nicu marasoiu commented on KAFKA-1282:
--------------------------------------
To make the ~O(1) cost of "traversing" more clear, typically only the first
element in the linked list is accessed, and it will typically be used in the
last 10 minutes, and in this case nothing happens anymore. Of course, this is
if the low volume topics do not generate many connections, which they won't,
with this cleaning up in place. And I am checking now that map() and the rest
are lazy, or else for sure I can make so that only the relevant "prefix/first"
part of the collection is iterated, typically first element only.
