Guaranteed delivery (GD) is a delivery mechanism that guarantees data is processed
from a stream to an adapter.
GD ensures that data continues to be processed when:
The ESP Server fails.
The destination (third-party server) fails.
The destination (third-party server) does not respond for a period of time.
Input adapters support GD using facilities provided by the external datasource to which
the input transporter connects.
Enabling Guaranteed Delivery for an Input Transporter
(Optional) Enable guaranteed delivery (GD) in a custom input transporter by implementing the com.sybase.esp.adapter.framework.event.AdapterRowEventListener interface, registering the GdAdapterEventListener class, and adding and setting the <GDMode> parameter to true for the EspPublisher or EspMultistreamPublisher.
