Specifies the Kafka bootstrap servers that the provider uses to establish the initial connection to the Kafka cluster.

Data Type

string

Default Value

""

Remarks

Specify each server using a hostname or IP address followed by a port number. For example: 10.1.2.3:9092. You may provide multiple comma-separated addresses. The connection succeeds as long as the driver can reach at least one of the listed servers.

Kafka bootstrap servers are not responsible for all messaging traffic. They are used only to retrieve metadata, after which the driver connects to the appropriate brokers in the cluster.

If you are connecting to Confluent Cloud, the bootstrap server address is available in the Cluster settings.
