            <title>[SERVER-43817] Foreground collection validation cmd should periodically yield cursors to release snapshots and minimize cache pressure</title>
                <link>https://jira.mongodb.org/browse/SERVER-43817</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In v4.2 we created cursors as needed, so we would create a cursor to scan an entire index or collection table.&lt;/p&gt;

&lt;p&gt;In v4.4, we now create all cursors up front and reuse them errors are found to run the second phase (same as the first phase except saving more information). So rather than holding a snapshot for the duration of a single table scan, we could end up holding a snapshot open for 3x (say one collection scan and two index scans), or 6x (if the corruption was found and the second phase runs all the validation again).&lt;/p&gt;</description>
