# 构建
TDengine 目前可以在 Linux、 Windows 等平台上安装和运行。任何 OS 的应用也可以选择 taosAdapter 的 RESTful 接口连接服务端 taosd。CPU 支持 X64/ARM64，后续会支持 MIPS64、Alpha64、ARM32、RISC-V 等 CPU 架构。
用户可根据需求选择通过源码、[容器](https://docs.taosdata.com/3.0/get-started/docker/)、[安装包](https://docs.taosdata.com/3.0/get-started/package/)或[Kubenetes](https://docs.taosdata.com/3.0/deployment/k8s/)来安装。本快速指南仅适用于通过源码安装。

TDengine 还提供一组辅助工具软件 taosTools，目前它包含 taosBenchmark（曾命名为 taosdemo）和 taosdump 两个软件。默认 TDengine 编译不包含 taosTools, 您可以在编译 TDengine 时使用`cmake .. -DBUILD_TOOLS=true` 来同时编译 taosTools。
为了构建TDengine, 请使用 [CMake](https://cmake.org/) 3.0.2 或者更高版本。

# What is TDengine？
TDengine is an open source, cloud native time-series database optimized for Internet of Things (IoT), Connected Cars, and Industrial IoT. It enables efficient, real-time data ingestion, processing, and monitoring of TB and even PB scale data per day, generated by billions of sensors and data collectors. TDengine differentiates itself from other TSDBs with the following advantages.:
TDengine is an open source, high performance , cloud native time-series database (Time-Series Database, TSDB).
TDengine can be optimized for Internet of Things (IoT), Connected Cars, and Industrial IoT, IT operation and maintenance, finance and other fields. In addition to the core time series database functions, TDengine also provides functions such as caching, data subscription, and streaming computing. It is a minimalist time series data processing platform that minimizes the complexity of system design and reduces R&D and operating costs. Compared with other time series databases, the main advantages of TDengine are as follows:
- High-Performance: TDengine is the only time-series database to solve the high cardinality issue to support billions of data collection points while out performing other time-series databases for data ingestion, querying and data compression.

# Building
At the moment, TDengine server supports running on Linux, Windows, and macOS systems. You can choose to [install from packages](https://www.tdengine.com/getting-started/#Install-from-Package) or build it from the source code. This quick guide is for installation from the source only.
We provide a few useful tools such as taosBenchmark (was named taosdemo) and taosdump. They were part of TDengine. By default, TDengine compiling does not include taosTools. You can use 'cmake .. -DBUILD_TOOLS=true' to make them be compiled with TDengine.

TDengine supports X64/ARM64 CPU , and it will support MIPS64, Alpha64, ARM32, RISC-V and other CPU architectures in the future.
You can choose to install through source code according to your needs, [container](https://docs.taosdata.com/get-started/docker/), [installation package](https://docs.taosdata.com/get-started/package/) or [Kubenetes](https://docs.taosdata.com/deployment/k8s/) to install.

title: 流式计算
---
在时序数据的处理中，经常要对原始数据进行清洗、预处理，再使用时序数据库进行长久的储存。用户通常需要在时序数据库之外再搭建 Kafka、Flink、Spark 等流计算处理引擎，增加了用户的开发成本和维护成本。
使用 TDengine 3.0 的流式计算引擎能够最大限度的减少对这些额外中间件的依赖，真正将数据的写入、预处理、长期存储、复杂分析、实时计算、实时报警触发等功能融为一体，并且，所有这些任务只需要使用 SQL 完成，极大降低了用户的学习成本、使用成本。
