title: Data Model
---
The data model employed by TDengine is similar to that of a relational database. You have to create databases and tables. You must design the data model based on your own business and application requirements. You should design the [STable](/concept/#super-table-stable) (an abbreviation for super table) schema to fit your data. This chapter will explain the big picture without getting into syntactical details.

You should design the [STable](/concept/#super-table-stable) (an abbreviation for super table) schema to fit your data. This chapter will explain the big picture without getting into syntactical details.
Note: before you read this chapter, please make sure you have already read through [Key Concepts](/concept/), since TDengine introduces new concepts like "one table for one [data collection point](/concept/#data-collection-point)" and "[super table](/concept/#super-table-stable)".
## Create Database
The characteristics of time-series data from different data collection points may be different. Characteristics include collection frequency, retention policy and others which determine how you create and configure the database. For e.g. days to keep, number of replicas, data block size, whether data updates are allowed and other configurable parameters would be determined by the characteristics of your data and your business requirements. For TDengine to operate with the best performance, we strongly recommend that you create and configure different databases for data with different characteristics. This allows you, for example, to set up different storage and retention policies. When creating a database, there are a lot of parameters that can be configured such as, the days to keep data, the number of replicas, the size of the cache, time precision, the minimum and maximum number of rows in each data block, whether compression is enabled, the time range of the data in single data file and so on. An example is shown as follows:

From the perspective of application program, you need to consider:
1. The data size of each single write, also known as batch size. Generally speaking, higher batch size generates better writing performance. However, once the batch size is over a specific value, you will not get any additional benefit anymore. When using SQL to write into TDengine, it's better to put as much as possible data in single SQL. The maximum SQL length supported by TDengine is 1,048,576 bytes, i.e. 1 MB.

2. The number of concurrent connections. Normally more connections can get better result. However, once the number of connections exceeds the processing ability of the server side, the performance may downgrade.
3. The distribution of data to be written across tables or sub-tables. Writing to single table in one batch is more efficient than writing to multiple tables in one batch.
4. Data Writing Protocol.
- Prameter binding mode is more efficient than SQL because it doesn't have the cost of parsing SQL.
- Writing to known existing tables is more efficient than wirting to uncertain tables in automatic creating mode because the later needs to check whether the table exists or not before actually writing data into it
- Writing in SQL is more efficient than writing in schemaless mode because schemaless writing creats table automatically and may alter table schema
- Parameter binding mode is more efficient than SQL because it doesn't have the cost of parsing SQL.

- Writing in SQL is more efficient than writing in schemaless mode because schemaless writing creates table automatically and may alter table schema.
Application programs need to take care of the above factors and try to take advantage of them. The application progam should write to single table in each write batch. The batch size needs to be tuned to a proper value on a specific system. The number of concurrent connections needs to be tuned to a proper value too to achieve the best writing throughput.

Before creating an application to process time-series data with TDengine, consider the following:
1. Choose the method to connect to TDengine. TDengine offers a REST API that can be used with any programming language. It also has connectors for a variety of languages.
2. Design the data model based on your own use cases. Consider the main [concepts](/concept/) of TDengine, including "one table per data collection point" and the supertable. Learn about static labels, collected metrics, and subtables. Depending on the characteristics of your data and your requirements, you decide to create one or more databases and design a supertable schema that fit your data.
3. Decide how you will insert data. TDengine supports writing using standard SQL, but also supports schemaless writing, so that data can be written directly without creating tables manually.

