Btw, this was the email discussion we previously had about this with Vivek 
who did most of the work here...

Subject: [grouper-users] RE: [tier-api] grouper rabbitmq messaging

Im happy to do whatever Java messenging client someone wants me to.  Right 
now we have built-in, rabbitmq, activemq, and aws.  Is there another amqp 
server that someone is using that is not on that list that they will do 
grouper messenging with and is there a generic ampq java client that someone 
knows works with it and others?  Honestly, its not a lot of effort to 
implement the messenging interface with a specific client and I don't want to 
spend too much time figuring out why a generic client doesn't work or lose 
features that are specific to a messenging system.  Ok?  :)   Anyways, im 
happier with specific experience with clients and not wikis about how things 
should work in an ideal world if that makes sense :)  (no offense)

Thanks
Chris

AMQP and reference implementations are on the agenda for Wednesday's TIER 
API/Registry WG call.  See

The more I read, the more I think we have to do an evaluation of options 
here.  See, e.g. https://jira.spring.io/browse/AMQP-662

Note for Spring users: Spring-jms supports AMQP 1.0, while Spring-amqp 
supports AMQP 0.9.  See stackoverflow message from last week:

RabbitMQ does have a plug-in for AMQP 1.0 
(https://github.com/rabbitmq/rabbitmq-amqp1.0/blob/rabbitmq_v3_6_10/README.md 
).  Chris, what do you think? It would be much better to be on AMQP 1.0 if 
feasible.

Subject: [grouper-users] Re: [tier-api] grouper rabbitmq messaging

The reason the product keeps being specified is because the Wiki page for 
'Grouper Messaging with RabbitMQ' [1] talks about an integration which uses 
amqp-client-4.0.2.jar by RabbitMQ [2], which implements the AMQP 0.9.1 
protocol [3]. Although RabbitMQ promulgated the AMQP spec first, the later 
version AMQP 1.0 is not compatible, and that's the version that has seen 
adoption in other messaging products. Therefore, this Grouper integration is 
indeed compatible with RabbitMQ, but essentially no other messaging product, 
making the distinction important.

I am excited about this capability.  From the conversations I have 
participated this work was supposed to be about supporting the AMQP protocol 
and not specifying the product - RabbitMQ.  AMQP is supported by nearly all 
the popular messaging products.  I think it would be wise to go with AMQP 
support for Grouper and not specify the product.

Yes.. I will start working on it

Ok, so we will just have a separate activeMq project?

 

Thanks!

Hi Chris,

 

I did some more research about amqp.

 

Our RabbitMQ connector is amqp as I followed the steps from this tutorial: https://www.rabbitmq.com/tutorials/tutorial-one-java.html and they say that it's amqp connector. But, I don't think we will be able to reuse the code though since the client APIs are different. For ActiveMQ, we will need to configure some properties to use amqp protocol as mentioned here: http://activemq.apache.org/amqp.html 

 

So my understanding is that amqp defines more granular level details which brokers/clients have to implement internally but not the APIs.

 

Thanks,

Vivek

Vivek,

 

If the rabbitmq messenging connector is not amqp, then maybe the next project should be grouper-messaging-aqmp?

 

Then we can see if that works against rabbitmq and activemq?

 

Thanks

Chris
