Matthias,<br> Setting the "ttl" on the publisher queue does work fine when the consumer also declares the queue with 'ttl' (using Java client tested)<br><br><div align="left">Is it necessary for declaring the consumer queue to hold the configuration of ttl? My requirement is to drop the published messages which are older than X secs. Is there are way to achieve this using a Java publisher and C++ consumer?
