            <title>[SERVER-24941] Retain previous cursor position(s) on server to enable getMore retrying</title>
                <link>https://jira.mongodb.org/browse/SERVER-24941</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This would enable a driver (or replica set node via the internal client) to retry a getMore that got interrupted by timeout or network error, without needing to reestablish the cursor position with a new find query.&lt;/p&gt;

&lt;p&gt;The project requires a change to the format of the getMore command as well as internal changes to the way we track cursors on the server.   &lt;/p&gt;

&lt;p&gt;There may be some design complications regarding aggregation in particular.&lt;/p&gt;</description>

Without this ticket, a transient network error during a collection clone forces us to restart the collection clone from scratch, because we have no way to specify where we&apos;re picking up from.&lt;/p&gt;</comment>
