            <title>[SERVER-63880] [Retryability] Make resharding handle applyOps oplog entries with WouldChangeOwningShard sentinel noop entry</title>
                <link>https://jira.mongodb.org/browse/SERVER-63880</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-59186&quot; title=&quot;[API] Use internal transaction API for changing a document&amp;#39;s shard key logic&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-59186&quot;&gt;&lt;del&gt;SERVER-59186&lt;/del&gt;&lt;/a&gt;&#160;makes mongos use internal transactions to handle WouldChangeOwningShard update and findAndModify. As a result, mongos no longer uses the client txnNumber to run the transaction that handles the WouldChangeOwningShard error. To make a retry still fail with an IncompleteTransactionHistory error, &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-63366&quot; title=&quot;Basic retryability support for findAndModify WCOS with transaction API&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-63366&quot;&gt;&lt;del&gt;SERVER-63366&lt;/del&gt;&lt;/a&gt; introduced the notion of &lt;a href=&quot;https://github.com/mongodb/mongo/blob/7ad05d39663d30ee9f20afafd499905a165127f9/src/mongo/db/transaction_participant.cpp#L3092-L3101&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;WouldChangeOwningShard sentinel operation entry&lt;/a&gt;&#160;to&#160;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/7ad05d39663d30ee9f20afafd499905a165127f9/src/mongo/db/ops/write_ops_retryability.cpp#L281-L283&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;trigger to an IncompleteTransactionHistory error&lt;/a&gt;&#160;on retries. So applyOps oplog entries for retryable internal transactions can now contain a noop (i.e. no CRUD) operation, this is expected to lead to an error during resharding since it &lt;a href=&quot;https://github.com/mongodb/mongo/blob/7ad05d39663d30ee9f20afafd499905a165127f9/src/mongo/db/s/resharding/resharding_oplog_batch_preparer.cpp#L119-L123&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;doesn&apos;t expect&lt;/a&gt;&#160;to see a non CRUD operation in an applyOps oplog entry.&lt;/p&gt;</description>
