public KafkaMonitorIntegrationConnector()

Method Detail

initialize

public void initialize(String connectorInstanceId,
                       ConnectionProperties connectionProperties)

Initialize the connector.

Overrides:

initialize in class ConnectorBase

Parameters:

connectorInstanceId - - unique id for the connector instance - useful for messages etc

connectionProperties - - POJO for the configuration used to create the connector.

start

public void start()
           throws ConnectorCheckedException

Indicates that the connector is completely configured and can begin processing. This call can be used to register with non-blocking services.

Specified by:

start in interface org.odpi.openmetadata.governanceservers.integrationdaemonservices.connectors.IntegrationConnector

Overrides:

start in class ConnectorBase

Throws:

ConnectorCheckedException - there is a problem within the connector.

refresh

public void refresh()
             throws ConnectorCheckedException

Requests that the connector does a comparison of the metadata in the third party technology and open metadata repositories. Refresh is called when the integration connector first starts and then at intervals defined in the connector's configuration as well as any external REST API calls to explicitly refresh the connector. This method performs two sweeps. It first retrieves the topics from the event broker (Kafka) and validates that are in the catalog - adding or updating them if necessary. The second sweep is to ensure that all of the topics catalogued actually exist in the event broker.

Throws:

ConnectorCheckedException - there is a problem with the connector. It is not able to refresh the metadata.

disconnect

public void disconnect()
                throws ConnectorCheckedException

Shutdown kafka monitoring

Specified by:

disconnect in interface org.odpi.openmetadata.governanceservers.integrationdaemonservices.connectors.IntegrationConnector

Overrides:

disconnect in class ConnectorBase

Throws:

ConnectorCheckedException - something failed in the super class
