**虚拟节点(vnode)**: 为更好的支持数据分片、负载均衡，防止数据过热或倾斜，数据节点被虚拟化成多个虚拟节点(vnode，图中V2, V3, V4等)。每个 vnode 都是一个相对独立的工作单元，是时序数据存储的基本单元，具有独立的运行线程、内存空间与持久化存储的路径。一个 vnode 包含一定数量的表（数据采集点）。当创建一张新表时，系统会检查是否需要创建新的 vnode。一个数据节点上能创建的 vnode 的数量取决于该数据节点所在物理节点的硬件资源。一个 vnode 只属于一个DB，但一个DB可以有多个 vnode。一个 vnode 除存储的时序数据外，也保存有所包含的表的schema、标签值等。一个虚拟节点由所属的数据节点的EP，以及所属的VGroup ID在系统内唯一标识，由管理节点创建并管理。
**管理节点(mnode):** 一个虚拟的逻辑单元，负责所有数据节点运行状态的监控和维护，以及节点之间的负载均衡(图中M)。同时，管理节点也负责元数据(包括用户、数据库、表、静态标签等)的存储和管理，因此也称为 Meta Node。TDengine 集群中可配置多个(最多不超过5个) mnode，它们自动构建成为一个虚拟管理节点组(图中M0, M1, M2)。mnode 间采用 master/slave 的机制进行管理，而且采取强一致方式进行数据同步, 任何数据更新操作只能在 Master 上进行。mnode 集群的创建由系统自动完成，无需人工干预。每个dnode上至多有一个mnode，由所属的数据节点的EP来唯一标识。每个dnode通过内部消息交互自动获取整个集群中所有 mnode 所在的 dnode 的EP。

**虚拟节点组(VGroup):** 不同数据节点上的 vnode 可以组成一个虚拟节点组(vnode group)来保证系统的高可靠。虚拟节点组内采取master/slave的方式进行管理。写操作只能在 master vnode 上进行，系统采用异步复制的方式将数据同步到 slave vnode，这样确保了一份数据在多个物理节点上有拷贝。一个 vgroup 里虚拟节点个数就是数据的副本数。如果一个DB的副本数为N，系统必须有至少N个数据节点。副本数在创建DB时通过参数 replica 可以指定，缺省为1。使用 TDengine 的多副本特性，可以不再需要昂贵的磁盘阵列等存储设备，就可以获得同样的数据高可靠性。虚拟节点组由管理节点创建、管理，并且由管理节点分配一个系统唯一的ID，VGroup ID。如果两个虚拟节点的vnode group ID相同，说明他们属于同一个组，数据互为备份。虚拟节点组里虚拟节点的个数是可以动态改变的，容许只有一个，也就是没有数据复制。VGroup ID是永远不变的，即使一个虚拟节点组被删除，它的ID也不会被收回重复利用。

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，名为 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，当副本数为偶数时，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。
总之，在目前版本下，TDengine 建议在双副本环境要配置 Arbitrator，以提升系统的可用性。

使用 TDengine 来搭建一个物联网大数据平台，计算资源、存储资源需要根据业务场景进行规划。下面分别讨论系统运行所需要的内存、CPU 以及硬盘空间。
### 内存需求
每个DB可以创建固定数目的vgroup，默认与CPU核数相同，可通过maxVgroupsPerDb配置；vgroup中的每个副本会是一个vnode；每个vnode会占用固定大小的内存（大小与数据库的配置参数blocks和cache有关)；每个Table会占用与标签总长度有关的内存；此外，系统会有一些固定的内存开销。因此，每个DB需要的系统内存可通过如下公式计算：

```
Memory Size = maxVgroupsPerDb * (blocks * cache + 10Mb) + numOfTables * (tagSizePerTable + 0.5Kb)
Memory Size = maxVgroupsPerDb * (blocks * cache + 10MB) + numOfTables * (tagSizePerTable + 0.5KB)
```
示例：假设是4核机器，cache是缺省大小16M, blocks是缺省值6，假设有10万张表，标签总长度是256字节，则总的内存需求为：4\*(16\*6+10) + 100000\*(0.25+0.5)/1000 = 499M。
示例：假设是 4 核机器，cache 是缺省大小 16M, blocks 是缺省值 6，假设有 10 万张表，标签总长度是 256 字节，则总的内存需求为：4 \* (16 \* 6 + 10) + 100000 \* (0.25 + 0.5) / 1000 = 499M。
实际运行的系统往往会根据数据特点的不同，将数据存放在不同的DB里。因此做规划时，也需要考虑。