在时序数据的处理中，经常要对原始数据进行清洗、预处理，再使用时序数据库进行长久的储存。在传统的时序数据解决方案中，常常需要部署 Kafka、Flink 等流处理系统。而流处理系统的复杂性，带来了高昂的开发与运维成本。
TDengine 3.0 的流式计算引擎提供了实时处理写入的数据流的能力，使用 SQL 定义实时流变换，当数据被写入流的源表后，数据会被以定义的方式自动处理，并根据定义的触发模式向目的表推送结果。它提供了替代复杂流处理系统的轻量级解决方案，并能够在高吞吐的数据写入的情况下，提供毫秒级的计算结果延迟。
流式计算可以包含数据过滤，标量函数计算（含UDF），以及窗口聚合（支持滑动窗口、会话窗口与状态窗口），可以以超级表、子表、普通表为源表，写入到目的超级表。在创建流时，目的超级表将被自动创建，随后新插入的数据会被流定义的方式处理并写入其中，通过 partition by 子句，可以以表名或标签划分 partition，不同的 partition 将写入到目的超级表的不同子表。
TDengine 的流式计算能够支持分布在多个 vnode 中的超级表聚合；还能够处理乱序数据的写入：它提供了 watermark 机制以度量容忍数据乱序的程度，并提供了 ignore expired 配置项以决定乱序数据的处理策略——丢弃或者重新计算。

### 创建 DB 和原始数据表
首先准备数据，完成建库、建一张超级表和多张子表操作
```sql
drop database if exists stream_db;
create database stream_db;
DROP DATABASE IF EXISTS power;
CREATE DATABASE power;
USE power;
create stable stream_db.meters (ts timestamp, current float, voltage int) TAGS (location varchar(64), groupId int);
CREATE STABLE meters (ts timestamp, current float, voltage int, phase float) TAGS (location binary(64), groupId int);
create table stream_db.d1001 using stream_db.meters tags("beijing", 1);
create table stream_db.d1002 using stream_db.meters tags("guangzhou", 2);
create table stream_db.d1003 using stream_db.meters tags("shanghai", 3);
CREATE TABLE d1001 USING meters TAGS ("California.SanFrancisco", 2);
CREATE TABLE d1002 USING meters TAGS ("California.SanFrancisco", 3);
CREATE TABLE d1003 USING meters TAGS ("California.LosAngeles", 2);
CREATE TABLE d1004 USING meters TAGS ("California.LosAngeles", 3);
```
### 创建流
```sql
create stream stream1 into stream_db.stream1_output_stb as select _wstart as start, _wend as end, max(current) as max_current from stream_db.meters where voltage <= 220 and ts > now - 12h interval (1h);
create stream current_stream into current_stream_output_stb as select _wstart as start, _wend as end, max(current) as max_current from meters where voltage <= 220 interval (5s);
```
### 写入数据
```sql
insert into stream_db.d1001 values(now-14h, 10.3, 210);
insert into stream_db.d1001 values(now-13h, 13.5, 216);
insert into stream_db.d1001 values(now-12h, 12.5, 219);

## 示例二
某运营商平台要采集机房所有服务器的系统资源指标，包含 cpu、内存、网络延迟等，采集后需要对数据进行四舍五入运算，将地域和服务器名以下划线拼接，然后将结果按时间排序并以服务器名分组输出到新的数据表中。
依然以示例一中的数据为基础，我们已经采集到了每个智能电表的电流和电压数据，现在需要求出有功功率和无功功率，并将地域和电表名以符号 "." 拼接，然后以电表名称分组输出到新的数据表中。
### 创建 DB 和原始数据表
首先准备数据，完成建库、建一张超级表和多张子表操作
```sql
drop database if exists stream_db;
create database stream_db;
create stable stream_db.idc (ts timestamp, cpu float, mem float, latency float) TAGS (location varchar(64), groupId int);
create table stream_db.server01 using stream_db.idc tags("beijing", 1);
create table stream_db.server02 using stream_db.idc tags("shanghai", 2);
create table stream_db.server03 using stream_db.idc tags("beijing", 2);
create table stream_db.server04 using stream_db.idc tags("tianjin", 3);
create table stream_db.server05 using stream_db.idc tags("shanghai", 1);
```
参考示例一 [创建 DB 和原始数据表](#创建-db-和原始数据表)
### 创建流
```sql
create stream stream2 into stream_db.stream2_output_stb as select ts, concat_ws("_", location, tbname) as server_location, round(cpu) as cpu, round(mem) as mem, round(latency) as latency from stream_db.idc partition by tbname order by ts;
