为支持各种不同类型平台的开发，TDengine 提供符合 REST 设计标准的 API，即 RESTful API。为最大程度降低学习成本，不同于其他数据库 RESTful API 的设计方法，TDengine 直接通过 HTTP POST 请求 BODY 中包含的 SQL 语句来操作数据库，仅需要一个 URL。RESTful 连接器的使用参见[视频教程](https://www.taosdata.com/blog/2020/11/11/1965.html)。
注意：与标准连接器的一个区别是，RESTful 接口是无状态的，因此 `USE db_name` 指令没有效果，所有对表名、超级表名的引用都需要指定数据库名前缀。

### 安装
RESTful接口不依赖于任何TDengine的库，因此客户端不需要安装任何TDengine的库，只要客户端的开发语言支持HTTP协议即可。

# Quickly experience TDengine through Docker
While it is not recommended to deploy TDengine services via Docker in a production environment, Docker tools do a good job of shielding the environmental differences in the underlying operating system and are well suited for use in development testing or first-time experience with the toolset for installing and running TDengine. In particular, Docker makes it relatively easy to try TDengine on Mac OSX and Windows systems without having to install a virtual machine or rent an additional Linux server. In addition, starting from version 2.0.14.0, TDengine provides images that support both X86-64, X86, arm64, and arm32 platforms, so non-mainstream computers that can run docker, such as NAS, Raspberry Pi, and embedded development boards, can also easily experience TDengine based on this document.
The following article explains how to quickly build a single-node TDengine runtime environment via Docker to support development and testing through a Step by Step style introduction.
## Docker download
The Docker tools themselves can be downloaded from [Docker official site](https://docs.docker.com/get-docker/).
After installation, you can check the Docker version in the command line terminal. If the version number is output properly, the Docker environment has been installed successfully.
```bash
$ docker -v
Docker version 20.10.3, build 48d30b5
```
## Running TDengine in a Docker container
1, Use the command to pull the TDengine image and make it run in the background.
```bash
$ docker run -d --name tdengine tdengine/tdengine
7760c955f225d72e9c1ec5a4cef66149a7b94dae7598b11eb392138877e7d292
```
- **docker run**: Running a container via Docker
- **--name tdengine**: Set the container name, we can see the corresponding container by the container name
- **-d**: Keeping containers running in the background
- **tdengine/tdengine**: Pulled from the official TDengine published application image
- **7760c955f225d72e9c1ec5a4cef66149a7b94dae7598b11eb392138877e7d292**: The long character returned is the container ID, and we can also view the corresponding container by its container ID
2, Verify that the container is running correctly.
```bash
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS ···
c452519b0f9b tdengine/tdengine "taosd" 14 minutes ago Up 14 minutes ···
```
- **docker ps**: Lists information about all containers that are in running state.
- **CONTAINER ID**: Container ID.
- **IMAGE**: The mirror used.
- **COMMAND**: The command to run when starting the container.
- **CREATED**: The time when the container was created.
- **STATUS**: The container status. Up means running.
3, Go inside the Docker container and use TDengine.
```bash
$ docker exec -it tdengine /bin/bash
root@c452519b0f9b:~/TDengine-server-2.0.20.13#
```
- **docker exec**: Enter the container via the docker exec command; if you exit, the container will not stop.
- **-i**: Enter the interactive mode.
- **-t**: Specify a terminal.
- **c452519b0f9b**: The container ID, which needs to be modified according to the value returned by the docker ps command.
- **/bin/bash**: Load the container and run bash to interact with it.
4, After entering the container, execute the taos shell client program.
```bash
$ root@c452519b0f9b:~/TDengine-server-2.0.20.13# taos
Welcome to the TDengine shell from Linux, Client Version:2.0.20.13
Copyright (c) 2020 by TAOS Data, Inc. All rights reserved.
taos>
```
The TDengine terminal successfully connects to the server and prints out a welcome message and version information. If it fails, an error message is printed.
In the TDengine terminal, you can create/delete databases, tables, super tables, etc., and perform insert and query operations via SQL commands. For details, you can refer to [TAOS SQL guide](https://www.taosdata.com/en/documentation/taos-sql).
## Learn more about TDengine with taosdemo
1, Following the above steps, exit the TDengine terminal program first.
```bash
$ taos> q

```
2, Execute taosdemo from the command line interface.
```bash

```
After enter, this command will automatically create a super table meters under the database test, there are 10,000 tables under this super table, the table name is "d0" to "d9999", each table has 10,000 records, each record has four fields (ts, current, voltage, phase), the time stamp is from "2017-07-14 10:40:00 000" to "2017-07-14 10:40:09 999", each table has a tag location and groupId, groupId is set from 1 to 10 and location is set to "beijing" or "shanghai".
It takes about a few minutes to execute this command and ends up inserting a total of 100 million records.

