title: Cache
description: "The latest row of each table is kept in cache to provide high performance query of latest state."
description: "Caching System inside TDengine"
---
To achieve the purpose of high performance data writing and querying, TDengine employs a lot of caching technologies in both server side and client side.
## Write Cache
The cache management policy in TDengine is First-In-First-Out (FIFO). FIFO is also known as insert driven cache management policy and it is different from read driven cache management, which is more commonly known as Least-Recently-Used (LRU). FIFO simply stores the latest data in cache and flushes the oldest data in cache to disk, when the cache usage reaches a threshold. In IoT use cases, it is the current state i.e. the latest or most recent data that is important. The cache policy in TDengine, like much of the design and architecture of TDengine, is based on the nature of IoT data.
Caching the latest data provides the capability of retrieving data in milliseconds. With this capability, TDengine can be configured properly to be used as a caching system without deploying another separate caching system. This simplifies the system architecture and minimizes operational costs. The cache is emptied after TDengine is restarted. TDengine does not reload data from disk into cache, like a key-value caching system.
The memory space used by each vnode as write cache is determined when creating a database. Parameter `vgroups` and `buffer` can be used to specify the number of vnode and the size of write cache for each vnode when creating the database. Then, the total size of write cache for this database is `vgroups * buffer`.
```sql
create database db0 vgroups 100 buffer 16MB
```
The above statement creates a database of 100 vnodes while each vnode has a write cache of 16MB.
Even though in theory it's always better to have a larger cache, the extra effect would be very minor once the size of cache grows beyond a threshold. So normally it's enough to use the default value of `buffer` parameter.
## Read Cache
The memory space used by the TDengine cache is fixed in size and configurable. It should be allocated based on application requirements and system resources. An independent memory pool is allocated for and managed by each vnode (virtual node) in TDengine. There is no sharing of memory pools between vnodes. All the tables belonging to a vnode share all the cache memory of the vnode.
When creating a database, it's also possible to specify whether to cache the latest data of each sub table, using parameter `cachelast`. There are 3 cases:
- 0: No cache for latest data
- 1: The last row of each table is cached, `last_row` function can benefit significantly from it
- 2: The latest non-NULL value of each column for each table is cached, `last` function can benefit very much when there is no `where`, `group by`, `order by` or `interval` clause
- 3: Bot hthe last row and the latest non-NULL value of each column for each table are cached, identical to the behavior of both 1 and 2 are set together
The memory pool is divided into blocks and data is stored in row format in memory and each block follows FIFO policy. The size of each block is determined by configuration parameter `cache` and the number of blocks for each vnode is determined by the parameter `blocks`. For each vnode, the total cache size is `cache * blocks`. A cache block needs to ensure that each table can store at least dozens of records, to be efficient.
`last_row` function can be used to retrieve the last row of a table or a STable to quickly show the current state of devices on monitoring screen. For example the below SQL statement retrieves the latest voltage of all meters in San Francisco, California.
## Meta Cache
To process data writing and querying efficiently, each vnode caches the metadata that's already retrieved. Parameters `pages` and `pagesize` are used to specify the size of metadata cache for each vnode.
```sql
select last_row(voltage) from meters where location='California.SanFrancisco';
create database db0 pages 128 pagesize 16kb
```
The above statement will create a database db0 each of whose vnode is allocated a meta cache of `128 * 16 KB = 2 MB` .
## File System Cache
TDengine utilizes WAL to provide basic reliability. The essential of WAL is to append data in a disk file, so the file system cache also plays an important role in the writing performance. Parameter `wal` can be used to specify the policy of writing WAL, there are 2 cases:
- 1: Write data to WAL without calling fsync, the data is actually written to the file system cache without flushing immediately, in this way you can get better write performance
- 2: Write data to WAL and invoke fsync, the data is immediately flushed to disk, in this way you can get higher reliability
## Client Cache
To improve the overall efficiency of processing data, besides the above caches, the core library `libtaos.so` (also referred to as `taosc`) which all client programs depend on also has its own cache. `taosc` caches the metadata of the databases, super tables, tables that the invoking client has accessed, plus other critical metadata such as the cluster topology.
When multiple client programs are accessing a TDengine cluster, if one of the clients modifies some metadata, the cache may become invalid in other clients. If this case happens, the client programs need to "reset query cache" to invalidate the whole cache so that `taosc` is enforced to repull the metadata it needs to rebuild the cache.

