We are using Apache kafka_2.11-1.1.0. Whenever we want to add a new Kafka producer or consumer, we update the new certificate in truststore. Once the cert is added, we have to restart the kafka cluster. Is there a way to add cert without Rolling restart of Kafka ? Technically the truststore update shouldn't require Kafka to restart.

I too had same question, the official documentation tells about rolling updates...one broker at a time, but that leads to too much of rebalancing on a heavily loaded cluster. Any alternatives? – Atul Kumar Feb 12 '21 at 09:53
