How to find group.id property of a kafka topic in Amazon MSK?

I am trying to consume messages from a Kafka topic in Amazon MSK using Apache NiFi. NiFi ConsumeKafka processor requires group.id property of Kafka.Where or How can I find the group.id property for the MSK cluster?

Solution

You can set the group.id property to whatever you want - this simply allows you to group multiple consumers (i.e. multiple NiFi nodes) together to consume from a single topic concurrently.