The first column of the returned result set is the subtable name, and the subsequent columns are the tag columns.
If you already know the name of the tag column, you can use the following statement to get the value of the specified tag column.
```
taos> SELECT DISTINCT TBNAME, id FROM st1;
tbname | id |
===============================================
st1s1 | 1 |
st1s2 | 2 |
st1s3 | 3 |
Query OK, 3 rows in database (0.002891s)
```
It should be noted that DISTINCT and TBNAME in the SELECT statement are essential, and TDengine will optimize the statement according to them, so that it can return the tag value correctly and quickly even when there is no data or a lot of data.
### View the tag information of a subtable
```
taos> SHOW TAGS FROM st1s1;
table_name | db_name | stable_name | tag_name | tag_type | tag_value |
============================================================================================================
st1s1 | test | st1 | id | INT | 1 |
st1s1 | test | st1 | loc | VARCHAR(20) | beijing |
Query OK, 2 rows in database (0.003684s)
```
Similarly, you can also use the SELECT statement to query the value of the specified tag column.
```
taos> SELECT DISTINCT TBNAME, id, loc FROM st1s1;
tbname | id | loc |
==================================================
st1s1 | 1 | beijing |
Query OK, 1 rows in database (0.001884s)

- `INTERP` is used to get the value that matches the specified time slice from a column. If no such value exists an interpolation value will be returned based on `FILL` parameter.
- The input data of `INTERP` is the value of the specified column and a `where` clause can be used to filter the original data. If no `where` condition is specified then all original data is the input.
- The output time range of `INTERP` is specified by `RANGE(timestamp1,timestamp2)` parameter, with timestamp1<=timestamp2. timestamp1 is the starting point of the output time range and must be specified. timestamp2 is the ending point of the output time range and must be specified.
- The number of rows in the result set of `INTERP` is determined by the parameter `EVERY`. Starting from timestamp1, one interpolation is performed for every time interval specified `EVERY` parameter.
- The number of rows in the result set of `INTERP` is determined by the parameter `EVERY`. Starting from timestamp1, one interpolation is performed for every time interval specified `EVERY` parameter. The parameter `EVERY` must be an integer, with no quotes, with a time unit of: b(nanosecond), u(microsecond), a(millisecond)), s(second), m(minute), h(hour), d(day), or w(week). For example, `EVERY(500a)` will interpolate every 500 milliseconds.
- Interpolation is performed based on `FILL` parameter.
- `INTERP` can only be used to interpolate in single timeline. So it must be used with `partition by tbname` when it's used on a STable.
- Pseudo column `_irowts` can be used along with `INTERP` to return the timestamps associated with interpolation points(support after version 3.0.1.4).

## Introduction
# Introduction
taosBenchmark (formerly taosdemo ) is a tool for testing the performance of TDengine products. taosBenchmark can test the performance of TDengine's insert, query, and subscription functions and simulate large amounts of data generated by many devices. taosBenchmark can be configured to generate user defined databases, supertables, subtables, and the time series data to populate these for performance benchmarking. taosBenchmark is highly configurable and some of the configurations include the time interval for inserting data, the number of working threads and the capability to insert disordered data. The installer provides taosdemo as a soft link to taosBenchmark for compatibility with past users.
......@@ -23,7 +23,7 @@ There are two ways to install taosBenchmark:
TaosBenchmark needs to be executed on the terminal of the operating system, it supports two configuration methods: [Command-line arguments](#command-line-arguments-in-detail) and [JSON configuration file](#configuration-file-parameters-in-detail). These two methods are mutually exclusive. Users can use `-f <json file>` to specify a configuration file. When running taosBenchmark with command-line arguments to control its behavior, users should use other parameters for configuration, but not the `-f` parameter. In addition, taosBenchmark offers a special way of running without parameters.
taosBenchmark supports the complete performance testing of TDengine by providing functionally to write, query, and subscribe. These three functions are mutually exclusive, users can only select one of them each time taosBenchmark runs. The query and subscribe functionalities are only configurable using a json configuration file by specifying the parameter `filetype`, while write can be performed through both the command-line and a configuration file. If you want to test the performance of queries or data subscriptionm configure taosBenchmark with the configuration file. You can modify the value of the `filetype` parameter to specify the function that you want to test.

不同类型的数据采集点往往具有不同的数据特征，包括数据采集频率的高低，数据保留时间的长短，副本的数目，数据块的大小，是否允许更新数据等等。为了在各种场景下 TDengine 都能最大效率的工作，TDengine 建议将不同数据特征的表创建在不同的库里，因为每个库可以配置不同的存储策略。创建一个库时，除 SQL 标准的选项外，还可以指定保留时长、副本数、缓存大小、时间精度、文件块里最大最小记录条数、是否压缩、一个数据文件覆盖的天数等多种参数。比如：

## 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个超级表。以[表 1](/tdinternal/arch#model_table1) 中的智能电表为例，可以使用如下的 SQL 命令创建超级表：
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个超级表。以 [表 1](/concept) 中的智能电表为例，可以使用如下的 SQL 命令创建超级表：
```sql
CREATE STABLE meters (ts timestamp, current float, voltage int, phase float) TAGS (location binary(64), groupId int);
```
与创建普通表一样，创建超级表时，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 [TDengine SQL 的超级表管理](/taos-sql/stable) 章节。

每一种类型的数据采集点需要建立一个超级表，因此一个物联网系统，往往会有多个超级表。对于电网，我们就需要对智能电表、变压器、母线、开关等都建立一个超级表。在物联网中，一个设备就可能有多个数据采集点（比如一台风力发电的风机，有的采集点采集电流、电压等电参数，有的采集点采集温度、湿度、风向等环境参数），这个时候，对这一类型的设备，需要建立多张超级表。
一张超级表最多容许 4096 列，如果一个采集点采集的物理量个数超过 4096，需要建多张超级表来处理。一个系统可以有多个 DB，一个 DB 里可以有一到多个超级表。

## 创建表
TDengine 对每个数据采集点需要独立建表。与标准的关系型数据库一样，一张表有表名，Schema，但除此之外，还可以带有一到多个标签。创建时，需要使用超级表做模板，同时指定标签的具体值。以[表 1](/tdinternal/arch#model_table1)中的智能电表为例，可以使用如下的 SQL 命令建表：

