Description:
===========
The RVCMQ transport (i.e. a constellation of RVCM listeners using DQ transports) can be used without any problems though there is a caveat. The actual communication between the publisher and the subscribers will no longer be certified communication and will be relegated to reliable communication even though the subscribers are using RVCMQ transports. This is because being a reliable sender, it will not have a CM delivery agreement with the listeners and will not have the ability to keep messages pending in its ledger file. In case of a network congestion/high resource usage, there is a possibility of experiencing data loss. With the above configuration, the only advantage that the applications have over basic reliable communication is achieving load balancing via the distributed queue.
