在物联网应用中，常会采集比较多的数据项，用于实现智能控制、业务分析、设备监控等。由于应用逻辑的版本升级，或者设备自身的硬件调整等原因，数据采集项就有可能比较频繁地出现变动。为了在这种情况下方便地完成数据记录工作，TDengine 从 2.2.0.0 版本开始，提供 Schemaless 写入方式，可以免于预先创建超级表/数据子表，而是随着数据写入，自动创建与数据对应的存储结构。并且在必要时，Schemaless 将自动增加必要的数据列，保证用户写入的数据可以被正确存储。目前，TDengine 的 C/C++ Connector 提供支持 Schemaless 的操作接口，详情请参见 [Schemaless 方式写入接口](https://www.taosdata.com/cn/documentation/connector#schemaless) 章节。这里对 Schemaless 的数据表达格式进行描述。
### Schemaless 数据行协议
Schemaless 采用一个字符串来表达最终存储的一个数据行（可以向 Schemaless 写入 API 中一次传入多个字符串来实现多个数据行的批量写入），其格式约定如下：
```json
measurement,tag_set field_set timestamp
```
其中，
* measurement 将作为数据表名。它与 tag_set 之间使用一个英文逗号来分隔。
* tag_set 将作为标签数据，其格式形如 `<tag_key>=<tag_value>,<tag_key>=<tag_value>`，也即可以使用英文逗号来分隔多个标签数据。它与 field_set 之间使用一个半角空格来分隔。
* field_set 将作为普通列数据，其格式形如 `<field_key>=<field_value>,<field_key>=<field_value>`，同样是使用英文逗号来分隔多个普通列的数据。它与 timestamp 之间使用一个半角空格来分隔。
* timestamp 即本行数据对应的主键时间戳。
在 Schemaless 的数据行协议中，tag_set、field_set 中的每个数据项都需要对自身的数据类型进行描述。具体来说：
* 如果两边有英文双引号，表示 BIANRY(32) 类型。例如 `"abc"`。
* 如果两边有英文双引号而且带有 L 前缀，表示 NCHAR(32) 类型。例如 `L"报错信息"`。
* 对空格、等号（=）、逗号（,）、双引号（"），前面需要使用反斜杠（\）进行转义。（都指的是英文半角符号）
* 数值类型将通过后缀来区分数据类型：
- 没有后缀，为 FLOAT 类型；
- 后缀为 f32，为 FLOAT 类型；
- 后缀为 f64，为 DOUBLE 类型；
- 后缀为 i8，表示为 TINYINT (INT8) 类型；
- 后缀为 i16，表示为 SMALLINT (INT16) 类型；
- 后缀为 i32，表示为 INT (INT32) 类型；
- 后缀为 i64，表示为 BIGINT (INT64) 类型；
- 后缀为 b，表示为 BOOL 类型。
* t, T, true, True, TRUE, f, F, false, False 将直接作为 BOOL 型来处理。
timestamp 位置的时间戳通过后缀来声明时间精度，具体如下：
* 不带任何后缀的长整数会被当作微秒来处理；
* 当后缀为 s 时，表示秒时间戳；
* 当后缀为 ms 时，表示毫秒时间戳；
* 当后缀为 us 时，表示微秒时间戳；
* 当后缀为 ns 时，表示纳秒时间戳；
* 当时间戳为 0 时，表示采用客户端的当前时间（因此，同一批提交的数据中，时间戳 0 会被解释为同一个时间点，于是就有可能导致时间戳重复）。
例如，如下 Schemaless 数据行表示：向名为 st 的超级表下的 t1 标签为 3（BIGINT 类型）、t2 标签为 4（DOUBLE 类型）、t3 标签为 "t3"（BINARY 类型）的数据子表，写入 c1 列为 3（BIGINT 类型）、c2 列为 false（BOOL 类型）、c3 列为 "passit"（NCHAR 类型）、c4 列为 4（DOUBLE 类型）、主键时间戳为 1626006833639000000（纳秒精度）的一行数据。
