------------------------------------------------------------------
Hi, I am sorry, but traversing will be limited to the connections that will
actually be expired, so there is no traversing of non-expiring connections! I
do agree on the other hand that it will mean polling the first element until it
expires, but I think it is a small price to pay to have the requirement exactly
as intended. If we want to protect brokers from becoming zombies, this is a
different concern I feel. [~junrao], [~jkreps], what do you think?
Say the server hold 100K connections. Say 100 connections are not used in the
last 10 minutes.
What the program does (or I will make sure it does) is just iterate through the
first 101 connections, the first 100 will be expired and it will stop at number
101.
I think this is an exact achievement of expected behavior of the jira task, as
intended, and there is no performance penalty to that really!