create stream power_stream into power_stream_output_stb as select ts, concat_ws(".", location, tbname) as meter_location, current*voltage*cos(phase) as active_power, current*voltage*sin(phase) as reactive_power from meters partition by tbname;
```
### 写入数据
```sql
insert into stream_db.server01 values(now-14h, 50.9, 654.8, 23.11);
insert into stream_db.server01 values(now-13h, 13.5, 221.2, 11.22);

description: "数据订阅与推送服务。写入到 TDengine 中的时序数据能够被自动推送到订阅客户端。"
title: 数据订阅
---
为了帮助应用实时获取写入 TDengine 的数据，或者以事件到达顺序处理数据，TDengine提供了类似消息队列产品的数据订阅、消费接口。这样在很多场景下，采用 TDengine 的时序数据处理系统不再需要集成消息队列产品，比如 kafka, 从而简化系统设计的复杂度，降低运营维护成本。
与 kafka 一样，你需要定义 topic, 但 TDengine 的 topic 是基于一个已经存在的超级表、子表或普通表的查询条件，即一个 SELECT 语句。你可以使用 SQL 对标签、表名、列、表达式等条件进行过滤，以及对数据进行标量函数与 UDF 计算（不包括数据聚合）。与其他消息队列软件相比，这是 TDengine 数据订阅功能的最大的优势，它提供了更大的灵活性，数据的颗粒度可以由应用随时调整，而且数据的过滤与预处理交给 TDengine，而不是应用完成，有效的减少传输的数据量与应用的复杂度。
消费者订阅 topic 后，可以实时获得最新的数据。多个消费者可以组成一个消费者组 (consumer group), 一个消费者组里的多个消费者共享消费进度，便于多线程、分布式地消费数据，提高消费速度。但不同消费者组中的消费者即使消费同一个topic, 并不共享消费进度。一个消费者可以订阅多个 topic。如果订阅的是超级表，数据可能会分布在多个不同的 vnode 上，也就是多个 shard 上，这样一个消费组里有多个消费者可以提高消费效率。TDengine 的消息队列提供了消息的ACK机制，在宕机、重启等复杂环境下确保 at least once 消费。
为了实现上述功能，TDengine 会为 WAL (Write-Ahead-Log) 文件自动创建索引以支持快速随机访问，并提供了灵活可配置的文件切换与保留机制：用户可以按需指定 WAL 文件保留的时间以及大小（详见 create database 语句）。通过以上方式将 WAL 改造成了一个保留事件到达顺序的、可持久化的存储引擎（但由于 TSDB 具有远比 WAL 更高的压缩率，我们不推荐保留太长时间，一般来说，不超过几天）。 对于以 topic 形式创建的查询，TDengine 将对接 WAL 而不是 TSDB 作为其存储引擎。在消费时，TDengine 根据当前消费进度从 WAL 直接读取数据，并使用统一的查询引擎实现过滤、变换等操作，将数据推送给消费者。
本文档不对消息队列本身的基础知识做介绍，如果需要了解，请自行搜索。
## 主要数据结构和API
TMQ 的 API 中，与订阅相关的主要数据结构和API如下：
```c
typedef struct tmq_t tmq_t;
typedef struct tmq_conf_t tmq_conf_t;
typedef struct tmq_list_t tmq_list_t;
typedef void(tmq_commit_cb(tmq_t *, int32_t code, void *param));
DLL_EXPORT tmq_list_t *tmq_list_new();
DLL_EXPORT int32_t tmq_list_append(tmq_list_t *, const char *);
DLL_EXPORT void tmq_list_destroy(tmq_list_t *);
DLL_EXPORT tmq_t *tmq_consumer_new(tmq_conf_t *conf, char *errstr, int32_t errstrLen);
DLL_EXPORT const char *tmq_err2str(int32_t code);
DLL_EXPORT int32_t tmq_subscribe(tmq_t *tmq, const tmq_list_t *topic_list);
DLL_EXPORT int32_t tmq_unsubscribe(tmq_t *tmq);
DLL_EXPORT TAOS_RES *tmq_consumer_poll(tmq_t *tmq, int64_t timeout);
DLL_EXPORT int32_t tmq_consumer_close(tmq_t *tmq);
DLL_EXPORT int32_t tmq_commit_sync(tmq_t *tmq, const TAOS_RES *msg);
DLL_EXPORT void tmq_commit_async(tmq_t *tmq, const TAOS_RES *msg, tmq_commit_cb *cb, void *param);
enum tmq_conf_res_t {
TMQ_CONF_UNKNOWN = -2,
TMQ_CONF_INVALID = -1,
TMQ_CONF_OK = 0,
};
typedef enum tmq_conf_res_t tmq_conf_res_t;
DLL_EXPORT tmq_conf_t *tmq_conf_new();
DLL_EXPORT tmq_conf_res_t tmq_conf_set(tmq_conf_t *conf, const char *key, const char *value);
DLL_EXPORT void tmq_conf_destroy(tmq_conf_t *conf);
DLL_EXPORT void tmq_conf_set_auto_commit_cb(tmq_conf_t *conf, tmq_commit_cb *cb, void *param);
```
这些 API 的文档请见 [C/C++ Connector](/reference/connector/cpp)，下面介绍一下它们的具体用法（超级表和子表结构请参考“数据建模”一节），完整的示例代码可以在 [tmq.c](https://github.com/taosdata/TDengine/blob/3.0/examples/c/tmq.c) 看到。