- Only a vnode in normal state, i.e. leader or follower, can be moved. vnode can't be moved when its in status offline, unsynced or syncing.
- Before moving a vnode, it's necessary to make sure the target dnode has enough resources: CPU, memory and disk.

title: High Availability and Load Balancing
---
## High Availability of Vnode
High availability of vnode and mnode can be achieved through replicas in TDengine.
A TDengine cluster can have multiple databases. Each database has a number of vnodes associated with it. A different number of replicas can be configured for each DB. When creating a database, the parameter `replica` is used to specify the number of replicas. The default value for `replica` is 1. Naturally, a single replica cannot guarantee high availability since if one node is down, the data service is unavailable. Note that the number of dnodes in the cluster must NOT be lower than the number of replicas set for any DB, otherwise the `create table` operation will fail with error "more dnodes are needed". The SQL statement below is used to create a database named "demo" with 3 replicas.
```sql
CREATE DATABASE demo replica 3;
```
The data in a DB is divided into multiple shards and stored in multiple vgroups. The number of vnodes in each vgroup is determined by the number of replicas set for the DB. The vnodes in each vgroup store exactly the same data. For the purpose of high availability, the vnodes in a vgroup must be located in different dnodes on different hosts. As long as over half of the vnodes in a vgroup are in an online state, the vgroup is able to provide data access. Otherwise the vgroup can't provide data access for reading or inserting data.
There may be data for multiple DBs in a dnode. When a dnode is down, multiple DBs may be affected. While in theory, the cluster will provide data access for reading or inserting data if over half the vnodes in vgroups are online, because of the possibly complex mapping between vnodes and dnodes, it is difficult to guarantee that the cluster will work properly if over half of the dnodes are online.
## High Availability of Mnode
Each TDengine cluster is managed by `mnode`, which is a module of `taosd`. For the high availability of mnode, multiple mnodes can be configured using system parameter `numOfMNodes`. The valid range for `numOfMnodes` is [1,3]. To ensure data consistency between mnodes, data replication between mnodes is performed synchronously.
There may be multiple dnodes in a cluster, but only one mnode can be started in each dnode. Which one or ones of the dnodes will be designated as mnodes is automatically determined by TDengine according to the cluster configuration and system resources. The command `show mnodes` can be executed in TDengine `taos` to show the mnodes in the cluster.
```sql
SHOW MNODES;
```
The end point and role/status (leader, follower, unsynced, or offline) of all mnodes can be shown by the above command. When the first dnode is started in a cluster, there must be one mnode in this dnode. Without at least one mnode, the cluster cannot work. If `numOfMNodes` is configured to 2, another mnode will be started when the second dnode is launched.
For the high availability of mnode, `numOfMnodes` needs to be configured to 2 or a higher value. Because the data consistency between mnodes must be guaranteed, the replica confirmation parameter `quorum` is set to 2 automatically if `numOfMNodes` is set to 2 or higher.
:::note
If high availability is important for your system, both vnode and mnode must be configured to have multiple replicas.
:::
## Load Balancing
Load balancing will be triggered in 3 cases without manual intervention.
- When a new dnode joins the cluster, automatic load balancing may be triggered. Some data from other dnodes may be transferred to the new dnode automatically.
- When a dnode is removed from the cluster, the data from this dnode will be transferred to other dnodes automatically.
- When a dnode is too hot, i.e. too much data has been stored in it, automatic load balancing may be triggered to migrate some vnodes from this dnode to other dnodes.
:::tip
Automatic load balancing is controlled by the parameter `balance`, 0 means disabled and 1 means enabled. This is set in the file [taos.cfg](https://docs.tdengine.com/reference/config/#balance).
:::
## Dnode Offline
When a dnode is offline, it can be detected by the TDengine cluster. There are two cases:
- The dnode comes online before the threshold configured in `offlineThreshold` is reached. The dnode is still in the cluster and data replication is started automatically. The dnode can work properly after the data sync is finished.
- If the dnode has been offline over the threshold configured in `offlineThreshold` in `taos.cfg`, the dnode will be removed from the cluster automatically. A system alert will be generated and automatic load balancing will be triggered if `balance` is set to 1. When the removed dnode is restarted and becomes online, it will not join the cluster automatically. The system administrator has to manually join the dnode to the cluster.
