            <title>[SERVER-76818] Separate secondary oplog application storage transactions with many index writes</title>
                <link>https://jira.mongodb.org/browse/SERVER-76818</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;If applying an oplog entry requires many index writes, it can cause write conflicts (due to cache pressure) and slowness, especially as the size of the storage transaction increases. There&apos;s no need to apply the entire oplog entry in one storage transaction (we currently split up prepared transactions into multiple storage transactions, for example). I&apos;m not sure the best way to determine when to split up a storage transaction.&lt;/p&gt;</description>

Ideally, we would only do this when the storage engine is actually under cache pressure.&lt;/p&gt;</comment>
