            <title>[DOCS-10803] Highlight renameCollection caveats</title>
                <link>https://jira.mongodb.org/browse/DOCS-10803</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;The renameCollection command says it is &quot;suitable for production environments:&lt;br/&gt;
 &lt;a href=&quot;https://docs.mongodb.com/manual/reference/command/renameCollection/#behavior&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/reference/command/renameCollection/#behavior&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;.. and then highlights two caveats that contradict this:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;renameCollection blocks all database activity for the duration of the operation.&lt;/li&gt;
	&lt;li&gt;renameCollection is not compatible with sharded collections.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;The most important warning is lurking below the example:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;This command obtains a global write lock and will block other operations until it has completed.&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;I think this should not be recommended for production environments and the warning on global lock should be prominently featured. An initial skim of the &quot;blocks all database activity&quot; point might suggest that this only blocks activity for the current database rather than globally.&lt;/p&gt;

&lt;p&gt;Note: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-15723&quot; title=&quot;Avoid G_X lock for rename_collection within database&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-15723&quot;&gt;&lt;del&gt;SERVER-15723&lt;/del&gt;&lt;/a&gt; will improve the lock granularity for renames within the same database, but renaming a collection between databases will still involve a global write lock while the data is copied to the target database.&lt;/p&gt;</description>