:::note
If all the vnodes in a vgroup (or mnodes in mnode group) are in offline or unsynced status, the leader node can only be voted on, after all the vnodes or mnodes in the group become online and can exchange status. Following this, the vgroup (or mnode group) is able to provide service.
:::
## Arbitrator
The "arbitrator" component is used to address the special case when the number of replicas is set to an even number like 2,4 etc. If half of the vnodes in a vgroup don't work, it is impossible to vote and select a leader node. This situation also applies to mnodes if the number of mnodes is set to an even number like 2,4 etc.
To resolve this problem, a new arbitrator component named `tarbitrator`, an abbreviation of TDengine Arbitrator, was introduced. The `tarbitrator` simulates a vnode or mnode but it's only responsible for network communication and doesn't handle any actual data access. As long as more than half of the vnode or mnode, including Arbitrator, are available the vnode group or mnode group can provide data insertion or query services normally.
Normally, it's prudent to configure the replica number for each DB or system parameter `numOfMNodes` to be an odd number. However, if a user is very sensitive to storage space, a replica number of 2 plus arbitrator component can be used to achieve both lower cost of storage space and high availability.
Arbitrator component is installed with the server package. For details about how to install, please refer to [Install](/operation/pkg-install). The `-p` parameter of `tarbitrator` can be used to specify the port on which it provides service.
In the configuration file `taos.cfg` of each dnode, parameter `arbitrator` needs to be configured to the end point of the `tarbitrator` process. Arbitrator component will be used automatically if the replica is configured to an even number and will be ignored if the replica is configured to an odd number.
Arbitrator can be shown by executing command in TDengine CLI `taos` with its role shown as "arb".

The data in a DB is divided into multiple shards and stored in multiple vgroups. The number of vnodes in each vgroup is determined by the number of replicas set for the DB. The vnodes in each vgroup store exactly the same data. For the purpose of high availability, the vnodes in a vgroup must be located in different dnodes on different hosts. As long as over half of the vnodes in a vgroup are in an online state, the vgroup is able to provide data access. Otherwise the vgroup can't provide data access for reading or inserting data.
There may be data for multiple DBs in a dnode. When a dnode is down, multiple DBs may be affected. While in theory, the cluster will provide data access for reading or inserting data if over half the vnodes in vgroups are online, because of the possibly complex mapping between vnodes and dnodes, it is difficult to guarantee that the cluster will work properly if over half of the dnodes are online.
## High Availability of Mnode
Each TDengine cluster is managed by `mnode`, which is a module of `taosd`. For the high availability of mnode, multiple mnodes can be configured in the system. When a TDengine cluster is started from scratch, there is only one `mnode`, then you can use command `create mnode` to and start corresponding dnode to add more mnodes.
```sql
SHOW MNODES;
```
The end point and role/status (leader, follower, candidate, offline) of all mnodes can be shown by the above command. When the first dnode is started in a cluster, there must be one mnode in this dnode. Without at least one mnode, the cluster cannot work.
From TDengine 3.0.0, RAFT procotol is used to guarantee the high availability, so the number of mnodes is should be 1 or 3.

sidebar_label: Load Balance
title: Load Balance
---
The load balance in TDengine is mainly about processing data series data. TDengine employes builtin hash algorithm to distribute all the tables, sub-tables and their data of a database across all the vgroups that belongs to the database. Each table or sub-table can only be handled by a single vgroup, while each vgroup can process multiple table or sub-table.
The number of vgroup can be specified when creating a database, using the parameter `vgroups`.
```sql
create database db0 vgroups 100;
```
The proper value of `vgroups` depends on available system resources. Assuming there is only one database to be created in the system, then the number of `vgroups` is determined by the available resources from all dnodes. In principle more vgroups can be created if you have more CPU and memory. Disk I/O is another important factor to consider. Once the bottleneck shows on disk I/O, more vgroups may downgrad the system performance significantly. If multiple databases are to be created in the system, then the total number of `vroups` of all the databases are dependent on the available system resources. It needs to be careful to distribute vgroups among these databases, you need to consider the number of tables, data writing frequency, size of each data row for all these databases. A recommended practice is to firstly choose a starting number for `vgroups`, for example double of the number of CPU cores, then try to adjust and optimize system configurations to find the best setting for `vgroups`, then distribute these vgroups among databases.
