To implement these features, TDengine indexes its write-ahead log (WAL) file for fast random access and provides configurable methods for replacing and retaining this file. You can define a retention period and size for this file. For information, see the CREATE DATABASE statement. In this way, the WAL file is transformed into a persistent storage engine that remembers the order in which events occur. However, note that configuring an overly long retention period for your WAL files makes database compression inefficient. TDengine then uses the WAL file instead of the time-series database as its storage engine for queries in the form of topics. TDengine reads the data from the WAL file; uses a unified query engine instance to perform filtering, transformations, and other operations; and finally pushes the data to consumers.
Tips: Data subscription is to consume data from the wal. If some wal files are deleted according to WAL retention policy, the deleted data can't be consumed any more. So you need to set a reasonable value for parameter `WAL_RETENTION_PERIOD` or `WAL_RETENTION_SIZE` when creating the database and make sure your application consume the data in a timely way to make sure there is no data loss. This behavior is similar to Kafka and other widely used message queue products.
Tips:(c interface for example)
- A consumption group consumes all data under the same topic, and different consumption groups are independent of each other;
- A consumption group consumes all vgroups of the same topic, which can be composed of multiple consumers, but a vgroup is only consumed by one consumer. If the number of consumers exceeds the number of vgroups, the excess consumers do not consume data;
- On the server side, only one offset is saved for each vgroup, and the offsets for each vgroup are monotonically increasing, but not necessarily continuous. There is no correlation between the offsets of various vgroups;
- Each poll server will return a result block, which belongs to a vgroup and may contain data from multiple versions of wal. This block can be accessed through tmq_get_vgroup_offset. The offset interface obtains the offset of the first record in the block;
- If a consumer group has never committed an offset, when its member consumers restart and pull data again, they start consuming from the set value of the parameter auto.offset.reset; In a consumer lifecycle, the client locally records the offset of the most recent pull data and will not pull duplicate data;
- If a consumer terminates abnormally (without calling tmq_close), they need to wait for about 12 seconds to trigger their consumer group rebalance. The consumer's status on the server will change to LOST, and after about 1 day, the consumer will be automatically deleted; Exit normally, and after exiting, the consumer will be deleted; Add a new consumer, wait for about 2 seconds to trigger Rebalance, and the consumer's status on the server will change to ready;
- The consumer group Rebalance will reassign Vgroups to all consumer members in the ready state of the group, and consumers can only assign/see/commit/poll operations to the Vgroups they are responsible for;
- Consumers can tmq_position to obtain the offset of the current consumption, seek to the specified offset, and consume again;
- Seek points the position to the specified offset without executing the commit operation. Once the seek is successful, it can poll the specified offset and subsequent data;
- Position is to obtain the current consumption position, which is the position to be taken next time, not the current consumption position
- Commit is the submission of the consumption location. Without parameters, it is the submission of the current consumption location (the location to be taken next time, not the current consumption location). With parameters, it is the location in the submission parameters (i.e. the location to be taken after the next exit and restart)
- Seek is to set the consumer's consumption position. Wherever the seek goes, the position will be returned, all of which are the positions to be taken next time
- Seek does not affect commit, commit does not affect seek, independent of each other, the two are different concepts
- The begin interface is the offset of the first data in wal, and the end interface is the offset+1 of the last data in wal10.
- Before the seek operation, tmq must be call tmq_get_topic_assignment, The assignment interface obtains the vgroup ID and offset range of the consumer. The seek operation will detect whether the vgroup ID and offset are legal, and if they are illegal, an error will be reported;
- Due to the existence of a WAL expiration deletion mechanism, even if the seek operation is successful, it is possible that the offset has expired when polling data. If the offset of poll is less than the WAL minimum version number, it will be consumed from the WAL minimum version number;
- The tmq_get_vgroup_offset interface obtains the offset of the first data in the result block where the record is located. When seeking to this offset, it will consume all the data in this block. Refer to point four;
- Data subscription is to consume data from the wal. If some wal files are deleted according to WAL retention policy, the deleted data can't be consumed any more. So you need to set a reasonable value for parameter `WAL_RETENTION_PERIOD` or `WAL_RETENTION_SIZE` when creating the database and make sure your application consume the data in a timely way to make sure there is no data loss. This behavior is similar to Kafka and other widely used message queue products.

