What is the best way to ensure connectivity to Kafka without polling any messages

[Anas Mosaad <an...@incorta.com>]

Hi All,

I am new to Kafka, I want to make sure Kafka server is available before I
can do any polling to the messages. What I did is creating a consumer
without subscription and try to access the partitions metadata for a
specific topic. This trick works for the first time. If I take the brokers
down and get one up and test the connectivity, it fails.

My problem is, I am not sure if this is the right way to ensure
connectivity. I appreciate any feedback about the best way to do this on
Kafka 0.9.0.1.

Thanks!

What we normally do is consumer.poll(0). This connects to the broker,
finds the consumer group, handles partition assignment, gets the
metadata - and then doesn't stick around to actually give you any
data.

Pretty hacky, but we use this all over the place.
