KafkaListTopics

Gets the list of topics available from a Kafka broker.

Syntax

KafkaListTopics(USING PARAMETERS brokers='hostname:port[,hostname2:port2...]'
                                 [, kafka_conf='kafka_configuration_setting']
                                 [, timeout=timeout_sec])

brokers

The host name and port number of the broker to query for a topic list. You can supply more than one broker as a comma-separated list. However, the returned list will only contains the topics served by the last broker in the list.

kafka_conf

A JSON-formatted object of option/value pairs to pass directly to the rdkafka library. This is the library Vertica uses to communicate with Kafka. You can use this parameter to directly set configuration options that are not available through the Vertica integration with Kafka. See Directly setting Kafka library options for details.

kafka_conf_secret

Conceals sensitive configuration data that you must pass directly to the rdkafka library, such as passwords. This parameter accepts settings in the same format as kafka_conf.

Values passed to this parameter are not logged or stored in system tables.

timeout

Integer number of seconds to wait for a response from the Kafka cluster.

=> SELECT KafkaListTopics(USING PARAMETERS brokers='kafka1-01.example.com:9092')
