            <title>[SERVER-69586] Make update/delete of range deletion document on recipient idempotent</title>
                <link>https://jira.mongodb.org/browse/SERVER-69586</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=jordi.serra-torrens%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;jordi.serra-torrens@mongodb.com&quot;&gt;jordi.serra-torrens@mongodb.com&lt;/a&gt; pointed out that there may be a very improbable but still relevant bug after the changes committed under &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-69555&quot; title=&quot;Range deletions must always be referred by `collUuid+range` rather than `migrationId`&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-69555&quot;&gt;&lt;del&gt;SERVER-69555&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;The migration coordinator is asking the recipient to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b1d33c08186ae0d6c8dae7f9531c652c2ece1730/src/mongo/db/s/migration_util.h#L207-L216&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;unset&lt;/a&gt; the &lt;tt&gt;pending&lt;/tt&gt; field (in case of commit) or &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b1d33c08186ae0d6c8dae7f9531c652c2ece1730/src/mongo/db/s/migration_util.h#L183-L187&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;delete&lt;/a&gt; the range deletion document (in case of abort).&lt;/p&gt;

&lt;p&gt;Since targeting is not done anymore by &lt;tt&gt;migrationId&lt;/tt&gt;, it may happen the following:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;An update/delete on the recipient succeeds, but the request gets  stuck in the network and is also retried after 1 hour.&lt;/li&gt;
	&lt;li&gt;After 1 hour, a new migration involving the same range may be happening, and the update/deletion would be wrongly applied.&lt;/li&gt;
&lt;/ul&gt;
