            <title>[SERVER-69478] remove unnecessary copy in TransactionParticipant::commitUnpreparedTransaction()</title>
                <link>https://jira.mongodb.org/browse/SERVER-69478</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2b958166154c99dc554591d57ce44caee35cb446/src/mongo/db/transaction/transaction_participant.cpp#L1815&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;copy operation&lt;/a&gt; can be replaced with a mutable reference to the container of replication operations.&lt;/p&gt;

&lt;p&gt;Compare with this usage of &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2b958166154c99dc554591d57ce44caee35cb446/src/mongo/db/transaction/transaction_participant.cpp#L1781&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;TransactionParticipant::retrieveCompletedTransactionOperations()&lt;/a&gt; in TransactionParticipant::prepareTransaction()|https://github.com/mongodb/mongo/blob/2b958166154c99dc554591d57ce44caee35cb446/src/mongo/db/transaction/transaction_participant.cpp#L1600].&lt;/p&gt;

&lt;p&gt;Storing a mutable reference to the completed operations is preferable because the caller is responsible for clearing the in-memory operations using &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2b958166154c99dc554591d57ce44caee35cb446/src/mongo/db/transaction/transaction_participant.cpp#L1799&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;clearOperationsInMemory&lt;/a&gt;. Additionally, the OpObserver interfaces are declared to accept a pointer to the vectory of &lt;tt&gt;ReplOperations&lt;/tt&gt;.&lt;/p&gt;</description>
