RabbitMQ publisher confirms

[ruwanmadhusanka]

Problem

If messages being sent to RabbitMQ are lost or dropped, we are unable to identify that they have been dropped.

Proposed Solution

Publisher confirms [1] in rebbitMQ which can be a facilitated mechanism to ensure reliability when publishing messages to a RabbitMQ exchange.
It would be better if we could get this feature in Micro Integrator.

Please refer to https://jack-vanlightly.com/blog/2018/9/10/how-to-lose-messages-on-a-rabbitmq-cluster as to why this feature is needed.

@ruwanmadhusanka https://github.com/wso2/wso2-axis2-transports/blob/v2.0.0-wso2v65/modules/rabbitmq/src/main/java/org/apache/axis2/transport/rabbitmq/RabbitMQConstants.java#L97 gives an indication that this is already supported. Please double check the validity of this issue.

In DRGSUB-197 it was discovered that this functionality already exists via the, currently still undocumented, property rabbitmq.publisher.confirms.enabled.

Hi @alienfs , @sajhak

The documentation has already been updated. Please find the documentation[1] for more details.

Thanks & Regards.

Hi @ruwanmadhusanka:

I see it is also written here:
https://apim.docs.wso2.com/en/4.1.0/reference/synapse-properties/transport-parameters/rabbitmq-transport-parameters/

I would suggest stating that the property is a boolean and thus requires a "true" or "false" value.

Regardless, this issue should be closed?