## 写入数据
首先完成建库、建一张超级表和多张子表操作，然后就可以写入数据了，比如：
```sql
drop database if exists tmqdb;
create database tmqdb;
create table tmqdb.stb (ts timestamp, c1 int, c2 float, c3 varchar(16) tags(t1 int, t3 varchar(16));
create table tmqdb.ctb0 using tmqdb.stb tags(0, "subtable0");
create table tmqdb.ctb1 using tmqdb.stb tags(1, "subtable1");
create table tmqdb.ctb2 using tmqdb.stb tags(2, "subtable2");
create table tmqdb.ctb3 using tmqdb.stb tags(3, "subtable3");
insert into tmqdb.ctb0 values(now, 0, 0, 'a0')(now+1s, 0, 0, 'a00');
insert into tmqdb.ctb1 values(now, 1, 1, 'a1')(now+1s, 11, 11, 'a11');
insert into tmqdb.ctb2 values(now, 2, 2, 'a1')(now+1s, 22, 22, 'a22');
insert into tmqdb.ctb3 values(now, 3, 3, 'a1')(now+1s, 33, 33, 'a33');
```
## 创建topic：
```sql
create topic topicName as select ts, c1, c2, c3 from tmqdb.stb where c1 > 1;
```
TMQ支持多种订阅类型：
### 列订阅
语法：CREATE TOPIC topic_name as subquery
通过select语句订阅（包括select *，或select ts, c1等指定列描述订阅，可以带条件过滤、标量函数计算，但不支持聚合函数、不支持时间窗口聚合）
- TOPIC一旦创建则schema确定
- 被订阅或用于计算的column和tag不可被删除、修改
- 若发生schema变更，新增的column不出现在结果中
### 超级表订阅
语法：CREATE TOPIC topic_name AS STABLE stbName
与select * from stbName订阅的区别是：
- 不会限制用户的schema变更
- 返回的是非结构化的数据：返回数据的schema会随之超级表的schema变化而变化
- 用户对于要处理的每一个数据块都可能有不同的schema，因此，必须重新获取schema
- 返回数据不带有tag
## 创建 consumer 以及consumer group
对于consumer, 目前支持的config包括：
| 参数名称 | 参数值 | 备注 |
| ---------------------------- | ------------------------------ | ------------------------------------------------------ |
| group.id | 最大长度：192 | |
| enable.auto.commit | 合法值：true, false | |
| auto.commit.interval.ms | | |
| auto.offset.reset | 合法值：earliest, latest, none | |
| td.connect.ip | 用于连接，同taos_connect的参数 | |
| td.connect.user | 用于连接，同taos_connect的参数 | |
| td.connect.pass | 用于连接，同taos_connect的参数 | |
| td.connect.port | 用于连接，同taos_connect的参数 | |
| enable.heartbeat.background | 合法值：true, false | 开启后台心跳，即consumer不会因为长时间不poll而认为离线 |
| experimental.snapshot.enable | 合法值：true, false | 从wal开始消费，还是从tsbs开始消费 |
| msg.with.table.name | 合法值：true, false | 从消息中能否解析表名 |
```sql
/* 根据需要，设置消费组(group.id)、自动提交(enable.auto.commit)、自动提交时间间隔(auto.commit.interval.ms)、用户名(td.connect.user)、密码(td.connect.pass)等参数 */
tmq_conf_t* conf = tmq_conf_new();
tmq_conf_set(conf, "enable.auto.commit", "true");
tmq_conf_set(conf, "auto.commit.interval.ms", "1000");
tmq_conf_set(conf, "group.id", "cgrpName");
tmq_conf_set(conf, "td.connect.user", "root");
tmq_conf_set(conf, "td.connect.pass", "taosdata");
tmq_conf_set(conf, "auto.offset.reset", "earliest");
tmq_conf_set(conf, "experimental.snapshot.enable", "true");
tmq_conf_set(conf, "msg.with.table.name", "true");
tmq_conf_set_auto_commit_cb(conf, tmq_commit_cb_print, NULL);
tmq_t* tmq = tmq_consumer_new(conf, NULL, 0);
tmq_conf_destroy(conf);
return tmq;
```
上述配置中包括consumer group ID，如果多个 consumer 指定的 consumer group ID一样，则自动形成一个consumer group，共享消费进度。
## 创建 topic 列表
单个consumer支持同时订阅多个topic。
```sql
tmq_list_t* topicList = tmq_list_new();
tmq_list_append(topicList, "topicName");
return topicList;
```
## 启动订阅并开始消费
```sql
/* 启动订阅 */
tmq_subscribe(tmq, topicList);
tmq_list_destroy(topicList);
