            <title>[SERVER-82072] Time-series collection creation does not perform shard version checks on buckets collection</title>
                <link>https://jira.mongodb.org/browse/SERVER-82072</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Creating a time-series collection on a sharded cluster forwards the command to the primary shard using the user-facing view namespace (which is inherently unsharded), meaning that even if a sharded buckets collection already exists that shard versioning information is not included in the request. When creating the buckets collection on the shard, we &lt;a href=&quot;https://github.com/mongodb/mongo/blob/fc174d081bdd6a5178cc888e6f0309d23504b4df/src/mongo/db/catalog/create_collection.cpp#L441&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;skip shard versions checks when acquiring the collection&lt;/a&gt; and then &lt;a href=&quot;https://github.com/mongodb/mongo/blob/fc174d081bdd6a5178cc888e6f0309d23504b4df/src/mongo/db/catalog/create_collection.cpp#L444-L452&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;return early if the collection already exists on that shard&lt;/a&gt;. There is a shard version check &lt;em&gt;after&lt;/em&gt; that, but at that point we already know that the collection doesn&apos;t exist on the shard (plus the shard version information provided with the request is for a different namespace, as previously noted).&lt;/p&gt;</description>
