# Customize file classifications. #
# Results from files under any classifier will be excluded from LGTM #
# statistics. #
##########################################################################################
##########################################################################################
# Use the `path_classifiers` block to define changes to the default classification of #
# files. #
##########################################################################################
path_classifiers:
# docs:
# Identify the top-level file called `generate_javadoc.py` as documentation-related.
test:
# Override LGTM's default classification of test files by excluding all files.
- exclude: /
# Classify all files in the top-level directories tests/ and testsuites/ as test code.
- tests
# - testsuites
# Classify all files with suffix `.test` as test code.
# Note: use only forward slash / as a path separator.
# Use ** to indicate an arbitrary parent path.
# Use * to indicate any sequence of characters excluding /.
# Always enclose the expression in double quotes if it includes *.
# - "**/*.test"
# Refine the classifications above by excluding files in test/util/.
# - exclude: test/util
# The default behavior is to tag all files created during the
# build as `generated`. Results are hidden for generated code. You can tag
# further files as being generated by adding them to the `generated` section.
generated:
# Exclude all `*.c` files under the `ui/` directory from classification as
# generated code.
# - exclude: ui/**/*.c
# By default, all files not checked into the repository are considered to be
# 'generated'.
# The default behavior is to tag library code as `library`. Results are hidden
# for library code. You can tag further files as being library code by adding them
# to the `library` section.
library:
- exclude: deps/
# The default behavior is to tag template files as `template`. Results are hidden
# for template files. You can tag further files as being template files by adding
# them to the `template` section.
template:
#- exclude: path/to/template/code/**/*.c
# Define your own category, for example: 'some_custom_category'.
some_custom_category:
# Classify all files in the top-level directory tools/ (or the top-level file
# called tools).
# - tools
#########################################################################################
# Use the `queries` block to change the default display of query results. #
#########################################################################################