/* 循环poll消息 */
int32_t totalRows = 0;
int32_t msgCnt = 0;
int32_t timeOut = 5000;
while (running) {
TAOS_RES* tmqmsg = tmq_consumer_poll(tmq, timeOut);
if (tmqmsg) {
msgCnt++;
totalRows += msg_process(tmqmsg);
taos_free_result(tmqmsg);
} else {
break;
}
}
fprintf(stderr, "%d msg consumed, include %d rows\n", msgCnt, totalRows);
```
这里是一个 **while** 循环，每调用一次tmq_consumer_poll()，获取一个消息，该消息与普通查询返回的结果集完全相同，可以使用相同的解析API完成消息内容的解析：
```sql
static int32_t msg_process(TAOS_RES* msg) {
char buf[1024];
int32_t rows = 0;
const char* topicName = tmq_get_topic_name(msg);
const char* dbName = tmq_get_db_name(msg);
int32_t vgroupId = tmq_get_vgroup_id(msg);
printf("topic: %s\n", topicName);
printf("db: %s\n", dbName);
printf("vgroup id: %d\n", vgroupId);
while (1) {
TAOS_ROW row = taos_fetch_row(msg);
if (row == NULL) break;
TAOS_FIELD* fields = taos_fetch_fields(msg);
int32_t numOfFields = taos_field_count(msg);
int32_t* length = taos_fetch_lengths(msg);
int32_t precision = taos_result_precision(msg);
const char* tbName = tmq_get_table_name(msg);
rows++;
taos_print_row(buf, row, fields, numOfFields);
printf("row content from %s: %s\n", (tbName != NULL ? tbName : "null table"), buf);
}
return rows;
}
```
## 结束消费
```sql
/* 取消订阅 */
tmq_unsubscribe(tmq);
/* 关闭消费 */
tmq_consumer_close(tmq);
```
## 删除topic
如果不再需要，可以删除创建topic，但注意：只有没有被订阅的topic才能别删除。
```sql
/* 删除topic */
drop topic topicName;
```
## 状态查看
1、topics：查询已经创建的topic
```sql
show topics;
```
2、consumers：查询consumer的状态及其订阅的topic
```sql
show consumers;
```
3、subscriptions：查询consumer与vgroup之间的分配关系
```sql
show subscriptions;
```

## 写入数据
首先完成建库、建一张超级表和多张子表操作，然后就可以写入数据了，比如：
```sql
DROP DATABASE IF EXISTS tmqdb;
CREATE DATABASE tmqdb;
CREATE TABLE tmqdb.stb (ts TIMESTAMP, c1 INT, c2 FLOAT, c3 VARCHAR(16) TAGS(t1 INT, t3 VARCHAR(16));
CREATE TABLE tmqdb.ctb0 USING tmqdb.stb TAGS(0, "subtable0");
CREATE TABLE tmqdb.ctb1 USING tmqdb.stb TAGS(1, "subtable1");
INSERT INTO tmqdb.ctb0 VALUES(now, 0, 0, 'a0')(now+1s, 0, 0, 'a00');
INSERT INTO tmqdb.ctb1 VALUES(now, 1, 1, 'a1')(now+1s, 11, 11, 'a11');
```
## 创建 *topic*
TDengine 使用 SQL 创建一个 topic：
```sql
CREATE TOPIC topic_name AS SELECT ts, c1, c2, c3 FROM tmqdb.stb WHERE c1 > 1;
```
TMQ 支持多种订阅类型：
### 列订阅
语法：
```sql
CREATE TOPIC topic_name as subquery
```
通过 `SELECT` 语句订阅（包括 `SELECT *`，或 `SELECT ts, c1` 等指定列订阅，可以带条件过滤、标量函数计算，但不支持聚合函数、不支持时间窗口聚合）。需要注意的是：
- 该类型 TOPIC 一旦创建则订阅数据的结构确定。
- 被订阅或用于计算的列或标签不可被删除（`ALTER table DROP`）、修改（`ALTER table MODIFY`）。
- 若发生表结构变更，新增的列不出现在结果中，若发生列删除则会报错。
### 超级表订阅
语法：
```sql
CREATE TOPIC topic_name AS STABLE stb_name
```
与 `SELECT * from stbName` 订阅的区别是：
- 不会限制用户的表结构变更。
- 返回的是非结构化的数据：返回数据的结构会随之超级表的表结构变化而变化。
- 用户对于要处理的每一个数据块都可能有不同的表结构。
- 返回数据不包含标签。
### 数据库订阅
语法：
```sql
CREATE TOPIC topic_name [WITH META] AS DATABASE db_name;
```
通过该语句可创建一个包含数据库所有表数据的订阅，`WITH META` 可选择将数据库结构变动信息加入到订阅消息流，TMQ 将消费当前数据库下所有表结构的变动，包括超级表的创建与删除，列添加、删除或修改，子表的创建、删除及 TAG 变动信息等等。消费者可通过 API 来判断具体的消息类型。这一点也是与 Kafka 不同的地方。
## 创建消费者 *consumer*
消费者需要通过一系列配置选项创建，基础配置项如下表所示：
| 参数名称 | 类型 | 参数说明 | 备注 |
| :----------------------------: | :-----: | -------------------------------------------------------- | ------------------------------------------- |
