ETL Signal. Each component can send signals. Trigger Transitions can listen to these signals. Signals are automatically generated:

start : When the component starts.
start_input : At the first row received by the component.
start_output : At the first row sent by the component.
no_input : At the end of the process, when no data is received.
stop : When the component is paused.
continue : When the component restarts after a pause.
end : When the component finishes its process.
error : When the component gives error.
