-##### Create Consumer
-
-The syntax for creating a consumer is `consumer = Consumer(configs)`. For more subscription api parameters, please refer to [Data Subscription](../../../develop/tmq/).
-
-```python
-from taos.tmq import Consumer
-
-consumer = Consumer({"group.id": "local", "td.connect.ip": "127.0.0.1"})

-##### Subscribe topics
-
-The `subscribe` function is used to subscribe to a list of topics.
-
-```python
-consumer.subscribe(['topic1', 'topic2'])
-```
-
-##### Consume
-
-The `poll` function is used to consume data in tmq. The parameter of the `poll` function is a value of type float representing the timeout in seconds. It returns a `Message` before timing out, or `None` on timing out. You have to handle error messages in response data.
-
-```python
-while True:
-    res = consumer.poll(1)
-    if not res:
-        continue
-    err = res.error()
-    if err is not None:

-    val = res.value()
-
-    for block in val:
-        print(block.fetchall())

-
-##### assignment
-
-The `assignment` function is used to get the assignment of the topic. 
-
-```python
-assignments = consumer.assignment()

-
-##### Seek
-
-The `seek` function is used to reset the assignment of the topic.
-
-```python
-tp = TopicPartition(topic='topic1', partition=0, offset=0)
-consumer.seek(tp)
-```
-
-##### After consuming data
-
-You should unsubscribe to the topics and close the consumer after consuming.

-
-consumer = Consumer({"group.id": "local", "td.connect.ip": "127.0.0.1"})

-
-##### 订阅 topics
-
-Consumer API 的 `subscribe` 方法用于订阅 topics，consumer 支持同时订阅多个 topic。
-
-```python
-consumer.subscribe(['topic1', 'topic2'])
-```
-
-##### 消费数据
-
-Consumer API 的 `poll` 方法用于消费数据，`poll` 方法接收一个 float 类型的超时时间，超时时间单位为秒（s），`poll` 方法在超时之前返回一条 Message 类型的数据或超时返回 `None`。消费者必须通过 Message 的 `error()` 方法校验返回数据的 error 信息。
-
-```python
-while True:
-    res = consumer.poll(1)
-    if not res:
-        continue
-    err = res.error()
-    if err is not None:

-    val = res.value()
-
-    for block in val:
-        print(block.fetchall())
-```
-
-##### 获取消费进度
-
-Consumer API 的 `assignment` 方法用于获取 Consumer 订阅的所有 topic 的消费进度，返回结果类型为 TopicPartition 列表。
-
-```python
-assignments = consumer.assignment()
-```
-
-##### 指定订阅 Offset
-
-Consumer API 的 `seek` 方法用于重置 Consumer 的消费进度到指定位置，方法参数类型为 TopicPartition。
-
-```python
-tp = TopicPartition(topic='topic1', partition=0, offset=0)
-consumer.seek(tp)
-```
-
-##### 关闭订阅
-
-消费结束后，应当取消订阅，并关闭 Consumer。