## Stop the TDengine service that is running in Docker
```bash
$ docker stop tdengine
tdengine
```
- **docker stop**: Stop the specified running docker image with docker stop.
- **tdengine**: The name of the container.
## TDengine connected in Docker during programming development
There are two ideas for connecting from outside of Docker to use TDengine services running inside a Docker container:
1, By port mapping (-p), the open network port inside the container is mapped to the specified port of the host. By mounting the local directory (-v), you can synchronize the data inside the host and the container to prevent data loss after the container is deleted.
```bash
$ docker run -d -v /etc/taos:/etc/taos -P 6041:6041 tdengine/tdengine
526aa188da767ae94b244226a2b2eec2b5f17dd8eff592893d9ec0cd0f3a1ccd
$ curl -u root:taosdata -d 'show databases' 127.0.0.1:6041/rest/sql
{"status":"succ","head":["name","created_time","ntables","vgroups","replica","quorum","days","keep0,keep1,keep(D)","cache(MB)","blocks","minrows","maxrows","wallevel","fsync","comp","cachelast","precision","update","status"],"column_meta":[["name",8,32],["created_time",9,8],["ntables",4,4],["vgroups",4,4],["replica",3,2],["quorum",3,2],["days",3,2],["keep0,keep1,keep(D)",8,24],["cache(MB)",4,4],["blocks",4,4],["minrows",4,4],["maxrows",4,4],["wallevel",2,1],["fsync",4,4],["comp",2,1],["cachelast",2,1],["precision",8,3],["update",2,1],["status",8,10]],"data":[["test","2021-08-18 06:01:11.021",10000,4,1,1,10,"3650,3650,3650",16,6,100,4096,1,3000,2,0,"ms",0,"ready"],["log","2021-08-18 05:51:51.065",4,1,1,1,10,"30,30,30",1,3,100,4096,1,3000,2,0,"us",0,"ready"]],"rows":2}
```
- The first command starts a docker container with TDengine running and maps the 6041 port of the container to port 6041 of the host.
- The second command, accessing TDengine through the RESTful interface, connects to port 6041 on the local machine, so the connection is successful.
Note: In this example, for convenience reasons, only port 6041 is mapped, which is required for RESTful. If you wish to connect to the TDengine service in a non-RESTful manner, you will need to map a total of 11 ports starting at 6030. In the example, mounting the local directory also only deals with the /etc/taos directory where the configuration files are located, but not the data storage directory.
2, Go directly to the docker container to do development via the exec command. That is, put the program code in the same Docker container where the TDengine server is located and connect to the TDengine service local to the container.
```bash
$ docker exec -it tdengine /bin/bash
```

For the time being, it is not recommended to use Docker to deploy the client or server side of TDengine in production environments, but it is convenient to use Docker to deploy in development environments or when trying it for the first time. In particular, with Docker, it is easy to try TDengine in Mac OS X and Windows environments.

### STable: A Collection of Data Points in the Same Type
The method of one table for each point will bring a greatly increasing number of tables, which is difficult to manage. Moreover, applications often need to take aggregation operations between collection points, thus aggregation operations will become complicated. To support aggregation over multiple tables efficiently, the [STable(Super Table)](https://www.taosdata.com/en/documentation/super-table) concept is introduced by TDengine.
The method of one table for each point will bring a greatly increasing number of tables, which is difficult to manage. Moreover, applications often need to take aggregation operations between collection points, thus aggregation operations will become complicated. To support aggregation over multiple tables efficiently, the STable (Super Table) concept is introduced by TDengine.
STable is an abstract collection for a type of data point. A STable contains a set of points (tables) that have the same schema or data structure, but with different static attributes (tags). To describe a STable (a combination of data collection points of a specific type), in addition to defining the table structure of the collected metrics, it is also necessary to define the schema of its tag. The data type of tags can be int, float, string, and there can be multiple tags, which can be added, deleted, or modified afterward. If the whole system has N different types of data collection points, N STables need to be established.
