Hi,
Yes my consumer application works like below
1. Reads how many workers are required to process each topics from
properties file
2. As many threads are spawned as there are workers mentioned in
properties file, topic name is passed to this thread. FixedThreadPool
implementation is used.
3. Each worker thread initializes one consumer object and subscribes to
given topic. Consumer group is simply <topic-name>-consumer. So if my topic
bulk-email, then consumer group for all those threads is bulk-email-consumer
4. Once this is done, inside an infinite while loop consumer.poll(100)
method keeps running. So this application is a daemon. Shuts down only when
server shuts down or in case of kill command.
I have configured session.timeout.ms in consumer properties. I haven't done
anything about zookeeper timeout. Is it required now? Since consumer
accesses only the brokers.