# queries:
# Start by hiding the results of all queries.
# - exclude: "*"
# Then include all queries tagged 'security' and 'correctness', and with a severity of
# 'error'.
# - include:
# tags:
# - "security"
# - "correctness"
# severity: "error"
# Specifically hide the results of two queries.
# - exclude: cpp/use-of-goto
# - exclude: java/equals-on-unrelated-types
# Refine by including the `java/command-line-injection` query.
# - include: java/command-line-injection
#########################################################################################
# Define changes to the default code extraction process. #
# Each block configures the extraction of a single language, and modifies actions in a #
# named step. Every named step includes automatic default actions, #
# except for the 'prepare' step. The steps are performed in the following sequence: #
# prepare #
# after_prepare #
# configure (C/C++ only) #
# python_setup (Python only) #
# before_index #

## Get the source codes
- github:
First of all, you may clone the source codes from github:
```bash
git clone https://github.com/taosdata/TDengine.git
cd TDengine
```
The connectors for go & grafana have been moved to separated repositories,
so you should run this command in the TDengine directory to install them:
```bash
git submodule update --init --recursive
```

具体的查询语法请看<a href="https://www.taosdata.com/cn/documentation20/taos-sql/">TAOS SQL </a>。
## 多表聚合查询
物联网场景中，往往同一个类型的数据采集点有多个。TDengine采用超级表(STable)的概念来描述某一个类型的数据采集点，一张普通的表来描述一个具体的数据采集点。同时TDengine使用标签来描述数据采集点的静态属性，一个具体的数据采集点有具体的标签值。通过指定标签的过滤条件，TDengine提供了一高效的方法将超级表(某一类型的数据采集点)所属的子表进行聚合查询。对普通表的聚合函数以及绝大部分操作都适用于超级表，语法完全一样。
TDengine对每个数据采集点单独建表，但在实际应用中经常需要对不同的采集点数据进行聚合。为高效的进行聚合操作，TDengine引入超级表（STable）的概念。超级表用来代表一特定类型的数据采集点，它是包含多张表的表集合，集合里每张表的模式（schema）完全一致，但每张表都带有自己的静态标签，标签可以多个，可以随时增加、删除和修改。
应用可通过指定标签的过滤条件，对一个STable下的全部或部分表进行聚合或统计操作，这样大大简化应用的开发。其具体流程如下图所示：
<center> <img src="../assets/stable.png"> </center>
<center> 多表聚合查询原理图 </center>
1：应用将一个查询条件发往系统；2: taosc将超级表的名字发往 Meta Node（管理节点)；3：管理节点将超级表所拥有的 vnode 列表发回 taosc；4：taosc将计算的请求连同标签过滤条件发往这些vnode对应的多个数据节点；5：每个vnode先在内存里查找出自己节点里符合标签过滤条件的表的集合，然后扫描存储的时序数据，完成相应的聚合计算，将结果返回给taosc；6：taosc将多个数据节点返回的结果做最后的聚合，将其返回给应用。
由于TDengine在vnode内将标签数据与时序数据分离存储，通过先在内存里过滤标签数据，将需要扫描的数据集大幅减少，大幅提升聚合计算速度。同时，由于数据分布在多个vnode/dnode，聚合计算操作在多个vnode里并发进行，又进一步提升了聚合的速度。
对普通表的聚合函数以及绝大部分操作都适用于超级表，语法完全一样，细节请看 TAOS SQL。
比如：在TAOS Shell，查找所有智能电表采集的电压平均值，并按照location分组
**示例1**：在TAOS Shell，查找北京所有智能电表采集的电压平均值，并按照location分组
```mysql
taos> SELECT AVG(voltage) FROM meters GROUP BY location;

