Constructor Details

KafkaTopicCatalogTargetProcessor

public KafkaTopicCatalogTargetProcessor(CatalogTarget template,
 CatalogTargetContext catalogTargetContext,
 Connector connectorToTarget,
 String connectorName,
 AuditLog auditLog)
                                 throws ConnectorCheckedException,
UserNotAuthorizedException

Copy/clone constructor

Parameters:

template - object to copy

catalogTargetContext - specialized context for this catalog target

connectorToTarget - connector to access the target resource

connectorName - name of this integration connector

auditLog - logging destination

Throws:

ConnectorCheckedException - problem connecting to topic

UserNotAuthorizedException - the connector was disconnected before/during start

Method Details

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.

Specified by:

refresh in class CatalogTargetProcessorBase

Throws:

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

refreshEventBroker

public void refreshEventBroker(String targetRootURL,
 String templateGUID,
 String templateQualifiedName)
                        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 the topics catalogued actually exist in the event broker.

Parameters:

targetRootURL - URL to the Kafka Broker

templateGUID - optional template to use when creating new topics

templateQualifiedName - qualifiedName for template - only set if templateGUID is set

Throws:

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