The specification defines durability, transactions, etc. the 0-10 specification also defines the fail-over handlers etc, for client interop which is used to in our Active-Active cluster implementation. What implementation is provided for these abilities in the spec is up to the implementer.

Have you given the Qpid Active-Active cluster a spin yet? did you know we had one.. i.e. we can do full Active Active clustering out the box with the C++ broker. it add about .35ms round trip latency on latencytest to keep a 4 node A-A cluster fully in sync Carl. Andrew Wright wrote: Yes,

Hi, I can give you a brief overview, and I'm sure that others (particularly the C++-ers) will add to this reply. Fundamentally, it's all about choice. Our project seeks to provide a range of client & broker implementations of the AMQP specification (and JMS for the Java elements) from which our u

Hi, I'm new to Qpid and have been following the threads and reading up on the docs for some time. I'm trying to decide on the brokers to be used for a private project and have this doubt. Why are multiple brokers that bring with them additional compatibility requirements being developed by QPID ?

See what you mean, thanks. The Qpid roadmap shows 0-10 implementation on the Java broker as one of our next big ticket deliveries. This would mean that the C++ client could again interop with the Java broker. On the C# front, we are discussing on the dev list the strategic solution going forward,

Yes, that's right. We're looking at in-memory replicated clustering technologies (eg. Terracotta/Coherence etc) in an active-active style setup. Cheers, Andrew On 28 Jan 2009, at 23:44, Robert Greig wrote: 2009/1/22 Andrew Wright : Background: we're examining ways to get reliable app-leve