## 降采样查询、插值
物联网场景里，经常需要通过降采样（down sampling）将采集的数据按时间段进行聚合。TDengine 提供了一个简便的关键词 interval 让按照时间窗口的查询操作变得极为简单。比如，将智能电表 d1001 采集的电流值每10秒钟求和

TDengine 分布式架构的逻辑结构图如下：
<center> <img src="../assets/structure.png"> </center>
<center> 图 1 TDengine架构示意图 </center>
一个完整的 TDengine 系统是运行在一到多个物理节点上的，逻辑上，它包含数据节点(dnode)、TDengine客户端(taosc)以及应用(app)。系统中存在一到多个数据节点，这些数据节点组成一个集群(cluster)。应用通过taosc的API与TDengine集群进行互动。下面对每个逻辑单元进行简要介绍。

**物理节点(pnode):** pnode是一独立运行、拥有自己的计算、存储和网络能力的计算机，可以是安装有OS的物理机、虚拟机或容器。物理节点由其配置的 FQDN(Fully Qualified Domain Name)来标识。TDengine完全依赖FQDN来进行网络通讯，如果不了解FQDN，请看博文《[一篇文章说清楚TDengine的FQDN](https://www.taosdata.com/blog/2020/09/11/1824.html)》。
**物理节点(pnode):** pnode是一独立运行、拥有自己的计算、存储和网络能力的计算机，可以是安装有OS的物理机、虚拟机或Docker容器。物理节点由其配置的 FQDN(Fully Qualified Domain Name)来标识。TDengine完全依赖FQDN来进行网络通讯，如果不了解FQDN，请看博文《[一篇文章说清楚TDengine的FQDN](https://www.taosdata.com/blog/2020/09/11/1824.html)》。
**数据节点(dnode):** dnode 是 TDengine 服务器侧执行代码 taosd 在物理节点上的一个运行实例，一个工作的系统必须有至少一个数据节点。dnode包含零到多个逻辑的虚拟节点(VNODE)，零或者至多一个逻辑的管理节点(mnode)。dnode在系统中的唯一标识由实例的End Point (EP )决定。EP是dnode所在物理节点的FQDN (Fully Qualified Domain Name)和系统所配置的网络端口号(Port)的组合。通过配置不同的端口，一个物理节点(一台物理机、虚拟机或容器）可以运行多个实例，或有多个数据节点。
**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。
**TAOSC:** taosc是TDengine给应用提供的驱动程序(driver)，负责处理应用与集群的接口交互，内嵌于JDBC、ODBC driver中，或者C、Python、Go语言连接库里。应用都是通过taosc而不是直接连接集群中的数据节点与整个集群进行交互的。这个模块负责获取并缓存元数据；将插入、查询等请求转发到正确的数据节点；在把结果返回给应用时，还需要负责最后一级的聚合、排序、过滤等操作。对于JDBC, ODBC, C/C++接口而言，这个模块是在应用所处的物理节点上运行，但消耗的资源很小。同时，为支持全分布式的RESTful接口，taosc在TDengine集群的每个dnode上都有一运行实例。

### 节点之间的通讯
**通讯方式：**TDengine系统的各个节点之间的通讯是通过TCP/UDP进行的。因为考虑到物联网场景，数据写入的包一般不大，因此TDengine 除采用TCP做传输之外，还采用UDP方式，因为UDP 更加高效，而且不受连接数的限制。TDengine实现了自己的超时、重传、确认等机制，以确保UDP的可靠传输。对于数据量不到15K的数据包，采取UDP的方式进行传输，超过15K的，或者是查询类的操作，自动采取TCP的方式进行传输。同时，TDengine根据配置和数据包，会自动对数据进行压缩/解压缩，数字签名/认证等处理。对于数据节点之间的数据复制，只采用TCP方式进行数据传输。

**FQDN配置**：一个数据节点有一个或多个FQDN，可以在系统配置文件taos.cfg通过参数“fqdn"进行指定，如果没有指定，系统将自动获取FQDN。如果节点没有配置FQDN，可以直接将该节点的配置参数fqdn设置为它的IP地址。但不建议使用IP，因为IP地址可变，一旦变化，将让集群无法正常工作。一个数据节点的EP(End Point)由FQDN + Port组成。采用FQDN，需要保证DNS服务正常工作，或者在节点以及应用所在的节点配置好hosts文件。

**端口配置：**一个数据节点对外的端口由TDengine的系统配置参数serverPort决定，对集群内部通讯的端口是serverPort+5。集群内数据节点之间的数据复制操作还占有一个TCP端口，是serverPort+10. 为支持多线程高效的处理UDP数据，每个对内和对外的UDP链接，都需要占用5个连续的端口。因此一个数据节点总的端口范围为serverPort到serverPort + 10，总共11个TCP/UDP端口。使用时，需要确保防火墙将这些端口打开。每个数据节点可以配置不同的serverPort。

**集群对外链接:** TDengine集群可以容纳单个、多个甚至几千个数据节点。应用只需要向集群中任何一个数据节点发起连接即可，链接需要提供的网络参数是一数据节点的End Point(FQDN加配置的端口号）。通过命令行CLI启动应用taos时，可以通过选项-h来指定数据节点的FQDN, -P来指定其配置的端口号，如果端口不配置，将采用TDengine的系统配置参数serverPort。

**集群内部通讯**: 各个数据节点之间通过TCP/UDP进行链接。