            <title>[SERVER-82838] ReshardingOplogApplier uses {w: &quot;majority&quot;, wtimeout: 60000} write concern when persisting resharding oplog application progress</title>
                <link>https://jira.mongodb.org/browse/SERVER-82838</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The PersistentTaskStore class &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4fda0a1e55e945ca1581f6e114298d88be610213/src/mongo/db/s/resharding/resharding_oplog_applier.cpp#L291-L294&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;called by the ReshardingOplogApplier&lt;/a&gt; &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4fda0a1e55e945ca1581f6e114298d88be610213/src/mongo/db/persistent_task_store.h#L128&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;uses WriteConcerns::kMajorityWriteConcernShardingTimeout when no argument is provided&lt;/a&gt;. The {w: &quot;majority&quot;, wtimeout: 60000} write concern can lead resharding to fail with an operation&amp;#45;fatal error due to the write concern not being satisfied quickly enough. Furthermore, there is no requirement for the ReshardingOplogApplier to have its current batch become majority&amp;#45;committed before moving on to process the subsequent batch. This is because the new primary of the recipient shard &lt;a href=&quot;https://github.com/mongodb/mongo/blob/4fda0a1e55e945ca1581f6e114298d88be610213/src/mongo/db/s/resharding/resharding_oplog_applier.cpp#L249-L251&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;will resume resharding batch application from wherever its local state left off from&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;The ReshardingOplogApplier should instead use {w: 1} for its write concern (&lt;a href=&quot;https://github.com/mongodb/mongo/blob/4fda0a1e55e945ca1581f6e114298d88be610213/src/mongo/db/s/resharding/resharding_recipient_service.cpp#L1344-L1348&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;for example&lt;/a&gt;).&lt;/p&gt;</description>
