| quality of service (BC-XI) |
Attribute of message that enables the sender to define how this message is to be delivered.
The following qualities of service are supported:
BE (Best Effort):
The message is sent synchronously. The sender waits for a response before continuing processing.
EO (Exactly Once):
The message is sent asynchronously. The sender does not wait for a response before continuing processing. This quality of service guarantees that the message will be delivered and processed exactly once.
EOIO (Exactly Once In Order):
The message is sent asynchronously. Messages with the same queue name are delivered in the order in which the sender sent them.
