That's fine.
A design assumption should be to hold 5 days messages in the store. This is
more of a space than a performance issue.  People who need this can pay for
the disk.

That means that a queue size could be 500% of a day's activity.
If I were to use Qpid in serious business application, that could be 1
million 16KB messages.  About 100GB in total.

Looking forward, I'd imagine that the way disk and compute are going the
architecture will need to cater for large storage sizes.  Hitachi will
release a 1TB PC hard disk this quarter, and it won't cost a fortune.

Hi,

Re below - surely one key point in this discussion around replay thus far
has included the idea that delivered messages stay in the store. Thus, the
store (and queues) could potentially get far larger than otherwise .....
