What if a partition were described as a structured (ordered?) commit log, and a 
topic described as a collection of one or more partitions? In that way the 
hierarchy of these abstractions is clear, and it is also clear the properties 
of the partition are of course an aspect of its controlling topic.

IMHO, it has a co-relation with the previous statement: *The partitions in the 
log serve several purposes...*. So we described the log as data of the topic 
and partitions of the logs would be partitions of the topic's data.