| `td.connect.ip` | string | 用于创建连接，同 `taos_connect` | |
| `td.connect.user` | string | 用于创建连接，同 `taos_connect` | |
| `td.connect.pass` | string | 用于创建连接，同 `taos_connect` |
| `td.connect.port` | integer | 用于创建连接，同 `taos_connect` |
| `group.id` | string | 消费组 ID，同一消费组共享消费进度 | **必填项**。最大长度：192。 |
| `client.id` | string | 客户端 ID | 最大长度：192。 |
| `auto.offset.reset` | enum | 消费组订阅的初始位置 | 可选：`earliest`, `latest`, `none`(default) |
| `enable.auto.commit` | boolean | 启用自动提交 | 合法值：`true`, `false`。 |
| `auto.commit.interval.ms` | integer | 以毫秒为单位的自动提交时间间隔 |
| `enable.heartbeat.background` | boolean | 启用后台心跳，启用后即使长时间不 poll 消息也不会造成离线 | |
| `experimental.snapshot.enable` | boolean | 从 WAL 开始消费，还是从 TSBS 开始消费 | |
| `msg.with.table.name` | boolean | 是否允许从消息中解析表名 |
对于不同编程语言，其设置方式如下：
<Tabs defaultValue="java" groupId="lang">
<TabItem value="c" label="C">
```c
/* 根据需要，设置消费组 (group.id)、自动提交 (enable.auto.commit)、
自动提交时间间隔 (auto.commit.interval.ms)、用户名 (td.connect.user)、密码 (td.connect.pass) 等参数 */
tmq_conf_t* conf = tmq_conf_new();
tmq_conf_set(conf, "enable.auto.commit", "true");
tmq_conf_set(conf, "auto.commit.interval.ms", "1000");
tmq_conf_set(conf, "group.id", "cgrpName");
tmq_conf_set(conf, "td.connect.user", "root");
tmq_conf_set(conf, "td.connect.pass", "taosdata");
tmq_conf_set(conf, "auto.offset.reset", "earliest");
tmq_conf_set(conf, "experimental.snapshot.enable", "true");
tmq_conf_set(conf, "msg.with.table.name", "true");
tmq_conf_set_auto_commit_cb(conf, tmq_commit_cb_print, NULL);
tmq_t* tmq = tmq_consumer_new(conf, NULL, 0);
tmq_conf_destroy(conf);
```
</TabItem>
<TabItem value="java" label="Java">
对于 Java 程序，使用如下配置项：
| 参数名称 | 类型 | 参数说明 |
| ----------------------------- | ------ | ----------------------------------------------------------------------------------------------------------------------------- |
| `bootstrap.servers` | string | 连接地址，如 `localhost:6030` |
| `value.deserializer` | string | 值解析方法，使用此方法应实现 `com.taosdata.jdbc.tmq.Deserializer` 接口或继承 `com.taosdata.jdbc.tmq.ReferenceDeserializer` 类 |
| `value.deserializer.encoding` | string | 指定字符串解析的字符集 | |
需要注意：此处使用 `bootstrap.servers` 替代 `td.connect.ip` 和 `td.connect.port`，以提供与 Kafka 一致的接口。
```java
Properties properties = new Properties();
properties.setProperty("enable.auto.commit", "true");
properties.setProperty("auto.commit.interval.ms", "1000");
properties.setProperty("group.id", "cgrpName");
properties.setProperty("bootstrap.servers", "127.0.0.1:6030");
properties.setProperty("td.connect.user", "root");
properties.setProperty("td.connect.pass", "taosdata");
properties.setProperty("auto.offset.reset", "earliest");
properties.setProperty("msg.with.table.name", "true");
properties.setProperty("value.deserializer", "com.taos.example.MetersDeserializer");
TaosConsumer<Meters> consumer = new TaosConsumer<>(properties);
/* value deserializer definition. */
import com.taosdata.jdbc.tmq.ReferenceDeserializer;
public class MetersDeserializer extends ReferenceDeserializer<Meters> {
}
```
</TabItem>
<TabItem label="Go" value="Go">

}