一个数据节点启动时，将获取mnode所在的dnode的EP信息，然后与系统中的mnode建立起链接，交换信息。获取mnode的EP信息有三步，1：检查mnodeEpList文件是否存在，如果不存在或不能正常打开获得mnode EP信息，进入第二步；2：检查系统配置文件taos.cfg, 获取mnode EP配置参数first, second，如果不存在或者taos.cfg里没有这两个配置参数，或无效，进入第三步；3：将自己的EP设为mnode EP, 并独立运行起来。获取mnode EP列表后，数据节点发起链接，如果链接成功，则成功加入进工作的集群，如果不成功，则尝试mnode EP列表中的下一个。如果都尝试了，但链接都仍然失败，则休眠几秒后，再进行尝试。

**MNODE的选择:** TDengine逻辑上有管理节点，但没有单独的执行代码，服务器侧只有一套执行代码taosd。那么哪个数据节点会是管理节点呢？这是系统自动决定的，无需任何人工干预。原则如下：一个数据节点启动时，会检查自己的End Point, 并与获取的mnode EP List进行比对，如果在其中，该数据节点认为自己应该启动mnode模块，成为mnode。如果自己的EP不在mnode EP List里，则不启动mnode模块。在系统的运行过程中，由于负载均衡、宕机等原因，mnode有可能迁移至新的dnode，但一切都是透明的，无需人工干预，配置参数的修改，是mnode自己根据资源做出的决定。
**新数据节点的加入**：系统有了一个数据节点后，就已经成为一个工作的系统。添加新的节点进集群时，有两个步骤，第一步：使用TDengine CLI链接到现有工作的数据节点，然后用命令”create dnode"将新的数据节点的End Point添加进去; 第二步：在新的数据节点的系统配置参数文件taos.cfg里，将first, second参数设置为现有集群中任意两个数据节点的EP即可。具体添加的详细步骤请见详细的用户手册。这样就把集群一步一步的建立起来。

**重定向**：无论是dnode还是taosc，最先都是要发起与mnode的链接，但mnode是系统自动创建并维护的，因此对于用户来说，并不知道哪个dnode在运行mnode。TDengine只要求向系统中任何一个工作的dnode发起链接即可。因为任何一个正在运行的dnode，都维护有目前运行的mnode EP List。当收到一个来自新启动的dnode或taosc的链接请求，如果自己不是mnode，则将mnode EP List回复给对方，taosc或新启动的dnode收到这个list, 就重新尝试建立链接。当mnode EP List发生改变，通过节点之间的消息交互，各个数据节点就很快获取最新列表，并通知taosc。

给定days与keep两个参数，一个vnode总的数据文件数为：keep/days。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，一但设置后，不可修改。

## 数据查询
TDengine提供了多种多样针对表和超级表的查询处理功能，除了常规的聚合查询之外，还提供针对时序数据的窗口查询、统计聚合等功能。TDengine的查询处理需要客户端、vnode, mnode节点协同完成。
@ -276,24 +279,31 @@ SQL语句的解析和校验工作在客户端完成。解析SQL语句并生成
在TDengine中引入关键词interval来进行时间轴上固定长度时间窗口的切分，并按照时间窗口对数据进行聚合，对窗口范围内的数据按需进行聚合。例如：
```mysql
select count(*) from d1001 interval(1h)；
select count(*) from d1001 interval(1h);
```
针对d1001设备采集的数据，按照1小时的时间窗口返回每小时存储的记录数量。
在需要连续获得查询结果的应用场景下，如果给定的时间区间存在数据缺失，会导致该区间数据结果也丢失。TDengine提供策略针对时间轴聚合计算的结果进行插值，通过使用关键词Fill就能够对时间轴聚合结果进行插值。例如：
```mysql
select count(*) from d1001 interval(1h) fill(prev)；
select count(*) from d1001 interval(1h) fill(prev);
```
针对d1001设备采集数据统计每小时记录数，如果某一个小时不存在数据，这返回之前一个小时的统计数据。TDengine提供前向插值(prev)、线性插值(linear)、NULL值填充(NULL)、特定值填充(value)。
### 多表聚合查询
多表聚合查询与单表查询的整体流程相同，但是存在如下的差异：
TDengine对每个数据采集点单独建表，但在实际应用中经常需要对不同的采集点数据进行聚合。为高效的进行聚合操作，TDengine引入超级表（STable）的概念。超级表用来代表一特定类型的数据采集点，它是包含多张表的表集合，集合里每张表的模式（schema）完全一致，但每张表都带有自己的静态标签，标签可以多个，可以随时增加、删除和修改。 应用可通过指定标签的过滤条件，对一个STable下的全部或部分表进行聚合或统计操作，这样大大简化应用的开发。其具体流程如下图所示：
<center> <img src="../assets/multi_tables.png"> </center>
- 由于多表可能分布在不同的节点(dnode)，因此多表的聚合查询需要首先获得表所在的全部数据节点的信息，并且同时向相关的dnode发出查询请求。
- 每个vnode的计算获得的中间结果(partial results)需要进行第二阶段的聚合才能形成最终结果，第二阶段的聚合过程在客户端完成。
