            <title>[SERVER-70864] Get rid of fine grained scoped range deleter lock</title>
                <link>https://jira.mongodb.org/browse/SERVER-70864</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Purpose of this ticket is to simplify the scoped range deleter lock in order to solve all in once the problems listed in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-70322&quot; title=&quot;BalancerStatsRegistry inappropriately constructs ResourceId outside ResourceIdFactory&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-70322&quot;&gt;&lt;del&gt;SERVER-70322&lt;/del&gt;&lt;/a&gt;, &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-70340&quot; title=&quot;Range deleter can cause migration lock acquisition timeouts&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-70340&quot;&gt;&lt;del&gt;SERVER-70340&lt;/del&gt;&lt;/a&gt; and &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-70408&quot; title=&quot;Migrations for collection undergoing range deletion must not stall in v6.0&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-70408&quot;&gt;&lt;del&gt;SERVER-70408&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;The idea is to get rid of the fine grained locking because it has provoked more race conditions than advantages and because using it does not result in relevant performance improvements.&lt;/p&gt;

&lt;p&gt;We could provide a simple global scoped range deleter lock to be taken in different modes depending on the context.&lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Initializing balancer stats registry: &lt;b&gt;MODE_S&lt;/b&gt;&lt;/li&gt;
	&lt;li&gt;Initializing range deleter service:   &lt;b&gt;MODE_S&lt;/b&gt;&lt;/li&gt;
	&lt;li&gt;Updating the number of orphans:  &lt;b&gt;MODE_IX&lt;/b&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Only v6.1+ versions (to synchronize with range deleter service initialization)&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Creating a new range deletion task document    &lt;b&gt;MODE_IX&lt;/b&gt;&lt;/li&gt;
	&lt;li&gt;Unsetting the pending field                                 &lt;b&gt;MODE_IX&lt;/b&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Only v6.0+ versions (to synchronize with upgrade/downgrade)&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Setting the number of orphans on upgrade         &lt;b&gt;MODE_X&lt;/b&gt;&lt;/li&gt;
	&lt;li&gt;Unsetting the number of orphans on downgrade &lt;b&gt;MODE_X&lt;/b&gt;&lt;/li&gt;
&lt;/ul&gt;