```
</TabItem>
</Tabs>
上述配置中包括 consumer group ID，如果多个 consumer 指定的 consumer group ID 一样，则自动形成一个 consumer group，共享消费进度。
## 订阅 *topics*
一个 consumer 支持同时订阅多个 topic。
<Tabs defaultValue="java" groupId="lang">
<TabItem value="c" label="C">
```c
// 创建订阅 topics 列表
tmq_list_t* topicList = tmq_list_new();
tmq_list_append(topicList, "topicName");
// 启动订阅
tmq_subscribe(tmq, topicList);
tmq_list_destroy(topicList);
```
</TabItem>
<TabItem value="java" label="Java">
```java
List<String> topics = new ArrayList<>();
topics.add("tmq_topic");
consumer.subscribe(topics);
```
</TabItem>
<TabItem value="Go" label="Go">
```go
consumer, err := tmq.NewConsumer(config)
if err != nil {
panic(err)
}
err = consumer.Subscribe([]string{"example_tmq_topic"})
if err != nil {
panic(err)
}
```
</TabItem>
</Tabs>
## 消费
以下代码展示了不同语言下如何对 TMQ 消息进行消费。
<Tabs defaultValue="java" groupId="lang">
<TabItem value="c" label="C">
```c
// 消费数据
while (running) {
TAOS_RES* msg = tmq_consumer_poll(tmq, timeOut);
msg_process(msg);
}
```
这里是一个 **while** 循环，每调用一次 tmq_consumer_poll()，获取一个消息，该消息与普通查询返回的结果集完全相同，可以使用相同的解析 API 完成消息内容的解析。
</TabItem>
<TabItem value="java" label="Java">
```java
while(running){
ConsumerRecords<Meters> meters = consumer.poll(Duration.ofMillis(100));
for (Meters meter : meters) {
processMsg(meter);
}
}
```
</TabItem>
<TabItem value="Go" label="Go">
```go
for {
result, err := consumer.Poll(time.Second)
if err != nil {
panic(err)
}
fmt.Println(result)
consumer.Commit(context.Background(), result.Message)
consumer.FreeMessage(result.Message)
}
```
</TabItem>
</Tabs>
## 结束消费
消费结束后，应当取消订阅。
<Tabs defaultValue="java" groupId="lang">
<TabItem value="c" label="C">
```c
/* 取消订阅 */
tmq_unsubscribe(tmq);
/* 关闭消费者对象 */
tmq_consumer_close(tmq);
```
</TabItem>
<TabItem value="java" label="Java">
```java
/* 取消订阅 */
consumer.unsubscribe();
/* 关闭消费 */
consumer.close();
```
</TabItem>
<TabItem value="Go" label="Go">
```go
consumer.Close()
```
</TabItem>
</Tabs>
## 删除 *topic*
如果不再需要订阅数据，可以删除 topic，需要注意：只有当前未在订阅中的 TOPIC 才能被删除。
```sql
/* 删除 topic */
DROP TOPIC topic_name;
```
## 状态查看
1、*topics*：查询已经创建的 topic
```sql
SHOW TOPICS;
```
2、consumers：查询 consumer 的状态及其订阅的 topic
```sql
SHOW CONSUMERS;
```
3、subscriptions：查询 consumer 与 vgroup 之间的分配关系
```sql
SHOW SUBSCRIPTIONS;
```
## 示例代码
以下是各语言的完整示例代码。

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。
5. 如果你要基于时序数据做实时的统计分析，包括各种监测看板，那么建议你采用TDengine的连续查询功能，而不用上线Spark, Flink等复杂的流式计算系统。
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。

## 创建订阅主题
```sql
CREATE TOPIC [IF NOT EXISTS] topic_name AS {subquery | DATABASE db_name | STABLE stb_name };
CREATE TOPIC [IF NOT EXISTS] topic_name AS subquery;
```
订阅主题包括三种：列订阅、超级表订阅和数据库订阅。
**列订阅是**用 subquery 描述，支持过滤和标量函数和 UDF 标量函数，不支持 JOIN、GROUP BY、窗口切分子句、聚合函数和 UDF 聚合函数。列订阅规则如下：
TOPIC 支持过滤和标量函数和 UDF 标量函数，不支持 JOIN、GROUP BY、窗口切分子句、聚合函数和 UDF 聚合函数。列订阅规则如下：
1. TOPIC 一旦创建则返回结果的字段确定
2. 被订阅或用于计算的列不可被删除、修改
3. 列可以新增，但新增的列不出现在订阅结果字段中
4. 对于 select \*，则订阅展开为创建时所有的列（子表、普通表为数据列，超级表为数据列加标签列）
**超级表订阅和数据库订阅**规则如下：
1. 被订阅主体的 schema 变更不受限
2. 返回消息中 schema 是块级别的，每块的 schema 可能不一样
3. 列变更后写入的数据若未落盘，将以写入时的 schema 返回
4. 列变更后写入的数据若未已落盘，将以落盘时的 schema 返回