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。
注意：数据订阅是从 WAL 消费数据，如果一些 WAL 文件被基于 WAL 保留策略删除，则已经删除的 WAL 文件中的数据就无法再消费到。需要根据业务需要在创建数据库时合理设置 `WAL_RETENTION_PERIOD` 或 `WAL_RETENTION_SIZE` ，并确保应用及时消费数据，这样才不会产生数据丢失的现象。数据订阅的行为与 Kafka 等广泛使用的消息队列类产品的行为相似。
说明（以c接口为例）：
- 一个消费组消费同一个topic下的所有数据，不同消费组之间相互独立；
- 一个消费组消费同一个topic所有的vgroup，消费组可由多个消费者组成，但一个vgroup仅被一个消费者消费，如果消费者数量超过了vgroup数量，多余的消费者不消费数据；
- 在服务端每个vgroup仅保存一个offset，每个vgroup的offset是单调递增的，但不一定连续。各个vgroup的offset之间没有关联；
- 每次poll服务端会返回一个结果block，该block属于一个vgroup，可能包含多个wal版本的数据，可以通过 tmq_get_vgroup_offset 接口获得是该block第一条记录的offset；
- 一个消费组如果从未commit过offset，当其成员消费者重启重新拉取数据时，均从参数auto.offset.reset设定值开始消费；在一个消费者生命周期中，客户端本地记录了最近一次拉取数据的offset，不会拉取重复数据；
- 消费者如果异常终止（没有调用tmq_close），需等约12秒后触发其所属消费组rebalance，该消费者在服务端状态变为LOST，约1天后该消费者自动被删除；正常退出，退出后就会删除消费者；新增消费者，需等约2秒触发rebalance，该消费者在服务端状态变为ready；
- 消费组rebalance会对该组所有ready状态的消费者成员重新进行vgroup分配，消费者仅能对自己负责的vgroup进行assignment/seek/commit/poll操作；
- 消费者可利用 tmq_position 获得当前消费的offset，并seek到指定offset，重新消费；
- seek将position指向指定offset，不执行commit操作，一旦seek成功，可poll拉取指定offset及以后的数据；
- seek 操作之前须调用 tmq_get_topic_assignment 接口获取该consumer的vgroup ID和offset范围。seek 操作会检测vgroup ID 和 offset是否合法，如非法将报错；
- position是获取当前的消费位置，是下次要取的位置，不是当前消费到的位置
- commit是提交消费位置，不带参数的话，是提交当前消费位置（下次要取的位置，不是当前消费到的位置），带参数的话，是提交参数里的位置（也即下次退出重启后要取的位置）
- seek是设置consumer消费位置，seek到哪，position就返回哪，都是下次要取的位置
- seek不会影响commit，commit不影响seek，相互独立，两个是不同的概念
- begin接口为wal 第一条数据的offset，end 接口为wal 最后一条数据的offset + 1
- tmq_get_vgroup_offset接口获取的是记录所在结果block块里的第一条数据的offset，当seek至该offset时，将消费到这个block里的全部数据。参见第四点；
- 由于存在 WAL 过期删除机制，即使seek 操作成功，poll数据时有可能offset已失效。如果poll 的offset 小于 WAL 最小版本号，将会从WAL最小版本号消费；
- 数据订阅是从 WAL 消费数据，如果一些 WAL 文件被基于 WAL 保留策略删除，则已经删除的 WAL 文件中的数据就无法再消费到。需要根据业务需要在创建数据库时合理设置 `WAL_RETENTION_PERIOD` 或 `WAL_RETENTION_SIZE` ，并确保应用及时消费数据，这样才不会产生数据丢失的现象。数据订阅的行为与 Kafka 等广泛使用的消息队列类产品的行为相似；

tmq_topic_assignment结构体定义如下：
```c
typedef struct tmq_topic_assignment {
int32_t vgId;
int64_t currentOffset;
int64_t begin;
int64_t end;
} tmq_topic_assignment;
```
**功能说明**
- tmq_get_topic_assignment 接口返回当前consumer分配的vgroup的信息，每个vgroup的信息包括vgId，wal的最大最小offset，以及当前消费到的offset。
**参数说明**
- numOfAssignment ：分配给该consumer有效的vgroup个数。
- assignment ：分配的信息，数据大小为numOfAssignment，需要通过 tmq_free_assignment 接口释放。
**返回值**
- 错误码，0成功，非0失败，可通过 `char *tmq_err2str(int32_t code)` 函数获取错误信息。

- 第一种类型：根据消息提交，提交消息里的进度，如果消息传NULL，提交当前consumer所有消费的vgroup的当前进度 : tmq_commit_sync/tmq_commit_async
- 第二种类型：根据某个topic的某个vgroup的offset提交 : tmq_commit_offset_sync/tmq_commit_offset_async
**参数说明**
- msg：消费到的消息结构，如果msg传NULL，提交当前consumer所有消费的vgroup的当前进度
**返回值**
- 错误码，0成功，非0失败，可通过 `char *tmq_err2str(int32_t code)` 函数获取错误信息

- 执行 `RESET QUERY CACHE` 可清除本地表 Schema 的缓存
- 批量执行 SQL 语句。可以将一系列的 TDengine CLI 命令（以英文 ; 结尾，每个 SQL 语句为一行）按行存放在文件里，在 TDengine CLI 里执行命令 `source <file-name>` 自动执行该文件里所有的 SQL 语句
- 输入 `q` 或 `quit` 或 `exit` 回车，可以退出 TDengine CLI
## TDengine CLI 导出查询结果到文件中
- 可以使用符号 “>>” 导出查询结果到某个文件中，语法为： sql 查询语句 >> ‘输出文件名’; 输出文件如果不写路径的话，将输出至当前目录下。如 select * from d0 >> ‘/root/d0.csv’; 将把查询结果输出到 /root/d0.csv 中。
## TDengine CLI 导入文件中的数据到表中
- 可以使用 insert into table_name file '输入文件名'，把上一步中导出的数据文件再导入到指定表中。如 insert into d0 file '/root/d0.csv'; 表示把上面导出的数据全部再导致至 d0 表中。
