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。

**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。