Furthermode, TDengine distributes the vgroups of each database equally among all dnodes. In case of replica 3, the distrubtion is even more complex, TDengine tries its best to prevent any dnode from becoming a bottleneck.
TDegnine utilizes the above ways to achieve load balance in a cluster, and finally achieve higher throughput.
Once the load balance is achieved, after some operations like deleting tables or droping databases, the load across all dnodes may become inbalanced, the method of rebalance will be provided in later versions. However, even without explicit rebalancing, TDengine will try its best to achieve new balance without manual interfering when a new database is created.

title: 高可用与负载均衡
---
## Vnode 的高可用性
TDengine 通过多副本的机制来提供系统的高可用性，包括 vnode 和 mnode 的高可用性。
vnode 的副本数是与 DB 关联的，一个集群里可以有多个 DB，根据运营的需求，每个 DB 可以配置不同的副本数。创建数据库时，通过参数 replica 指定副本数（缺省为 1）。如果副本数为 1，系统的可靠性无法保证，只要数据所在的节点宕机，就将无法提供服务。集群的节点数必须大于等于副本数，否则创建表时将返回错误“more dnodes are needed”。比如下面的命令将创建副本数为 3 的数据库 demo：
```sql
CREATE DATABASE demo replica 3;
```
一个 DB 里的数据会被切片分到多个 vnode group，vnode group 里的 vnode 数目就是 DB 的副本数，同一个 vnode group 里各 vnode 的数据是完全一致的。为保证高可用性，vnode group 里的 vnode 一定要分布在不同的数据节点 dnode 里（实际部署时，需要在不同的物理机上），只要一个 vnode group 里超过半数的 vnode 处于工作状态，这个 vnode group 就能正常的对外服务。
一个数据节点 dnode 里可能有多个 DB 的数据，因此一个 dnode 离线时，可能会影响到多个 DB。如果一个 vnode group 里的一半或一半以上的 vnode 不工作，那么该 vnode group 就无法对外服务，无法插入或读取数据，这样会影响到它所属的 DB 的一部分表的读写操作。
因为 vnode 的引入，无法简单地给出结论：“集群中过半数据节点 dnode 工作，集群就应该工作”。但是对于简单的情形，很好下结论。比如副本数为 3，只有三个 dnode，那如果仅有一个节点不工作，整个集群还是可以正常工作的，但如果有两个数据节点不工作，那整个集群就无法正常工作了。
## Mnode 的高可用性
TDengine 集群是由 mnode（taosd 的一个模块，管理节点）负责管理的，为保证 mnode 的高可用，可以配置多个 mnode 副本，副本数由系统配置参数 numOfMnodes 决定，有效范围为 1-3。为保证元数据的强一致性，mnode 副本之间是通过同步的方式进行数据复制的。
一个集群有多个数据节点 dnode，但一个 dnode 至多运行一个 mnode 实例。多个 dnode 情况下，哪个 dnode 可以作为 mnode 呢？这是完全由系统根据整个系统资源情况，自动指定的。用户可通过 CLI 程序 taos，在 TDengine 的 console 里，执行如下命令：
```sql
SHOW MNODES;
```
来查看 mnode 列表，该列表将列出 mnode 所处的 dnode 的 End Point 和角色（master，slave，unsynced 或 offline）。当集群中第一个数据节点启动时，该数据节点一定会运行一个 mnode 实例，否则该数据节点 dnode 无法正常工作，因为一个系统是必须有至少一个 mnode 的。如果 numOfMnodes 配置为 2，启动第二个 dnode 时，该 dnode 也将运行一个 mnode 实例。
