Method Detail

configure

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

Creates a consumer for the LKC metadata topic (named in the ConfluentConfigs.CDC_LKC_METADATA_TOPIC_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.

Specified by:

configure in interface org.apache.kafka.common.Configurable

Overrides:

configure in class io.confluent.kafka.multitenant.CommonTopicBasedPhysicalClusterMetadata<KafkaLogicalClusterMetadata>

Parameters:

configs - broker configuration

Throws:

org.apache.kafka.common.config.ConfigException - if KafkaConfig.BrokerSessionUuidProp is not set, or ConfluentConfigs.CDC_LKC_METADATA_TOPIC_CONFIG is not set, or ConfluentConfigs.CDC_TOPIC_LOAD_TIMEOUT_MS_CONFIG is not set, or unable to monitor the SSL certificates on disk.

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

getSessionUuid

protected String getSessionUuid(Map<String,?> configs)

Specified by:

getSessionUuid in class io.confluent.kafka.multitenant.CommonTopicBasedPhysicalClusterMetadata<KafkaLogicalClusterMetadata>

getStartSensor

protected org.apache.kafka.common.metrics.Sensor getStartSensor()

Specified by:

getStartSensor in class io.confluent.kafka.multitenant.CommonTopicBasedPhysicalClusterMetadata<KafkaLogicalClusterMetadata>

getEndToEndSensor

protected org.apache.kafka.common.metrics.Sensor getEndToEndSensor()

Specified by:

getEndToEndSensor in class io.confluent.kafka.multitenant.CommonTopicBasedPhysicalClusterMetadata<KafkaLogicalClusterMetadata>

getTopicConfig

protected String getTopicConfig()

Specified by:

getTopicClientId

protected String getTopicClientId(Map<String,?> configs)

Specified by:

startLog

protected void startLog()

Specified by:
