Subject Message history and replay
Date Thu, 18 Jan 2007 15:52:47 GMT

Hi,

A quick question...

A common recovery scenario is requesting replay on a queue from a given,
known message, either by its ID or by something in the header. Its saves all
that mucking about with XA and makes recovery the normal way of system
startup rather then some exceptional case.

This means when a message has reached all its recipients it should never be
marked for removal from the durable message store. 

As a user, I would also like to control when messages get removed as part of
my end of day or even weekly processs, probably based on header property
selectors. 

I don't believe this is supported in AMQP in the wire protocol (nor perhaps
should it be) - is it maybe something that could be done via some
standardised command messages to a "replay" exchange?

Any thoughts on implementation difficulty? 

Regards,

Colin.