```sql
CREATE TABLE d1001 USING meters TAGS ("California.SanFrancisco", 2);
```
其中 d1001 是表名，meters 是超级表的表名，后面紧跟标签 Location 的具体标签值 "California.SanFrancisco"，标签 groupId 的具体标签值 2。虽然在创建表时，需要指定标签值，但可以事后修改。详细细则请见 [TDengine SQL 的表管理](/taos-sql/table) 章节。

TDengine 建议将数据采集点的全局唯一 ID 作为表名(比如设备序列号）。但对于有的场景，并没有唯一的 ID，可以将多个 ID 组合成一个唯一的 ID。不建议将具有唯一性的 ID 作为标签值。

### 自动建表
在某些特殊场景中，用户在写数据时并不确定某个数据采集点的表是否存在，此时可在写入数据时使用自动建表语法来创建不存在的表，若该表已存在则不会建立新表且后面的 USING 语句被忽略。比如：
```sql
INSERT INTO d1001 USING meters TAGS ("California.SanFrancisco", 2) VALUES (now, 10.2, 219, 0.32);
INSERT INTO d1001 USING meters TAGS ("California.SanFrancisco", 2) VALUES (NOW, 10.2, 219, 0.32);
```
上述 SQL 语句将记录`(now, 10.2, 219, 0.32)`插入表 d1001。如果表 d1001 还未创建，则使用超级表 meters 做模板自动创建，同时打上标签值 `"California.SanFrancisco", 2`。

开发一个应用，如果你准备采用TDengine作为时序数据处理的工具，那么有如下几个事情要做：
1. 确定应用到TDengine的链接方式。无论你使用何种编程语言，你总可以使用REST接口, 但也可以使用每种编程语言独有的连接器方便的进行链接。
开发一个应用，如果你准备采用 TDengine 作为时序数据处理的工具，那么有如下几个事情要做：
1. 确定应用到 TDengine 的连接方式。无论你使用何种编程语言，你总是可以使用 REST 接口, 但也可以使用每种编程语言独有的连接器进行方便的连接。
2. 根据自己的应用场景，确定数据模型。根据数据特征，决定建立一个还是多个库；分清静态标签、采集量，建立正确的超级表，建立子表。
3. 决定插入数据的方式。TDengine支持使用标准的SQL写入，但同时也支持schemaless模式写入，这样不用手工建表，可以将数据直接写入。
4. 根据业务要求，看需要撰写哪些SQL查询语句。

4. 根据业务要求，看需要撰写哪些 SQL 查询语句。
5. 如果你要基于时序数据做轻量级的实时统计分析，包括各种监测看板，那么建议你采用 TDengine 3.0 的流式计算功能，而不用额外部署 Spark, Flink 等复杂的流式计算系统。
6. 如果你的应用有模块需要消费插入的数据，希望有新的数据插入时，就能获取通知，那么建议你采用TDengine提供的数据订阅功能，而无需专门部署Kafka或其他消息队列软件。
7. 在很多场景下(如车辆管理)，应用需要获取每个数据采集点的最新状态，那么建议你采用TDengine的cache功能，而不用单独部署Redis等缓存软件。
8. 如果你发现TDengine的函数无法满足你的要求，那么你可以使用用户自定义函数来解决问题。

本部分内容就是按照上述的顺序组织的。为便于理解，TDengine为每个功能为每个支持的编程语言都提供了示例代码。如果你希望深入了解SQL的使用，需要查看[SQL手册](/taos-sql/)。如果想更深入地了解各连接器的使用，请阅读[连接器参考指南](../connector/)。如果还希望想将TDengine与第三方系统集成起来，比如Grafana, 请参考[第三方工具](../third-party/)。

### 获取超级表中所有子表的标签信息
```
taos> SHOW TABLE TAGS FROM st1;

st1s1 | 1 | beijing |
st1s2 | 2 | shanghai |
st1s3 | 3 | guangzhou |
Query OK, 3 rows in database (0.004455s)

