-基于数据天然的时间序列特性，TDengine 的数据写入（insert）与消息系统的数据发布（pub）逻辑上一致，均可视为系统中插入一条带时间戳的新记录。同时，TDengine 在内部严格按照数据时间序列单调递增的方式保存数据。本质上来说，TDengine 中每一张表均可视为一个标准的消息队列。
+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。
 
-TDengine 内嵌支持消息订阅与推送服务（下文都简称TMQ）。使用系统提供的 API，用户可使用普通查询语句订阅数据库中的一张或多张表，或整个库。客户端启动订阅后，定时或按需轮询服务器是否有新的记录到达，有新的记录到达就会将结果反馈到客户。
+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。
 
-TMQ提供了提交机制来保证消息队列的可靠性和正确性。在调用方法上，支持自动提交和手动提交。
+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。
+

 在有些应用场景中，应用逻辑需要的查询无法直接使用系统内置的函数来表示。利用 UDF 功能，TDengine 可以插入用户编写的处理代码并在查询中使用它们，就能够很方便地解决特殊应用场景中的使用需求。 UDF 通常以数据表中的一列数据做为输入，同时支持以嵌套子查询的结果作为输入。

-
-在创建 UDF 时，需要区分标量函数和聚合函数。如果创建时声明了错误的函数类别，则可能导致通过 SQL 指令调用函数时出错。此外，用户需要保证输入数据类型与 UDF 程序匹配，UDF 输出数据类型与 OUTPUTTYPE 匹配。
-
-- 创建标量函数
-```sql
-CREATE FUNCTION function_name AS library_path OUTPUTTYPE output_type;
-```
-
-  - function_name：标量函数未来在 SQL 中被调用时的函数名，必须与函数实现中 udf 的实际名称一致；
-  - library_path：包含 UDF 函数实现的动态链接库的库文件绝对路径（指的是库文件在当前客户端所在主机上的保存路径，通常是指向一个 .so 文件），这个路径需要用英文单引号或英文双引号括起来；
-  - output_type：此函数计算结果的数据类型名称；
-
-  例如，如下语句可以把 libbitand.so 创建为系统中可用的 UDF：
-
-  ```sql
-  CREATE FUNCTION bit_and AS "/home/taos/udf_example/libbitand.so" OUTPUTTYPE INT;
-  ```
-
-- 创建聚合函数：
-```sql

-  - library_path：包含 UDF 函数实现的动态链接库的库文件绝对路径（指的是库文件在当前客户端所在主机上的保存路径，通常是指向一个 .so 文件），这个路径需要用英文单引号或英文双引号括起来；
-  - output_type：此函数计算结果的数据类型，与上文中 udfNormalFunc 的 itype 参数不同，这里不是使用数字表示法，而是直接写类型名称即可；
-  - buffer_size：中间计算结果的缓冲区大小，单位是字节。如果不使用可以不设置。
-
-  例如，如下语句可以把 libsqrsum.so 创建为系统中可用的 UDF：
-
-  ```sql
-  CREATE AGGREGATE FUNCTION sqr_sum AS "/home/taos/udf_example/libsqrsum.so" OUTPUTTYPE DOUBLE bufsize 8;

-- 显示系统中当前可用的所有 UDF：

+TDengine is a high-efficient, scalable, high-available distributed time-series database, which makes a lot of optimizations on inserting and querying data, which is far more efficient than normal regular databases. So TDengine can meet the high requirements of IOT and other areas on storing and querying a large amount of data. 
+
+TDengine will be installed under C:\TDengine, users can modify configuration file C:\TDengine\cfg\taos.cfg, set the log file path or other parameters.
