            <title>[SERVER-49894] Have resharding oplog fetcher resume from &apos;ts&apos; component of largest _id inserted</title>
                <link>https://jira.mongodb.org/browse/SERVER-49894</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The largest _id value in the config.localReshardingOplogBuffer.&amp;lt;existingUUID&amp;gt;.&amp;lt;donorShardId&amp;gt; collection should be used with {$match: {ts: {$gte: &amp;lt;resume oplog buffer _id.ts&amp;gt;}}} to resume. Properties to ensure are being tested:&lt;/p&gt;

&lt;ol&gt;
	&lt;li&gt;The oplog fetcher for resharding must not trigger a duplicate key error when resuming.&lt;/li&gt;
	&lt;li&gt;The oplog fetcher for resharding must not miss a document when resuming.&lt;/li&gt;
&lt;/ol&gt;
