David,

Is this feature in the roadmap for Sandesha2? What I am looking for is
something like JMS client ack.

Re: In-order processing

[David Illsley <da...@gmail.com>]

Not at the moment - it would be a pretty substantial change to the way
Sandesha2 works, and it's not the way many/most people want to use
one-way RM. In general, the RM protocol is hidden from the application
code - application authors generally just want to know that the
message they sent will be received, or that the message they have
received isn't a duplicate.
Can I suggest you use a 2-way operation to get the 'processing
complete' notification in the application layer?
Cheers,
David