为保证 mnode 服务的高可用性，numOfMnodes 必须设置为 2 或更大。因为 mnode 保存的元数据必须是强一致的，如果 numOfMnodes 大于 2，复制参数 quorum 自动设为 2，也就是说，至少要保证有两个副本写入数据成功，才通知客户端应用写入成功。
:::note
一个 TDengine 高可用系统，无论是 vnode 还是 mnode，都必须配置多个副本。
:::
## 负载均衡
有三种情况，将触发负载均衡，而且都无需人工干预。
当一个新数据节点添加进集群时，系统将自动触发负载均衡，一些节点上的数据将被自动转移到新数据节点上，无需任何人工干预。
当一个数据节点从集群中移除时，系统将自动把该数据节点上的数据转移到其他数据节点，无需任何人工干预。
如果一个数据节点过热（数据量过大），系统将自动进行负载均衡，将该数据节点的一些 vnode 自动挪到其他节点。
当上述三种情况发生时，系统将启动各个数据节点的负载计算，从而决定如何挪动。
:::tip
负载均衡由参数 balance 控制，它决定是否启动自动负载均衡，0 表示禁用，1 表示启用自动负载均衡。
:::
## 数据节点离线处理
如果一个数据节点离线，TDengine 集群将自动检测到。有如下两种情况：
该数据节点离线超过一定时间（taos.cfg 里配置参数 offlineThreshold 控制时长），系统将自动把该数据节点删除，产生系统报警信息，触发负载均衡流程。如果该被删除的数据节点重新上线时，它将无法加入集群，需要系统管理员重新将其添加进集群才会开始工作。
离线后，在 offlineThreshold 的时长内重新上线，系统将自动启动数据恢复流程，等数据完全恢复后，该节点将开始正常工作。
:::note
如果一个虚拟节点组（包括 mnode 组）里所归属的每个数据节点都处于离线或 unsynced 状态，必须等该虚拟节点组里的所有数据节点都上线、都能交换状态信息后，才能选出 Master，该虚拟节点组才能对外提供服务。比如整个集群有 3 个数据节点，副本数为 3，如果 3 个数据节点都宕机，然后 2 个数据节点重启，是无法工作的，只有等 3 个数据节点都重启成功，才能对外服务。
:::
## Arbitrator 的使用
如果副本数为偶数，当一个 vnode group 里一半或超过一半的 vnode 不工作时，是无法从中选出 master 的。同理，一半或超过一半的 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。
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。
Arbitrator 的执行程序名为 tarbitrator。该程序对系统资源几乎没有要求，只需要保证有网络连接，找任何一台 Linux 服务器运行它即可。以下简要描述安装配置的步骤：
请点击 安装包下载，在 TDengine Arbitrator Linux 一节中，选择合适的版本下载并安装。
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。
修改每个 taosd 实例的配置文件，在 taos.cfg 里将参数 arbitrator 设置为 tarbitrator 程序所对应的 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。）
在配置文件中配置了的 Arbitrator，会出现在 SHOW DNODES 指令的返回结果中，对应的 role 列的值会是“arb”。
查看集群 Arbitrator 的状态【2.0.14.0 以后支持】
```sql
SHOW DNODES;
```

## Mnode 的高可用性
TDengine 集群是由 mnode（taosd 的一个模块，管理节点）负责管理的，为保证 mnode 的高可用，可以配置多个 mnode 副本，在集群启动时只有一个 mnode，用户可以通过 `create mnode` 来增加新的 mnode。用户可以通过该命令自主决定哪几个 dnode 会承担 mnode 的角色。为保证元数据的强一致性，在有多个 mnode 时，mnode 副本之间是通过同步的方式进行数据复制的。
一个集群有多个数据节点 dnode，但一个 dnode 至多运行一个 mnode 实例。用户可通过 CLI 程序 taos，在 TDengine 的 console 里，执行如下命令：
```sql
SHOW MNODES;
```
