            <title>[DOCS-3456] mongodb tools and clients in sharded environment for 2.6 need to be updated to new bulk write operations to avoid performance degradation</title>
                <link>https://jira.mongodb.org/browse/DOCS-3456</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;We currently &lt;a href=&quot;http://docs.mongodb.org/master/release-notes/2.6-compatibility/#write-method-acknowledgements&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;advise customers&lt;/a&gt; that mongodb tools that do bulk ingestion using fire&amp;amp;forget with occasional getLastError need to be updated to use the new bulk api to avoid a performance degradation.&lt;/p&gt;

&lt;p&gt;Client applications coded in a similar manner using any driver (not just mongodb tools) in a sharded environment will see a similar performance degradation until they update the app to use the new bulk write operations, but I don&apos;t think we advise customers of that. See &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-14003&quot; title=&quot;2.6 mongos does not support overlapped writes at w:0&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-14003&quot;&gt;&lt;del&gt;SERVER-14003&lt;/del&gt;&lt;/a&gt; for some numbers for one such tool (mongorestore).&lt;/p&gt;</description>
