            <title>[SERVER-57482] Adaptively call wiredtiger_calc_modify</title>
                <link>https://jira.mongodb.org/browse/SERVER-57482</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When updating in wiredtiger record store, wiredtiger_calc_modify is called to attempt to get a diff for faster update. However, when it fails to calculate such a diff, the time goes wasted. For certain workload (e.g. time series), we found that the calculation rarely succeeds and slows down the updates. We would like to implement a general heuristic (not just for time series) to adaptively increase or decrease the frequency on attempting to do the calculation.&lt;/p&gt;

&lt;p&gt;After implementing the heuristic, the &quot;engineering solution&quot; for time-series in the linked ticket should be removed.&lt;/p&gt;</description>
