            <title>[SERVER-64505] Add workload where application threads perform eviction</title>
                <link>https://jira.mongodb.org/browse/SERVER-64505</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Having application threads perform eviction is WT&apos;s way of applying backpressure to the application. This workload should demonstrate WT resource exhaustion in the form of application threads running eviction.&lt;/p&gt;

&lt;p&gt;Some points about eviction:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Above 5% (dirty_target): worker threads evict. Above 20% (dirty_trigger): application threads start evicting&lt;/li&gt;
	&lt;li&gt;Update_trigger = min(eviction_trigger (80), dirty_trigger / 2)&lt;/li&gt;
	&lt;li&gt;Update_target = dirty_trigger / 2&lt;/li&gt;