**支持版本**
该功能接口从 2.3.0.0 版本开始支持。
### 订阅和消费 API
订阅 API 目前支持订阅一张或多张表，并通过定期轮询的方式不断获取写入表中的最新数据。
- `TAOS_SUB *taos_subscribe(TAOS* taos, int restart, const char* topic, const char *sql, TAOS_SUBSCRIBE_CALLBACK fp, void *param, int interval)`
该函数负责启动订阅服务，成功时返回订阅对象，失败时返回 `NULL`，其参数为：
- taos：已经建立好的数据库连接
- restart：如果订阅已经存在，是重新开始，还是继续之前的订阅
- topic：订阅的主题（即名称），此参数是订阅的唯一标识
- sql：订阅的查询语句，此语句只能是 `select` 语句，只应查询原始数据，只能按时间正序查询数据
- fp：收到查询结果时的回调函数（稍后介绍函数原型），只在异步调用时使用，同步调用时此参数应该传 `NULL`
- param：调用回调函数时的附加参数，系统 API 将其原样传递到回调函数，不进行任何处理
- interval：轮询周期，单位为毫秒。异步调用时，将根据此参数周期性的调用回调函数，为避免对系统性能造成影响，不建议将此参数设置的过小；同步调用时，如两次调用 `taos_consume()` 的间隔小于此周期，API 将会阻塞，直到时间间隔超过此周期。
- `typedef void (*TAOS_SUBSCRIBE_CALLBACK)(TAOS_SUB* tsub, TAOS_RES *res, void* param, int code)`
异步模式下，回调函数的原型，其参数为：
- tsub：订阅对象
- res：查询结果集，注意结果集中可能没有记录
- param：调用 `taos_subscribe()` 时客户程序提供的附加参数
- code：错误码
:::note
在这个回调函数里不可以做耗时过长的处理，尤其是对于返回的结果集中数据较多的情况，否则有可能导致客户端阻塞等异常状态。如果必须进行复杂计算，则建议在另外的线程中进行处理。
:::
- `TAOS_RES *taos_consume(TAOS_SUB *tsub)`
同步模式下，该函数用来获取订阅的结果。 用户应用程序将其置于一个循环之中。 如两次调用 `taos_consume()` 的间隔小于订阅的轮询周期，API 将会阻塞，直到时间间隔超过此周期。如果数据库有新记录到达，该 API 将返回该最新的记录，否则返回一个没有记录的空结果集。 如果返回值为 `NULL`，说明系统出错。 异步模式下，用户程序不应调用此 API。
:::note
在调用 `taos_consume()` 之后，用户应用应确保尽快调用 `taos_fetch_row()` 或 `taos_fetch_block()` 来处理订阅结果，否则服务端会持续缓存查询结果数据等待客户端读取，极端情况下会导致服务端内存消耗殆尽，影响服务稳定性。
:::
- `void taos_unsubscribe(TAOS_SUB *tsub, int keepProgress)`
取消订阅。 如参数 `keepProgress` 不为 0，API 会保留订阅的进度信息，后续调用 `taos_subscribe()` 时可以基于此进度继续；否则将删除进度信息，后续只能重新开始读取数据。

一个 vnode 启动时，角色（leader、follower）是不定的，数据是处于未同步状态，它需要与虚拟节点组内其他节点建立 TCP 连接，并互相交换 status，按照标准的 raft 一致性算法完成选主。
更多的关于数据复制的流程，请见[《TDengine 3.0 数据复制模块设计》](/tdinternal/replica/)。
### 同步复制
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。

## 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。
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、qnode、mnode 节点协同完成，一个复杂的超级表聚合查询可能需要多个 vnode 和 qnode 节点公共分担查询和计算任务。
### 单表查询
### 查询基本流程
SQL 语句的解析和校验工作在客户端完成。解析 SQL 语句并生成抽象语法树（Abstract Syntax Tree，AST），然后对其进行校验和检查。以及向管理节点（mnode）请求查询中指定表的元数据信息（table metadata）。
根据元数据信息中的 End Point 信息，将查询请求序列化后发送到该表所在的数据节点（dnode）。dnode 接收到查询请求后，识别出该查询请求指向的虚拟节点（vnode），将消息转发到 vnode 的查询执行队列。vnode 的查询执行线程建立基础的查询执行环境，并立即返回该查询请求，同时开始执行该查询。
客户端在获取查询结果的时候，dnode 的查询执行队列中的工作线程会等待 vnode 执行线程执行完成，才能将查询结果返回到请求的客户端。
1. 客户端解析输入 SQL 语句并生成抽象语法树（Abstract Syntax Tree，AST），然后根据元数据信息对其进行校验和检查。在此期间，元数据管理模块（Catalog）会向管理节点（mnode）或 vnode 请求查询中指定库和表的元数据信息（table metadata）。
2. 在通过校验检查后，客户端将生成分布式的查询计划并对查询计划进行优化处理。
3. 客户端根据配置的查询策略进行任务调度处理，一个查询子任务会根据其数据亲缘关系或负载信息调度到某个 vnode 或 qnode 所属的数据节点（dnode）进行处理。
4. dnode 接收到查询请求后，识别出该查询请求指向的虚拟节点（vnode）或查询节点（qnode），将消息转发到 vnode 或 qnode 的查询执行队列。
5. vnode 或 qnode 的查询执行线程建立基础的查询执行环境，并立即执行该查询，在得到部分可获取查询结果后通知客户端。
6. 客户端将启动下级查询任务或直接获取查询结果。

<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。
1. 客户端从 mnode 获取库和表的元数据信息；
2. mnode 返回请求的元数据信息；
3. 客户端向超级表所属的每个 vnode 发送查询请求；
4. vnode 启动本地查询，在获得查询结果后返回查询响应；
5. 客户端向聚合节点 （在本例中为 qnode）发送查询请求；
6. qnode 向每个 vnode 节点发送数据请求消息来拉取数据；
7. vnode 返回本节点的查询计算结果；
8. qnode 完成多节点数据聚合后将最终查询结果返回给客户端；
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。
