public class DuckDBDatabaseIntegrationConnector
extends DynamicIntegrationConnectorBase

DuckDBDatabaseIntegrationConnector catalogs a single DuckDB database (an embedded ".duckdb" file, or an in-memory ":memory:" session). DuckDB has no server tier, so - unlike the equivalent connectors for the other database technologies supported by Egeria - there is no server-level hand-off logic here: each catalog target is processed directly by a DuckDBDatabaseCatalogTargetProcessor.

Constructor Details

DuckDBDatabaseIntegrationConnector

public DuckDBDatabaseIntegrationConnector()

Method Details

start

public void start()
           throws ConnectorCheckedException,
UserNotAuthorizedException

Indicates that the connector is completely configured and can begin processing.

Specified by:

start in interface IntegrationConnector

Overrides:

start in class IntegrationConnectorBase

Throws:

ConnectorCheckedException - the connector detected a problem.

UserNotAuthorizedException - the connector was disconnected before/during start

getNewRequestedCatalogTargetSkeleton

public RequestedCatalogTarget getNewRequestedCatalogTargetSkeleton(CatalogTarget retrievedCatalogTarget,
 CatalogTargetContext catalogTargetContext,
 Connector connectorToTarget)
                                                            throws ConnectorCheckedException

Create a new catalog target processor (typically inherits from CatalogTargetProcessorBase).

Specified by:

getNewRequestedCatalogTargetSkeleton in interface CatalogTargetFactory

Specified by:

getNewRequestedCatalogTargetSkeleton in class DynamicIntegrationConnectorBase

Parameters:

retrievedCatalogTarget - details of the open metadata elements describing the catalog target

catalogTargetContext - specialized context for this catalog target

connectorToTarget - connector to access the target resource

Returns:

new processor based on the catalog target information

Throws:

ConnectorCheckedException - a problem with setting up the catalog target.

disconnect

public void disconnect()
                throws ConnectorCheckedException

Free up any resources held since the connector is no longer needed.

Specified by:

disconnect in interface IntegrationConnector

Overrides:

disconnect in class IntegrationConnectorBase

Throws:

ConnectorCheckedException - the connector detected a problem.