返回结果集的第一列为子表名，后续列为标签列。
如果已经知道标签列的名称，可以使用下面的语句来获取指定标签列的值。
```
taos> SELECT DISTINCT TBNAME, id FROM st1;
tbname | id |
===============================================
st1s1 | 1 |
st1s2 | 2 |
st1s3 | 3 |
Query OK, 3 rows in database (0.002891s)
```
需要注意，SELECT 语句中的 DISTINCT 和 TBNAME 都是必不可少的，TDengine 会根据它们对语句进行优化，使之在没有数据或数据非常多的情况下都可以正确并快速的返回标签值。
### 获取某个子表的标签信息
```
taos> SHOW TAGS FROM st1s1;

同样的，也可以用 SELECT 语句来查询指定标签列的值。

对于数据一致性要求更高的场景，异步数据复制提供的最终一致性无法满足要求。因此 TDengine 提供同步复制的机制供用户选择。在创建数据库时，除指定副本数 replica 之外，用户还需要指定新的参数 strict。如果 strict 等于 1，它表示每次 leader 转发给副本时，需要等待半数以上副本达成一致后，才能通知应用，数据在 follower 已经写入成功。如果在一定的时间内，得不到半数以上副本的确认，leader vnode 将返回错误给应用。
对于数据一致性要求更高的场景，异步数据复制提供的最终一致性无法满足要求。因此 TDengine 提供同步复制的机制供用户选择。在创建数据库时，除指定副本数 `replica` 之外，用户还需要指定新的参数 `strict`。如果 `strict` 等于 1，它表示每次 leader 转发给副本时，需要等待半数以上副本达成一致后，才能通知应用，数据在 follower 已经写入成功。如果在一定的时间内，得不到半数以上副本的确认，leader vnode 将返回错误给应用。
采用同步复制，系统的性能会有所下降，而且 latency 会增加。因为元数据要强一致，mnode 之间的数据同步缺省就是采用的同步复制。

TDengine 采用数据驱动的方式让缓存中的数据写入硬盘进行持久化存储。当 vnode 中缓存的数据达到一定规模时，为了不阻塞后续数据的写入，TDengine 也会拉起落盘线程将缓存的数据写入持久化存储。TDengine 在数据落盘时会打开新的数据库日志文件，在落盘成功后则会删除老的数据库日志文件，避免日志文件无限制地增长。
为充分利用时序数据特点，TDengine 将一个 vnode 保存在持久化存储的数据切分成多个文件，每个文件只保存固定天数的数据，这个天数由系统配置参数 days 决定。切分成多个文件后，给定查询的起止日期，无需任何索引，就可以立即定位需要打开哪些数据文件，大大加快读取速度。
为充分利用时序数据特点，TDengine 将一个 vnode 保存在持久化存储的数据切分成多个文件，每个文件只保存固定天数的数据，这个天数由系统配置参数 `duration` 决定。切分成多个文件后，给定查询的起止日期，无需任何索引，就可以立即定位需要打开哪些数据文件，大大加快读取速度。
对于采集的数据，一般有保留时长，这个时长由系统配置参数 keep 决定。超过这个设置天数的数据文件，将被系统自动删除，释放存储空间。
对于采集的数据，一般有保留时长，这个时长由系统配置参数 `keep` 决定。超过这个设置天数的数据文件，将被系统自动删除，释放存储空间。
给定 days 与 keep 两个参数，一个典型工作状态的 vnode 中总的数据文件数为：向上取整 `(keep/days)+1` 个。总的数据文件个数不宜过大，也不宜过小。10 到 100 以内合适。基于这个原则，可以设置合理的 days。目前的版本，参数 keep 可以修改，但对于参数 days，一旦设置后，不可修改。
给定 `duration` 与 `keep` 两个参数，一个典型工作状态的 vnode 中总的数据文件数为：向上取整 `(keep/duration)+1` 个。总的数据文件个数不宜过大，也不宜过小。10 到 100 以内合适。基于这个原则，可以设置合理的 `duration`。目前的版本，参数 `keep` 可以修改，但对于参数 `duration`，一旦设置后，不可修改。
在每个数据文件里，一张表的数据是一块一块存储的。一张表可以有一到多个数据文件块。在一个文件块里，数据是列式存储的，占用的是一片连续的存储空间，这样大大提高读取速度。文件块的大小由系统参数 maxRows （每块最大记录条数）决定，缺省值为 4096。这个值不宜过大，也不宜过小。过大，定位具体时间段的数据的搜索时间会变长，影响读取速度；过小，数据块的索引太大，压缩效率偏低，也影响读取速度。
