Question about commit and disconnect after connection is lost

I noticed that when commit is called while connection to kafka is lost, the function never returns or throws any error.

How should I recover from this state?

I could set a timeout and assume the connection is lost if the function does not return within that period and try to establish connection with a different kafka server. However, the disconnect function does not return either when connection is lost. How do I perform the necessary clean up without the disconnect function?

Thanks in advance
