[jira] [Commented] (MESOS-9120) Optimize range addition operation.

    [ https://issues.apache.org/jira/browse/MESOS-9120?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16643827#comment-16643827 ] 

Meng Zhu commented on MESOS-9120:
---------------------------------

After some more benchmarking, I think the existing implementation is more or less optimal at the current complexity. The above patch is more performant when there are thousands or tens of thousands of sub-ranges. Given that in practice, this is uncommon. I will leave the current code as is and close this ticket.

> MESOS-9086 made range subtraction operation faster than addition which shows room for improvement for addition.
