Description
Resolution:
Bridge destinations are processed before sending the response to the publisher. Therefore, with persistent delivery mode, if one has 10 outputs of a bridge, all 10 will be processed before the publisher is informed. This is true regardless of the bridge configuration, topic-topic, topic-queue, etc.
In terms of exception on the publisher side:
- If reliable delivery mode is used then there will be no exception because the EMS server never informs the publisher of the outcome.
- If the messages are non-persistent:
- if authorization is disabled then there will be no exception because the EMS server never informs the publisher of the outcome
- if authorization is enabled the publisher is informed of the outcome.
- If the messages are persistent the publisher is informed of the outcome.
