            <title>[SERVER-59833] Expand WT config fuzzing in mongod for collections and indexes</title>
                <link>https://jira.mongodb.org/browse/SERVER-59833</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Expand the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/buildscripts/resmokelib/mongod_fuzzer_configs.py&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongod config fuzzer&lt;/a&gt; to modify some of the following WT tunables for collections and indexes:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;memory_page_max&lt;/li&gt;
	&lt;li&gt;split_pct&lt;/li&gt;
	&lt;li&gt;internal_page_max&lt;/li&gt;
	&lt;li&gt;leaf_value_max&lt;/li&gt;
	&lt;li&gt;prefix_compression&lt;/li&gt;
	&lt;li&gt;block_compressor&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;This aims to expand test coverage over certain edge cases and unobservable behaviors inside WiredTiger.&lt;/p&gt;</description>
