            <title>[SERVER-34885] Add ability to throttle or rate limit copyDatabase operation</title>
                <link>https://jira.mongodb.org/browse/SERVER-34885</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;It would be good if we could speed limit the copyDatabase operation.&#160; Currently when we do this the mongo database seems to try to do this operation as fast as possible which makes the server unusable for other operations.&#160;&#160;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;We have a multi tenanted setup with hundreds of databases running on the same database server.&#160; This copyDatabase operation essentially brings all customer environments to a standstill.&#160;&#160;&lt;/p&gt;</description>

&lt;p&gt;You can achieve similar semantics to copydb by using&#160;&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://docs.mongodb.com/manual/reference/program/mongodump/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodump&lt;/a&gt;&#160;&amp;#45;&amp;#45;archive &amp;#45;d &amp;lt;database-name&amp;gt;&#160;| &lt;a href=&quot;https://docs.mongodb.com/manual/reference/program/mongorestore/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongorestore&lt;/a&gt;&#160;&amp;#45;&amp;#45;archive&lt;/p&gt;

&lt;p&gt;There is a brief description of using Linux pipes to copy the output of one to the other (in the context of Atlas) &lt;a href=&quot;https://docs.atlas.mongodb.com/import/mongorestore/#pipe-behavior&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;&#160;but it will work with any two clusters.&lt;/p&gt;

&lt;p&gt;If you want to copy a database within the same instance renaming it, you can use mongodump piped to to mongorestore method with &lt;tt&gt;--nsFrom --nsTo&lt;/tt&gt;&#160;options to rename.&lt;/p&gt;</comment>

&lt;p&gt;What is copyDb being deprecated in favour of?&#160; I couldn&apos;t find any publically available documentation on this topic.&#160; Does the successor of copyDb have any rate limiting throttling capability?&#160; Thanks.&lt;/p&gt;</comment>
