            <title>[SERVER-55679] Remove wait for w:majority from donor shards generating minFetchTimestamp in resharding</title>
                <link>https://jira.mongodb.org/browse/SERVER-55679</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The PrimaryOnlyService framework code guarantees that a PrimaryOnlyService::Instance does all of its writes under the same replication term. This naturally leads to the monotonic writes property. The monotonic writes property is sufficient here because the DonorStateEnum::kDonatingInitialData update can only become majority-committed if the no-op oplog entry to generate the minFetchTimestamp had also become majority-committed. This makes &lt;a href=&quot;https://github.com/mongodb/mongo/blob/268ee9dad3b1fbebe7ffc74a86a2de6d644b996e/src/mongo/db/s/resharding/resharding_donor_service.cpp#L98-L100&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;waiting for w:majority here&lt;/a&gt; unnecessary. And waiting for w:majority can be problematic because the timestamp to be pinned can end up lagging behind the current oldest&amp;#95;timestamp value and therefore become ineligible for pinning.&lt;/p&gt;</description>