来查看 mnode 列表，该列表将列出 mnode 所处的 dnode 的 End Point 和角色（leader, follower, candidate, offline）。当集群中第一个数据节点启动时，该数据节点一定会运行一个 mnode 实例，否则该数据节点 dnode 无法正常工作，因为一个系统是必须有至少一个 mnode 的。
在 TDengine 3.0 及以后的版本中，数据同步采用 RAFT 协议，所以 mnode 的数量应该被设置为 1 个或者 3 个。

title: 负载均衡
---
TDengine 中的负载均衡主要指对时序数据的处理的负载均衡。TDengine 采用 Hash 一致性算法将一个数据库中的所有表和子表的数据均衡分散在属于该数据库的所有 vgroup 中，每张表或子表只能由一个 vgroup 处理，一个 vgroup 可能负责处理多个表或子表。
创建数据库时可以指定其中的 vgroup 的数量：
```sql
create database db0 vgroups 100;
```
如何指定合适的 vgroup 的数量，这取决于系统资源。假定系统中只计划建立一个数据库，则 vgroup 数量由集群中所有 dnode 所能使用的资源决定。原则上可用的 CPU 和 Memory 越多，可建立的 vgroup 也越多。但也要考虑到磁盘性能，过多的 vgroup 在磁盘性能达到上限后反而会拖累整个系统的性能。假如系统中会建立多个数据库，则多个数据库的 vgroup 之和取决于系统中可用资源的数量。要综合考虑多个数据库之间表的数量、写入频率、数据量等多个因素在多个数据库之间分配 vgroup。实际中建议首先根据系统资源配置选择一个初始的 vgroup 数量，比如 CPU 总核数的 2 倍，以此为起点通过测试找到最佳的 vgroup 数量配置，此为系统中的 vgroup 总数。如果有多个数据库的话，再根据各个数据库的表数和数据量对 vgroup 进行分配。
此外，对于任意数据库的 vgroup，TDengine 都是尽可能将其均衡分散在多个 dnode 上。在多副本情况下（replica 3），这种均衡分布尤其复杂，TDengine 的分布策略会尽量避免任意一个 dnode 成为写入的瓶颈。
通过以上措施可以最大限度地在整个 TDengine 集群中实现负载均衡，负载均衡也能反过来提升系统总的数据处理能力。
在初始的负载均衡建立起来之后，如果由于删库、删表等动作，特别是删库动作会导致属于它的 vnode 都被删除，这有可能会造成一定程度的负载失衡，在后续版本中会提供重新平衡的方法。但如果有新的数据库建立，TDengine 也能够一定程度自我再平衡而无须人工干预。

sidebar_label: 按窗口切分聚合
title: 按窗口切分聚合
sidebar_label: 时序数据特色查询
title: 时序数据特色查询
---
TDengine 是专为时序数据而研发的大数据平台，存储和计算都针对时序数据的特定进行了量身定制，在支持标准 SQL 的基础之上，还提供了一系列贴合时序业务场景的特色查询语法，极大的方便时序场景的应用开发。
TDengine 支持按时间段窗口切分方式进行聚合结果查询，比如温度传感器每秒采集一次数据，但需查询每隔 10 分钟的温度平均值。这种场景下可以使用窗口子句来获得需要的查询结果。
窗口子句用于针对查询的数据集合进行按照窗口切分成为查询子集并进行聚合，窗口包含时间窗口（time window）、状态窗口（status window）、会话窗口（session window）三种窗口。其中时间窗口又可划分为滑动时间窗口和翻转时间窗口。
TDengine 提供的特色查询包括标签切分查询和窗口切分查询。
## 时间窗口
## 标签切分查询
超级表查询中，当需要针对标签进行数据切分然后在切分出的数据空间内再进行一系列的计算时使用标签切分子句，标签切分的语句如下：
```sql
PARTITION BY tag_list
```
其中 `tag_list` 是标签列的列表，还可以包括 tbname 伪列。
TDengine 按如下方式处理标签切分子句：
标签切分子句位于 `WHERE` 子句之后，且不能和 `JOIN` 子句一起使用。
标签切分子句将超级表数据按指定的标签组合进行切分，然后对每个切分的分片进行指定的计算。计算由之后的子句定义（窗口子句、`GROUP BY` 子句或`SELECT` 子句）。
标签切分子句可以和窗口切分子句（或 `GROUP BY` 子句）一起使用，此时后面的子句作用在每个切分的分片上。例如，下面的示例将数据按标签 `location` 进行分组，并对每个组按 10 分钟进行降采样，取其最大值。
```sql
select max(current) from meters partition by location interval(10m)
```
