Yes, there is no such "synchronous subscribe" method in Kafka.
Consumer group will start to work after `poll` is called.
Inside Kafka, there are util methods like `awaitAssignment` or
`awaitRebalance` to wait for the initialization completed for tests, which
is checking with `poll`

It will not interfere. And this is independent of manual partition
assignment or topic subscription. If you have different consumer
group-ids it's independent of each other.

It depends. If auto.topic.create.enable is true, a topic will be created.
If its false, you will get some kind of topic doesn't exist exception.

Hi Mansi,
1) subscribe is a lazy call: only the subsequent poll() will do the leg
work of talking to broker, registering the subscription, getting assigned
partitions and issuing fetch requests to the partition leaders.
2) currently the timeout value for poll() does not count for the time
Hi,
I had a question around expected behavior / API expectations.
Is subscribe a lazy call? What I mean by that is if I subscribe to a topic and
then call poll(0), then is this first poll guaranteed to never return data?
Will the data pre-fetch not start as soon as subscribe is called? Is
Oops! So sorry about that...

I suppose I should have added one qualification to that. The commit API
will not work for a consumer using manual assignment if its groupId is
shared with another consumer using automatic assignment (with subscribe()).
When a consumer group is active, Kafka only allows commits from members of

The commit API should work the same regardless whether subscribe() or
