Unable to create multiple consumers for different topics in the same process?

[mango009]

I create multiple consumers running in different Go routines. These consumers consume messages on different topics.

But I notice that when one consumer is blocked processing messages, the other consumer would get timeout error on the ReadMessage function.

Is it not a practice to create multiple consumers in the same process?

Does each routine run one consumer group?

One consumer can already subscribe to a regex pattern of topic names.

Sub-processing is an alternative solution than coroutines

[mango009]

Yes. Each consumer group run in it's own go routine. I know alternative is to subscribe multiple topic in one go routine. But the API doesn't preclude subscribing one topic in separate go routine. And if this is a bad practice it would helpful to state this in the document (and maybe give a reason).

Can you please share an example? Also, do they all share a config? Specifically all a single group.id
