描述

Description

Feature request. When pausing a consumer, it would be nice if there was a way to check if the consumer is paused. For example a consumer could be paused / resumed based on various conditions and the user may want to know the current state of the consumer. Currently the only way to do this would be to store the state externally in another variable.

How to reproduce

from confluent_kafka import Consumer

c = Consumer({...})
c.subscribe(topics)
c.pause(topic_partitions)
# how to check if the consumer is paused?

Ideally the consumer would have a method like .is_consumer_paused() or a property .paused

研究方向
The feature request is to add a method or property to check if a consumer is paused. Look at the existing `pause()` and `resume()` methods in the `Consumer` class to understand how the paused state is managed. Likely, the state is stored in the underlying C `librdkafka` handle. You may need to expose a new method that calls the C function to retrieve the paused partitions. Consider adding a `paused()` method that returns a boolean or list of paused topic partitions. Refer to the `confluent kafka/src/Consumer.c` or similar files for the C extension implementation.