```json
st,t1=3i64,t2=4f64,t3="t3" c1=3i64,c3=L"passit",c2=false,c4=4f64 1626006833639000000ns
```
### Schemaless 的处理逻辑
Schemaless 按照如下原则来处理行数据：
1. 当 tag_set 中有 ID 字段时，该字段的值将作为数据子表的表名。
2. 没有 ID 字段时，将使用 `measurement + tag_value1 + tag_value2 + ...` 的 md5 值来作为子表名。
3. 如果指定的超级表名不存在，则 Schemaless 会创建这个超级表。
4. 如果指定的数据子表不存在，则 Schemaless 会使用 tag values 创建这个数据子表。
5. 如果数据行中指定的标签列或普通列不存在，则 Schemaless 会在超级表中增加对应的标签列或普通列（只增不减）。
6. 如果超级表中存在一些标签列或普通列未在一个数据行中被指定取值，那么这些列的值在这一行中会被置为 NULL。
7. 对 BINARY 或 NCHAR 列，如果数据行中所提供值的长度超出了列类型的限制，那么 Schemaless 会增加该列允许存储的字符长度上限（只增不减），以保证数据的完整保存。
8. 如果指定的数据子表已经存在，而且本次指定的标签列取值跟已保存的值不一样，那么最新的数据行中的值会覆盖旧的标签列取值。
9. 整个处理过程中遇到的错误会中断写入过程，并返回错误代码。
**注意：**Schemaless 所有的处理逻辑，仍会遵循 TDengine 对数据结构的底层限制，例如每行数据的总长度不能超过 16k 字节。这方面的具体限制约束请参见 [TAOS SQL 边界限制](https://www.taosdata.com/cn/documentation/taos-sql#limitation) 章节。
关于 Schemaless 的字符串编码处理、时区设置等，均会沿用 TAOSC 客户端的设置。

* taos：调用 taos_connect 返回的数据库连接。
* lines：由 char 字符串指针组成的数组，指向本次想要写入数据库的多行数据。
* numLines：lines 数据的总行数。
返回值为 0 表示写入成功，非零值表示出错。具体错误代码请参见 [taoserror.h](https://github.com/taosdata/TDengine/blob/develop/src/inc/taoserror.h) 文件。
说明：
1. 此接口是一个同步阻塞式接口，使用时机与 `taos_query()` 一致。
2. 在调用此接口之前，必须先调用 `taos_select_db()` 来确定目前是在向哪个 DB 来写入。

## 浮点数有损压缩
在车联网等物联网智能应用场景中，经常会采集和存储海量的浮点数类型数据，如果能更高效地对此类数据进行压缩，那么不但能够节省数据存储的硬件资源，也能够因降低磁盘 I/O 数据量而提升系统性能表现。
从 2.1.6.0 版本开始，TDengine 提供一种名为 TSZ 的新型数据压缩算法，无论设置为有损压缩还是无损压缩，都能够显著提升浮点数类型数据的压缩率表现。目前该功能以可选模块的方式进行发布，可以通过添加特定的编译参数来启用该功能（也即常规安装包中暂未包含该功能）。
**需要注意的是，该功能一旦启用，效果是全局的，也即会对系统中所有的 FLOAT、DOUBLE 类型的数据生效。同时，在启用了浮点数有损压缩功能后写入的数据，也无法被未启用该功能的版本载入，并有可能因此而导致数据库服务报错退出。**
### 创建支持 TSZ 压缩算法的 TDengine 版本
TSZ 模块保存在单独的代码仓库 https://github.com/taosdata/TSZ 中。可以通过以下步骤创建包含此模块的 TDengine 版本：
1. TDengine 中的插件目前只支持通过 SSH 的方式拉取和编译，所以需要自己先配置好通过 SSH 拉取 GitHub 代码的环境。
