智能电表、变压器、母线、开关等等。为便于多表之间的聚合，使用TDengine, 需要对每个类型的数据采集点创建一超级表。以表一中的智能电表为例，可以使用如下的SQL命令创建超级表：
-```cmd
+```mysql
 CREATE TABLE meters (ts timestamp, current float, voltage int, phase float) TAGS (location binary(64), groupdId int);
 ```
 与创建普通表一样，创建表时，需要提供表名（示例中为meters），表结构Schema，即数据列的定义。第一列必须为时间戳（示例中为ts)，其他列为采集的物理量（示例中为current, voltage, phase)，数据类型可以为整型、浮点型、字符串等。除此之外，还需要提供标签的schema (示例中为location, groupId)，标签的数据类型可以为整型、浮点型、字符串等。采集点的静态属性往往可以作为标签，比如采集点的地理位置、设备型号、设备组ID、管理员ID等等。标签的schema可以事后增加、删除、修改。具体定义以及细节请见 <a href="https://www.taosdata.com/cn/documentation20/taos-sql/">TAOS SQL </a>一节。

 TDengine支持多列模型，只要物理量是一个数据采集点同时采集的（时间戳一致），这些量就可以作为不同列放在一张超级表里。但还有一种极限的设计，单列模型，每个采集的物理量都单独建表，因此每种类型的物理量都单独建立一超级表。比如电流、电压、相位，就建三张超级表。
 
 TDengine建议尽可能采用多列模型，因为插入效率以及存储效率更高。但对于有些场景，一个采集点的采集量的种类经常变化，这个时候，如果采用多列模型，就需要频繁修改超级表的结构定义，让应用变的复杂，这个时候，采用单列模型会显得简单。

 如果副本数为偶数，当一个vnode group里一半vnode不工作时，是无法从中选出master的。同理，一半mnode不工作时，是无法选出mnode的master的，因为存在“split brain”问题。为解决这个问题，TDengine引入了arbitrator的概念。Arbitrator模拟一个vnode或mnode在工作，但只简单的负责网络连接，不处理任何数据插入或访问。只要包含arbitrator在内，超过半数的vnode或mnode工作，那么该vnode group或mnode组就可以正常的提供数据插入或查询服务。比如对于副本数为2的情形，如果一个节点A离线，但另外一个节点B正常，而且能连接到arbitrator, 那么节点B就能正常工作。
 
 TDengine提供一个执行程序tarbitrator, 找任何一台Linux服务器运行它即可。请点击[安装包下载](https://www.taosdata.com/cn/all-downloads/)，在TDengine Arbitrator Linux一节中，选择适合的版本下载并安装。该程序对系统资源几乎没有要求，只需要保证有网络连接即可。该应用的命令行参数`-p`可以指定其对外服务的端口号，缺省是6042。配置每个taosd实例时，可以在配置文件taos.cfg里将参数arbitrator设置为arbitrator的End Point。如果该参数配置了，当副本数为偶数数，系统将自动连接配置的arbitrator。如果副本数为奇数，即使配置了arbitrator, 系统也不会去建立连接。
