Confluent Kafka Header Ports

The Confluent Kafka data object contains default header ports that represent metadata associated with events.

The following table describes the header ports of the Confluent Kafka data object:

Header ports	Data type	Description
partitionId	integer	Partition ID of the data. When the Confluent Kafka topic is divided into partitions, a sequential ID is assigned to each event and is unique to each event within the partition. Use the partition ID to identify the event that you want to consume from a particular partition.
key	binary	Key value associated with an event. You can group events based on the key value and then process the data.
TopicName	string	Name of the Confluent Kafka topic from where you receive events.
