comment design for buffering or queuing data streams to replace database
What I'm wondering about message queues is if they have the ability to prevent certain messages being read. eg: process 1 reads a message(m1) from device A, process 2 shouldn't be allowed to read any message from device A before process 1 has completed its work on message(m1), but should be allowed to read a message from a different device. Sort of locking some messages in the queue.

comment design for buffering or queuing data streams to replace database
@Frank - we do need to persist the data and have tried putting the data in memory but wanted to be able to process the data we've read on different machines as even multiple processes on the same machine aren't always fast enough, so need something that can cross app domains - a WCF service approach may work though.

Could you let us know what language you are developing in. The tools available in different languages can change the choices you make in designing something like this.