## 窗口切分查询
TDengine 支持按时间段窗口切分方式进行聚合结果查询，比如温度传感器每秒采集一次数据，但需查询每隔 10 分钟的温度平均值。这种场景下可以使用窗口子句来获得需要的查询结果。窗口子句用于针对查询的数据集合按照窗口切分成为查询子集并进行聚合，窗口包含时间窗口（time window）、状态窗口（status window）、会话窗口（session window）三种窗口。其中时间窗口又可划分为滑动时间窗口和翻转时间窗口。窗口切分查询语法如下：
```sql
SELECT function_list FROM tb_name
[WHERE where_condition]
[SESSION(ts_col, tol_val)]
[STATE_WINDOW(col)]
[INTERVAL(interval [, offset]) [SLIDING sliding]]
[FILL({NONE | VALUE | PREV | NULL | LINEAR | NEXT})]
```
在上述语法中的具体限制如下
### 窗口切分查询中使用函数的限制
- 在聚合查询中，function_list 位置允许使用聚合和选择函数，并要求每个函数仅输出单个结果（例如：COUNT、AVG、SUM、STDDEV、LEASTSQUARES、PERCENTILE、MIN、MAX、FIRST、LAST），而不能使用具有多行输出结果的函数（例如：DIFF 以及四则运算）。
- 此外 LAST_ROW 查询也不能与窗口聚合同时出现。
- 标量函数（如：CEIL/FLOOR 等）也不能使用在窗口聚合查询中。
### 窗口子句的规则
- 窗口子句位于标签切分子句之后，GROUP BY 子句之前，且不可以和 GROUP BY 子句一起使用。
- 窗口子句将数据按窗口进行切分，对每个窗口进行 SELECT 列表中的表达式的计算，SELECT 列表中的表达式只能包含：
- 常量。
- 聚集函数。
- 包含上面表达式的表达式。
- 窗口子句不可以和 GROUP BY 子句一起使用。
- WHERE 语句可以指定查询的起止时间和其他过滤条件。
### FILL 子句
FILL 语句指定某一窗口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：
1. 不进行填充：NONE（默认填充模式）。
2. 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)。这里需要注意，最终填充的值受由相应列的类型决定，如 FILL(VALUE, 1.23)，相应列为 INT 类型，则填充值为 1。
3. PREV 填充：使用前一个非 NULL 值填充数据。例如：FILL(PREV)。
4. NULL 填充：使用 NULL 填充数据。例如：FILL(NULL)。
5. LINEAR 填充：根据前后距离最近的非 NULL 值做线性插值填充。例如：FILL(LINEAR)。
6. NEXT 填充：使用下一个非 NULL 值填充数据。例如：FILL(NEXT)。
:::info
1. 使用 FILL 语句的时候可能生成大量的填充输出，务必指定查询的时间区间。针对每次查询，系统可返回不超过 1 千万条具有插值的结果。
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。
:::
### 时间窗口
时间窗口又可分为滑动时间窗口和翻转时间窗口。
INTERVAL 子句用于产生相等时间周期的窗口，SLIDING 用以指定窗口向前滑动的时间。每次执行的查询是一个时间窗口，时间窗口随着时间流动向前滑动。在定义连续查询的时候需要指定时间窗口（time window ）大小和每次前向增量时间（forward sliding times）。如图，[t0s, t0e] ，[t1s , t1e]， [t2s, t2e] 是分别是执行三次连续查询的时间窗口范围，窗口的前向滑动的时间范围 sliding time 标识 。查询过滤、聚合等操作按照每个时间窗口为独立的单位执行。当 SLIDING 与 INTERVAL 相等的时候，滑动窗口即为翻转窗口。
......@@ -25,11 +97,13 @@ SLIDING 的向前滑动的时间不能超过一个窗口的时间范围。以下
SELECT COUNT(*) FROM temp_tb_1 INTERVAL(1m) SLIDING(2m);
```
当 SLIDING 与 INTERVAL 取值相等的时候，滑动窗口即为翻转窗口。
_ 聚合时间段的窗口宽度由关键词 INTERVAL 指定，最短时间间隔 10 毫秒（10a）；并且支持偏移 offset（偏移必须小于间隔），也即时间窗口划分与“UTC 时刻 0”相比的偏移量。SLIDING 语句用于指定聚合时间段的前向增量，也即每次窗口向前滑动的时长。
