Hello Brock, A ’slave’ broker in the technical sense does not have active transport connectors, so clients are not able to process messages. The slave is used as a standby instance during a failure scenario for the master broker.
Perhaps you have a different setup? Keep in mind— maintaining message order across multiple brokers to end clients is virtual impossible to guarantee. If you need strict message ordering AND distribution across multiple brokers (aka partitioning) you may want to considert performing some sort of filtering or sorting of the message groups into separate queues.
