mqtt subscription information not shared across network of brokers
Hi,
I am using activemq-5.10-SNAPSHOT codebase for mqtt. I tried the
following scenario with 2 broker network ( with
staticallyIncludedDestination ). the persistence store is not shared
between these two brokers.
Scenario 1:
client c1 ( clientid1) connects to broker A, publishes to topic A with
cleansession = false
client c2 ( clientid2) connects to broker B, subscribes to topic A with
cleansession = false
In this scenario, c1 receives message sent by c2 as expected.
Scenario 2:
client c1 publishes to topic A on broker A
client c2 now connects to broker A with cleansession=false. In this
case, no messages are received by c2.
per mqtt , if a client has set clean session as false, it should be auto
subscribed to topics which were subscribed already.
Please, can you let me know whether subscription information are
propagated between brokers so that a client connecting to either of the
broker receives the message
Thanks,
nl

Can you make a test case ?
I can check it for you. We implemented MQTT network of brokers but never
came across the problem. ( It was KahaDB though.)
