> We've tried to use the concepts of "topic subscription" and "partition assignment" to distinguish between the old "high-level" and "simple" use cases, but the javadoc is not very clear about this (e.g. there is still a section titled "Subscribing to Specific Partitions"). Additionally, the section on consumer groups is a little hard to follow in regard to the notion of a group subscription.
