[Design of Messaging on JBoss (Messaging/JBoss)] - Re: QueueBrowser semantics

by timfox

I have refactored so the channel no longer maintains deliveries. This has furthered simplified things a lot and removed a whole area that was prone to race conditions. This of course results in a change to the semantics of queue browsing as discussed here.

The router is not really pertitent to this discussion which is about how messages get from a ServerConsumerEndpoin to the client side consumer. The router is just the thing that routes the message from the queue to the ServerConsumerEndpoint. anonymous wrote : | | Is the "server side representation" of the consumer the same as the "channel" in the JBoss Messaging architecture? No, the channel is the queue. The "server side representation" is the ServerConsumerEndpoint.

anonymous wrote : The server receives the flow rate change (0) and stops sending messages. The client consumes the backlog and when the number remaining reaches bufferSize / 2 it sends another flow rate change message to the server with a +ve value. | By server in the previous quote is this the router or the server side representation of the consumer? For example - if I had two consumers, and one is "backed up" and has sent a flow rate change (0). Will the round robin router continue to select the server side representation of this consumer? Or conversely, will the router be told this consumer is unavailable and temporarily stop selecting it? Is the "server side representation" of the consumer the same as the "channel" in the JBoss Messaging architecture?

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Streamlined delivery of messages to consumer

by timfox

So, basically what happens is this: The queue may have many consumers. When delivery occurs, the queue will select one of those consumers baside on the implementation of Router that is being used with the queue. The default implementation round robins between the consumers. Once the server side representation of the consumer has the message, it then needs to send it to client side. This works as described in the first post on this thread.

[Design of JBossCache] - Re: Serialization Compatibility Tests

by bela＠jboss.com

Most of the JGroups exceptions are meaningless, because JGroups doesn't use Java serialization anyways. I know that some JGroups exceptions *might* get serialized when used with method calls, but I don't see any of them in the output. Manik ?

Currently, the default policy is to round robin between all available consumers, but this has nothing to do with how we deliver messages to the client side.