_ 从 2.1.5.0 版本开始，INTERVAL 语句允许的最短时间间隔调整为 1 微秒（1u），当然如果所查询的 DATABASE 的时间精度设置为毫秒级，那么允许的最短时间间隔为 1 毫秒（1a）。 \* **注意**：用到 INTERVAL 语句时，除非极特殊的情况，都要求把客户端和服务端的 taos.cfg 配置文件中的 timezone 参数配置为相同的取值，以避免时间处理函数频繁进行跨时区转换而导致的严重性能影响。

### 状态窗口
使用整数（布尔值）或字符串来标识产生记录时候设备的状态量。产生的记录如果具有相同的状态量数值则归属于同一个状态窗口，数值改变后该窗口关闭。如下图所示，根据状态量确定的状态窗口分别是[2019-04-28 14:22:07，2019-04-28 14:22:10]和[2019-04-28 14:22:11，2019-04-28 14:22:12]两个。（状态窗口暂不支持对超级表使用）

转义后的表（列）名同样受到长度限制要求，且长度计算的时候不计算转义符。使用转义字符以后，不再对转义字符中的内容进行大小写统一。
例如：\`aBc\` 和 \`abc\` 是不同的表（列）名，但是 abc 和 aBc 是相同的表（列）名。
需要注意的是转义字符中的内容必须是可打印字符。
支持转义符的功能从 2.3.0.1 版本开始。
## 密码合法字符集
`[a-zA-Z0-9!?$%^&*()_–+={[}]:;@~#|<,>.?/]`
去掉了 `` ‘“`\ `` (单双引号、撇号、反斜杠、空格)
- 数据库名：不能包含“.”以及特殊字符，不能超过 32 个字符
- 表名：不能包含“.”以及特殊字符，与所属数据库名一起，不能超过 192 个字节 ，每行数据最大长度 48KB
- 表的列名：不能包含特殊字符，不能超过 64 个字节
- 数据库名、表名、列名，都不能以数字开头，合法的可用字符集是“英文字符、数字和下划线”
- 表的列数：不能超过 1024 列，最少需要 2 列，第一列必须是时间戳（从 2.1.7.0 版本开始，改为最多支持 4096 列）
- 记录的最大长度：包括时间戳 8 字节，不能超过 48KB（每个 BINARY/NCHAR 类型的列还会额外占用 2 个 字节 的存储位置）
- 单条 SQL 语句默认最大字符串长度：1048576 字节，但可通过系统配置参数 maxSQLLength 修改，取值范围 65480 ~ 1048576 字节
- 数据库副本数：不能超过 3
- 用户名：不能超过 23 个 字节
- 用户密码：不能超过 15 个 字节
- 标签(Tags)数量：不能超过 128 个，可以 0 个
- 标签的总长度：不能超过 16KB
- 记录条数：仅受存储空间限制
- 表的个数：仅受节点个数限制
- 库的个数：仅受节点个数限制
- 单个库上虚拟节点个数：不能超过 64 个
- 库的数目，超级表的数目、表的数目，系统不做限制，仅受系统资源限制
- SELECT 语句的查询结果，最多允许返回 1024 列（语句中的函数调用可能也会占用一些列空间），超限时需要显式指定较少的返回数据列，以避免语句执行报错。（从 2.1.7.0 版本开始，改为最多允许 4096 列）
## 保留关键字
目前 TDengine 有将近 200 个内部保留关键字，这些关键字无论大小写均不可以用作库名、表名、STable 名、数据列名及标签列名等。这些关键字列表如下：

- batchfetch: true：在执行查询时批量拉取结果集；false：逐行拉取结果集。默认值为：false。逐行拉取结果集使用 HTTP 方式进行数据传输。从 taos-jdbcdriver-2.0.38 和 TDengine 2.4.0.12 版本开始，JDBC REST 连接增加批量拉取数据功能。taos-jdbcdriver 与 TDengine 之间通过 WebSocket 连接进行数据传输。相较于 HTTP，WebSocket 可以使 JDBC REST 连接支持大数据量查询，并提升查询性能。
- charset: 当开启批量拉取数据时，指定解析字符串数据的字符集。
- batchErrorIgnore：true：在执行 Statement 的 executeBatch 时，如果中间有一条 SQL 执行失败，继续执行下面的 SQL 了。false：不再执行失败 SQL 后的任何语句。默认值为：false。
- httpConnectTimeout: 连接超时时间，单位 ms， 默认值为 5000。
- httpSocketTimeout: socket 超时时间，单位 ms，默认值为 5000。仅在 batchfetch 设置为 false 时生效。
- messageWaitTimeout: 消息超时时间, 单位 ms， 默认值为 3000。 仅在 batchfetch 设置为 true 时生效。
