Method Detail

initialize

public void initialize(ConnectorContext ctx)

Description copied from class: Connector

Initialize this connector, using the provided ConnectorContext to notify the runtime of input configuration changes.

Overrides:

initialize in class Connector

Parameters:

ctx - context object used to interact with the Kafka Connect runtime

initialize

public void initialize(ConnectorContext ctx,
                       List<Map<String,String>> taskConfigs)

Description copied from class: Connector

Initialize this connector, using the provided ConnectorContext to notify the runtime of input configuration changes and using the provided set of Task configurations. This version is only used to recover from failures.

The default implementation ignores the provided Task configurations. During recovery, Kafka Connect will request an updated set of configurations and update the running Tasks appropriately. However, Connectors should implement special handling of this case if it will avoid unnecessary changes to running Tasks.

Overrides:

initialize in class Connector

Parameters:

ctx - context object used to interact with the Kafka Connect runtime

taskConfigs - existing task configurations, which may be used when generating new task configs to avoid churn in partition to task assignments

reconfigure

public void reconfigure(Map<String,String> props)

Description copied from class: Connector

Reconfigure this Connector. Most implementations will not override this, using the default implementation that calls Connector.stop() followed by Connector.start(Map). Implementations only need to override this if they want to handle this process more efficiently, e.g. without shutting down network connections to the external system.

Overrides:

reconfigure in class Connector

Parameters:

props - new configuration settings

validate

public Config validate(Map<String,String> connectorConfigs)

Description copied from class: Connector

Validate the connector configuration values against configuration definitions.

Overrides:

validate in class Connector

Parameters:

connectorConfigs - the provided configuration values

Returns:

a parsed and validated Config containing any relevant validation errors with the raw connectorConfigs which should prevent this configuration from being used.

version

public String version()

Description copied from interface: Versioned

Get the version of this component.

Returns:

the version, formatted as a String. The version may not be null or empty.

start

public void start(Map<String,String> props)

Description copied from class: Connector

Start this Connector. This method will only be called on a clean Connector, i.e. it has either just been instantiated and initialized or Connector.stop() has been invoked.

Specified by:

start in class Connector

Parameters:

props - configuration settings

taskClass

public Class<? extends Task> taskClass()

Description copied from class: Connector

Returns the Task implementation for this Connector.

Specified by:

taskClass in class Connector

taskConfigs

public List<Map<String,String>> taskConfigs(int maxTasks)

Description copied from class: Connector

Returns a set of configurations for Tasks based on the current configuration, producing at most maxTasks configurations.

Specified by:

taskConfigs in class Connector

Parameters:

maxTasks - maximum number of configurations to generate

Returns:

configurations for Tasks

stop

public void stop()

Description copied from class: Connector

Stop this connector.

Specified by:

stop in class Connector

config

public ConfigDef config()

Description copied from class: Connector

Define the configuration for the connector.

Specified by:

config in class Connector

Returns:

The ConfigDef for this connector; may not be null.