如果内存充裕，可以加大Blocks的配置，这样更多数据将保存在内存里，提高查询速度。

### CPU需求
### CPU 需求
CPU的需求取决于如下两方面：
CPU 的需求取决于如下两方面：
* __数据插入__ TDengine单核每秒能至少处理一万个插入请求。每个插入请求可以带多条记录，一次插入一条记录与插入10条记录，消耗的计算资源差别很小。因此每次插入，条数越大，插入效率越高。如果一个插入请求带200条以上记录，单核就能达到每秒插入100万条记录的速度。但对前端数据采集的要求越高，因为需要缓存记录，然后一批插入。
* __查询需求__ TDengine提供高效的查询，但是每个场景的查询差异很大，查询频次变化也很大，难以给出客观数字。需要用户针对自己的场景，写一些查询语句，才能确定。

* __查询需求__ TDengine 提供高效的查询，但是每个场景的查询差异很大，查询频次变化也很大，难以给出客观数字。需要用户针对自己的场景，写一些查询语句，才能确定。
因此仅对数据插入而言，CPU是可以估算出来的，但查询所耗的计算资源无法估算。在实际运营过程中，不建议CPU使用率超过50%，超过后，需要增加新的节点，以获得更多计算资源。

### 存储需求
TDengine相对于通用数据库，有超高的压缩比，在绝大多数场景下，TDengine的压缩比不会低于5倍，有的场合，压缩比可达到10倍以上，取决于实际场景的数据特征。压缩前的原始数据大小可通过如下方式计算：
TDengine 相对于通用数据库，有超高的压缩比，在绝大多数场景下，TDengine 的压缩比不会低于 5 倍，有的场合，压缩比可达到 10 倍以上，取决于实际场景的数据特征。压缩前的原始数据大小可通过如下方式计算：
```
Raw DataSize = numOfTables * rowSizePerTable * rowsPerTable
```
示例：1000万台智能电表，每台电表每15分钟采集一次数据，每次采集的数据128字节，那么一年的原始数据量是：10000000\*128\*24\*60/15\*365 = 44.8512T。TDengine大概需要消耗44.851/5=8.97024T空间。

用户可以通过参数keep，设置数据在磁盘中的最大保存时长。为进一步减少存储成本，TDengine还提供多级存储，最冷的数据可以存放在最廉价的存储介质上，应用的访问不用做任何调整，只是读取速度降低了。

### 物理机或虚拟机台数
根据上面的内存、CPU、存储的预估，就可以知道整个系统需要多少核、多少内存、多少存储空间。如果数据副本数不为1，总需求量需要再乘以副本数。

因为TDengine具有很好的水平扩展能力，根据总量，再根据单个物理机或虚拟机的资源，就可以轻松决定需要购置多少台物理机或虚拟机了。

本章节SQL语法遵循如下约定：
TAOS SQL 不支持关键字的缩写，例如 DESCRIBE 不能缩写为 DESC。
- < > 里的内容是用户需要输入的，但不要输入<>本身
- [ ]表示内容为可选项，但不能输入[]本身
- | 表示多选一，选择其中一个即可，但不能输入|本身

- [ ] 表示内容为可选项，但不能输入 [] 本身

- … 表示前面的项可重复多个
为更好地说明SQL语法的规则及其特点，本文假设存在一个数据集。以智能电表(meters)为例，假设每个智能电表采集电流、电压、相位三个量。其建模如下：

- 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：
* 不进行填充：NONE(默认填充模式)。
* 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)。

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。
时间聚合也常被用于连续查询场景，可以参考文档 [连续查询(Continuous Query)](https://www.taosdata.com/cn/documentation/advanced-features#continuous-query)。

从 2.0.8.0 开始，TDengine 支持更新已经写入数据的功能。使用更新功能需要在创建数据库时使用 UPDATE 1 参数，之后可以使用 INSERT INTO 命令更新已经写入的相同时间戳数据。UPDATE 参数不支持 ALTER DATABASE 命令修改。没有使用 UPDATE 1 参数创建的数据库，写入相同时间戳的数据不会修改之前的数据，也不会报错。
另需注意，在 UPDATE 设置为 0 时，后发送的相同时间戳的数据会被直接丢弃，但并不会报错，而且仍然会被计入 affected rows （所以不能利用 INSERT 指令的返回信息进行时间戳查重）。这样设计的主要原因是，TDengine 把写入的数据看做一个数据流，无论时间戳是否出现冲突，TDengine 都认为产生数据的原始设备真实地产生了这样的数据。UPDATE 参数只是控制这样的流数据在进行持久化时要怎样处理——UPDATE 为 0 时，表示先写入的数据覆盖后写入的数据；而 UPDATE 为 1 时，表示后写入的数据覆盖先写入的数据。这种覆盖关系如何选择，取决于对数据的后续使用和统计中，希望以先还是后生成的数据为准。
## 10. 我怎么创建超过1024列的表？
使用2.0及其以上版本，默认支持1024列；2.0之前的版本，TDengine最大允许创建250列的表。但是如果确实超过限值，建议按照数据特性，逻辑地将这个宽表分解成几个小表。
