Method Details

configure

public void configure(Map<String,?> configs)

Loads the cache and starts listening for directory events in directory specified in ConfluentConfigs.MULTITENANT_METADATA_DIR_CONFIG config. Adds the instance for the given broker session UUID, specified in KafkaConfig.BrokerSessionUuidProp, to the static instance map. The caller of this method must call close() when done to remove the instance from the static map. In addition to events in the directory, we are scheduling a full reload of the directory every MULTITENANT_METADATA_RELOAD_DELAY_MS to make sure nothing is missed

Parameters:

configs - broker configuration

Throws:

org.apache.kafka.common.config.ConfigException - if KafkaConfig.BrokerSessionUuidProp is not set, or ConfluentConfigs.MULTITENANT_METADATA_DIR_CONFIG is not set.

UnsupportedOperationException - if another instance of this class with the same broker session UUID was already configured.

start

isUp