- 由于表标签信息存储在vnode中，因此针对标签信息的查询也需要vnode完成。客户端将标签的过滤表达式封装在查询请求结构体中发送给vnode，由vnode的查询执行线程从中抽取出标签查询条件，然后执行查询。标签查询与过滤是在针对表的查询之前完成。标签查询完成以后，将符合条件的表纳入到接下来的查询处理流程中。
<center> 图 5 多表聚合查询原理图 </center>
1：应用将一个查询条件发往系统；
2: taosc将超级表的名字发往 Meta Node（管理节点)；
3：管理节点将超级表所拥有的 vnode 列表发回 taosc；
4：taosc将计算的请求连同标签过滤条件发往这些vnode对应的多个数据节点；
5：每个vnode先在内存里查找出自己节点里符合标签过滤条件的表的集合，然后扫描存储的时序数据，完成相应的聚合计算，将结果返回给taosc；
6：taosc将多个数据节点返回的结果做最后的聚合，将其返回给应用。
由于TDengine在vnode内将标签数据与时序数据分离存储，通过在内存里过滤标签数据，先找到需要参与聚合操作的表的集合，将需要扫描的数据集大幅减少，大幅提升聚合计算速度。同时，由于数据分布在多个vnode/dnode，聚合计算操作在多个vnode里并发进行，又进一步提升了聚合的速度。 对普通表的聚合函数以及绝大部分操作都适用于超级表，语法完全一样，细节请看 TAOS SQL。
### 预计算
为有效提升查询处理的性能，针对物联网数据的不可更改的特点，在数据块头部记录该数据块中存储数据的统计信息：包括最大值、最小值、和。我们称之为预计算单元。如果查询处理涉及整个数据块的全部数据，直接使用预计算结果，完全不需要读取数据块的内容。由于预计算数据量远小于磁盘上存储的数据块数据的大小，对于磁盘IO为瓶颈的查询处理，使用预计算结果可以极大地减小读取IO压力，加速查询处理的流程。预计算机制与Postgre SQL的索引BRIN（block range index）有异曲同工之妙。

如果一个unsynced节点要发起数据恢复流程，它与Master将建立起专有的TCP链接(syncFd)。数据恢复完成后，该链接会被关闭。而且为限制资源的使用，系统只容许一定数量(配置参数tsMaxSyncNum)的数据恢复的socket存在。如果超过这个数字，系统会将新的数据恢复请求延后处理。

任意一个节点，无论有多少虚拟节点，都会启动而且只会启动一个TCP server, 来接受来自其他虚拟节点的上述两类TCP的链接请求。当TCP socket建立起来，客户端侧发送的消息体里会带有vgId（全局唯一的vgroup ID), TCP 服务器侧会检查该vgId是否已经在该节点启动运行。如果已经启动运行，就接受其请求。如果不存在，就直接将链接请求关闭。在TDengine代码里，mnode group的vgId设置为1。

如果一个虚拟节点(vnode A)检测到与同一虚拟节点组内另外一虚拟节点（vnode B）的链接中断，vnode A将立即把vnode B的role设置为offline。无论是接收到另外一虚拟节点发来的status消息，还是检测与另外一虚拟节点的链接中断，该虚拟节点都将进入状态处理流程。状态处理流程的规则如下：

对于回复确认，sync模块提供的是异步回调函数，因此APP在调用syncForwardToPeer之后，无需等待，可以处理下一个操作。在Master与Slave的TCP链接管道里，可能有多个Forward消息，这些消息是严格按照应用提供的顺序排好的。对于Forward Response也是一样，TCP管道里存在多个，但都是排序好的。这个顺序，SYNC模块并没有做特别的事情，是由APP单线程顺序写来保证的(TDengine里每个vnode的写数据，都是单线程）。

2. 如果getWalInfo返回值大于0，表示该文件还不是最后一个WAL，因此master调用sendfile一下把该文件发送给vnode B
3. 如果getWalInfo返回时为0，表示该文件是最后一个WAL，因为文件可能还处于写的状态中，sync模块要根据WAL Head的定义逐条读出记录，然后发往vnode B。

因为写入失败，客户端会重新写入数据。但对于TDengine而言，是OK的。因为时序数据都是有时间戳的，时间戳相同的数据更新操作，第一次会执行，但第二次会自动扔掉。对于Meta Data(增加、删除库、表等等）的操作，也是OK的。一张表、库已经被创建或删除，再创建或删除，不会被执行的。
在TDengine的设计里，虚拟节点与虚拟节点之间，是一个TCP链接，是一个pipeline，数据块一个接一个按顺序在这个pipeline里等待处理。一旦某个数据块的处理失败，这个链接会被重置，后续的数据块的处理都会失败。因此不会存在Pipeline里一个数据块更新失败，但下一个数据块成功的可能。

## Split Brain的问题
选举流程中，有个强制要求，那就是一定有超过半数的虚拟节点在线。但是如果replication正好是偶数，这个时候，完全可能存在splt brain问题。
为解决这个问题，TDengine提供Arbitrator的解决方法。Arbitrator是一个节点，它的任务就是接受任何虚拟节点的链接请求，并保持它。

在启动复制模块实例时，在配置参数中，应用可以提供Arbitrator的IP地址。如果是奇数个副本，复制模块不会与这个arbitrator去建立链接，但如果是偶数个副本，就会主动去建立链接。

各个dnode通过信息交换，保存有mnode各个副本的End Point列表，并向其中的master节点定时（间隔由系统配置参数statusInterval控制）发送status消息，消息体里包含该dnode的CPU、内存、剩余存储空间、vnode个数，以及各个vnode的状态(存储空间、原始数据大小、记录条数、角色等）。这样mnode就了解整个系统的资源情况，如果用户创建新的表，就可以决定需要在哪个dnode创建；如果增加或删除dnode, 或者监测到某dnode数据过热、或离线太长，就可以决定需要挪动那些vnode，以实现负载均衡。
