Hi guys, we are starting with kafka in our project. We are using version 0.8. I come from a traditional JMS MoM architecture, and some things are new to me.
One thing that I'm not getting is the mapping between partitions and number of threads. On a single consumer I can see the relationship but what happens when you have multiple consumers? So say, I have a topic and I have 5 instances of services that acts as consumers. On a traditional pub/sub I would have all 5 instances to consume the message right? Even if this topic only has one partition and now we have 5 threads (one per jvm instance) consuming it. Does this proceed? Just want to make sure if that is the expected behavior, from the docs it wasn't clear if its the number of threads per consumer, or the total number of threads around all clients to the topic.
