            <title>[SERVER-37080] Implement tuneable batch size for chunk migrations</title>
                <link>https://jira.mongodb.org/browse/SERVER-37080</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-27725&quot; title=&quot;Use batch insert when migrating chunks&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-27725&quot;&gt;&lt;del&gt;SERVER-27725&lt;/del&gt;&lt;/a&gt; implemented batch inserts for chunk migrations, but for some workloads inserting a ~16MB batch can impact secondary read performance. This ticket would be to implement a tuneable parameter to control how many documents were inserted using the batch insert rather than inserting the entire batch at once.&lt;/p&gt;</description>