2. `git clone git@github.com:taosdata/TDengine -b your_branchname --recurse-submodules` 通过 `--recurse-submodules` 使依赖模块的源代码可以被一并下载。
3. `mkdir debug && cd debug` 进入单独的编译目录。
4. `cmake .. -DTSZ_ENABLED=true` 其中参数 `-DTSZ_ENABLED=true` 表示在编译过程中加入对 TSZ 插件功能的支持。如果成功激活对 TSZ 模块的编译，那么 CMAKE 过程中也会显示 `build with TSZ enabled` 字样。
5. 编译成功后，包含 TSZ 浮点压缩功能的插件便已经编译进了 TDengine 中了，可以通过调整 taos.cfg 中的配置参数来使用此功能了。
### 通过配置文件来启用 TSZ 压缩算法
如果要启用 TSZ 压缩算法，除了在 TDengine 的编译过程需要声明启用 TSZ 模块之外，还需要在 taos.cfg 配置文件中对以下参数进行设置：
* lossyColumns：配置要进行有损压缩的浮点数数据类型。参数值类型为字符串，含义为：空 - 关闭有损压缩；float - 只对 FLOAT 类型进行有损压缩；double - 只对 DOUBLE 类型进行有损压缩；float|double：对 FLOAT 和 DOUBLE 类型都进行有损压缩。默认值是“空”，也即关闭有损压缩。
* fPrecision：设置 float 类型浮点数压缩精度，小于此值的浮点数尾数部分将被截断。参数值类型为 FLOAT，最小值为 0.0，最大值为 100,000.0。缺省值为 0.00000001（1E-8）。
* dPrecision：设置 double 类型浮点数压缩精度，小于此值的浮点数尾数部分将被截断。参数值类型为 DOUBLE，最小值为 0.0，最大值为 100,000.0。缺省值为 0.0000000000000001（1E-16）。
* maxRange：表示数据的最大浮动范围。一般无需调整，在数据具有特定特征时可以配合 range 参数来实现极高的数据压缩率。默认值为 500。
* range：表示数据大体浮动范围。一般无需调整，在数据具有特定特征时可以配合 maxRange 参数来实现极高的数据压缩率。默认值为 100。
**注意：**对 cfg 配置文件中参数值的任何调整，都需要重新启动 taosd 才能生效。并且以上选项为全局配置选项，配置后对所有数据库中所有表的 FLOAT 及 DOUBLE 类型的字段生效。

### JOIN 子句
从 2.2.0.0 版本开始，TDengine 对内连接（INNER JOIN）中的自然连接（Natural join）操作实现了完整的支持。也即支持“普通表与普通表之间”、“超级表与超级表之间”、“子查询与子查询之间”进行自然连接。自然连接与内连接的主要区别是，自然连接要求参与连接的字段在不同的表/超级表中必须是同名字段。也即，TDengine 在连接关系的表达中，要求必须使用同名数据列/标签列的相等关系。
在普通表与普通表之间的 JOIN 操作中，只能使用主键时间戳之间的相等关系。例如：
```sql
SELECT *
FROM temp_tb_1 t1, pressure_tb_1 t2
WHERE t1.ts = t2.ts
```
在超级表与超级表之间的 JOIN 操作中，除了主键时间戳一致的条件外，还要求引入能实现一一对应的标签列的相等关系。例如：
```sql
SELECT *
FROM temp_stable t1, temp_stable t2
WHERE t1.ts = t2.ts AND t1.deviceid = t2.deviceid AND t1.status=0;
```
类似地，也可以对多个子查询的查询结果进行 JOIN 操作。
注意，JOIN 操作存在如下限制要求：
1. 参与一条语句中 JOIN 操作的表/超级表最多可以有 10 个。
2. 在包含 JOIN 操作的查询语句中不支持 FILL。
3. 暂不支持参与 JOIN 操作的表之间聚合后的四则运算。
4. 不支持只对其中一部分表做 GROUP BY。
5. JOIN 查询的不同表的过滤条件之间不能为 OR。
