ConfigurableRequest the implementing class to (re)configure itself.
When configuration parameters are changed, they must be reflected by the component asap.
There are no thread safety guarantees on when configure might be called.
configure in interface Configurablepublic Sink.Status process() throws EventDeliveryException
SinkRequests the sink to attempt to consume data from attached channel
Note: This method should be consuming from the channel within the bounds of a Transaction. On successful delivery, the transaction should be committed, and on failure it should be rolled back.
process in interface SinkEventDeliveryException - In case of any kind of failure to
deliver data to the next hop destination.public void start()
LifecycleAwareStarts a service or component.
Implementations should determine the result of any start logic and effect
the return value of LifecycleAware.getLifecycleState() accordingly.
