            <title>[DOCS-13840] [SERVER] Database name case sensitivity possibly incorrect</title>
                <link>https://jira.mongodb.org/browse/DOCS-13840</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h2&gt;&lt;a name=&quot;Description&quot;&gt;&lt;/a&gt;Description&lt;/h2&gt;
&lt;p&gt;The docs for &lt;a href=&quot;https://docs.mongodb.com/manual/reference/limits/#Database-Name-Case-Sensitivity&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Database Name Case Sensitivity&lt;/a&gt; say: &quot;Since database names are case insensitive in MongoDB, database names cannot differ only by the case of the characters.&quot;&lt;/p&gt;

&lt;p&gt;I have not been able to verify this using the mongodb go driver or the mongo shell. An informal discussion with a member of the query team led me to believe this may not be correct. I&apos;m curious if this is platform dependent or possibly incorrect? I attempted to verify db name case-insensitivity using the go driver and mongo shell on a Mac.&lt;/p&gt;

                            <comment id="3444704" author="geert.bosch" created="Wed, 14 Oct 2020 18:17:16 +0000"  >&lt;p&gt;The issue for database names is that we have directory per DB, and some filesystems (such as on Windows, Mac) are case insensitive. We could have / should have properly normalized/escaped DB names, but we never did. So we check that we don&apos;t allow creation of two databases that only differ in name. Also on Windows we&apos;re more restrictive in allowed database names than on other systems.&lt;/p&gt;</comment>
                            <comment id="3444674" author="charlie.swanson" created="Wed, 14 Oct 2020 18:03:27 +0000"  >&lt;p&gt;I would be surprised if database names are case insensitive, I have never heard of that. It sounds like it has already been tested so I haven&apos;t done my own. Perhaps someone from execution could confirm or knows any historical context. &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=geert.bosch&quot; class=&quot;user-hover&quot; rel=&quot;geert.bosch&quot;&gt;geert.bosch&lt;/a&gt;] can you confirm or know anyone who could?&lt;/p&gt;</comment>
