            <title>[SERVER-28884] CollectionRangeDeleter track deletions more reliably</title>
                <link>https://jira.mongodb.org/browse/SERVER-28884</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In current code, each metadata version has provisioned one range to delete when it is retired.  Registering a second range would require copying the metadata to a new version (if there is no other event that required the copy), a potentially expensive operation.  Keeping a list of ranges for each metadata version would simplify the code and avoid otherwise-unnecessary metadata copying.&lt;/p&gt;

&lt;p&gt;Furthermore, the event-managing code has a race in which a deletion could fail while the requester is not waiting, resulting in the failure not being reported to the requester, and then, possibly, in-migration to a range currently occupied.&lt;/p&gt;

&lt;p&gt;Solving this requires plumbing range deletion event notification through more levels of interface.&lt;/p&gt;</description>
