            <title>[SERVER-54534] No need to wait for writeConcern on aborting a multi-document transaction</title>
                <link>https://jira.mongodb.org/browse/SERVER-54534</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;If a transaction aborts due to reasons other than an explicit abortTransaction command (e.g. writeConflict errors), we could still hit &lt;a href=&quot;https://github.com/mongodb/mongo/blob/bcd2d887611fc144f3fce31d9fc7d01628b99e61/src/mongo/db/service_entry_point_mongod.cpp#L142-L144&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this&lt;/a&gt; which would call &lt;tt&gt;setLastOpToSystemLastOpTime&lt;/tt&gt; and &lt;tt&gt;waitForWriteConcern&lt;/tt&gt; unnecessarily.&lt;/p&gt;

&lt;p&gt;There is also a weird behavior where if the same connection is used outside of transaction, abortTransction would also wait for writeConcern for the lastOp set by the same connection in previous writes done outside of the transaction (see &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b8cd0ef00f5ef5cf978317cf4cee16ac100c860b/jstests/replsets/transactions_wait_for_write_concern.js#L145-L147&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this test&lt;/a&gt;). This is because &lt;tt&gt;wasGlobalLockTakenForWrite&lt;/tt&gt; would always be true when aborting a transaction (either through abortTransction command or due to transaction errors).&lt;/p&gt;</description>
