            <title>[SERVER-56108] [ephemeralForTest] view creation fails with NamespaceExists error if WUOW throws WCE at commit time</title>
                <link>https://jira.mongodb.org/browse/SERVER-56108</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The view creation logic currently depends on the WriteUnitOfWork committing successfully after calling &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8b9167a79df87ee0b0c5b761108cae6a1a232050/src/mongo/db/views/view_catalog.cpp#L542&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ViewCatalogWriter::commit()&lt;/a&gt;. The issue here is that it is possible for the ephemeralForTest RecoveryUnit implementation to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8b9167a79df87ee0b0c5b761108cae6a1a232050/src/mongo/db/storage/ephemeral_for_test/ephemeral_for_test_recovery_unit.cpp#L67&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;throw a WriteConflictException while committing&lt;/a&gt;. The WiredTiger RecoveryUnit does not have this behavior (as far as I know).&lt;/p&gt;

&lt;p&gt;A view creation under the ephemeralForTest storage engine that fails in this manner will encounter an inconsistent ViewCatalog on the second iteration of the WriteConflictException retry loop, leading to the NamespaceExists error.&lt;/p&gt;</description>
