            <title>[SERVER-41222] Transaction history iterator shouldn&apos;t yield on next()</title>
                <link>https://jira.mongodb.org/browse/SERVER-41222</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Transaction iterator is used in SyncTail::multiApply() to fetch the oplog chain of unprepared transactions. However yielding doesn&apos;t support PBWM lock, which is held by sync tail. We don&apos;t need yielding when reading transaction history since it&apos;s always a point query.&lt;/p&gt;</description>

Does that sound good to you?&lt;/p&gt;</comment>
                            <comment id="2251237" author="siyuan.zhou@10gen.com" created="Fri, 17 May 2019 21:19:52 +0000"  >&lt;p&gt;This issue happen frequently on the linked BF ticket, I hope this can be fixed by RC0. Replication team can also take this ticket, however since the proposal of using NO_YIELD policy may conflict with the change stream support of large transaction POC, &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=justin.seyster&quot; class=&quot;user-hover&quot; rel=&quot;justin.seyster&quot;&gt;justin.seyster&lt;/a&gt; suggested to assign this to Query team for triage.&lt;/p&gt;</comment>
