public ExactlyOnceSupport exactlyOnceSupport(Map<String,String> connectorConfig)
For backwards compatibility, the default implementation will return
null, but connector authors are
strongly encouraged to override this method to return a non-null value such as
connectorConfig- the configuration that will be used for the connector.
ExactlyOnceSupport.SUPPORTEDif the connector can provide exactly-once support with the given configuration, and
ExactlyOnceSupport.UNSUPPORTEDif it cannot. If this method is overridden by a connector, should not be
null, but if
null, it will be assumed that the connector cannot provide exactly-once semantics.
public ConnectorTransactionBoundaries canDefineTransactionBoundaries(Map<String,String> connectorConfig)
Connector.start(Map), only when the runtime supports exactly-once and the connector configuration includes
This method need not be implemented if the connector implementation does not support defining transaction boundaries.

ConnectorTransactionBoundaries.SUPPORTEDif the connector will define its own transaction boundaries, or
ConnectorTransactionBoundaries.UNSUPPORTEDotherwise; may never be
null. The default implementation returns
