            <title>[SERVER-41615] Transaction coordinator diagnostics should handle coordinator failover</title>
                <link>https://jira.mongodb.org/browse/SERVER-41615</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently, if a shard primary fails over while coordinating a two-phase commit, the new primary will create a new TransactionCoordinator to resume the two-phase commit, and the diagnostics it captures will be as if the new primary had coordinated the entire commit.&lt;/p&gt;

&lt;p&gt;The places with &lt;a href=&quot;https://github.com/mongodb/mongo/blob/b6ad5c431b8a1272617a3eff58872808afa53e31/src/mongo/db/s/transaction_coordinator.cpp#L87&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;TODO comments&lt;/a&gt; in transaction_coordinator.cpp should be updated in a way that makes it clear whether the coordinator was resumed after failover or not.&lt;/p&gt;</description>
