            <title>[SERVER-71693] Exhaustive histogram creation testing</title>
                <link>https://jira.mongodb.org/browse/SERVER-71693</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We should have tests for histogram creation that test:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;mixed-type histograms (all types/ different type combinations) with different numbers of buckets&lt;/li&gt;
	&lt;li&gt;histograms that generate buckets with range values&lt;/li&gt;
	&lt;li&gt;histograms generated on a very large number of values&lt;/li&gt;
	&lt;li&gt;array and scalar variants of the above testing scenarios&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;As a note, work done in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-71310&quot; title=&quot;Validate histograms&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-71310&quot;&gt;&lt;del&gt;SERVER-71310&lt;/del&gt;&lt;/a&gt; may prove useful in ensuring that valid histograms are generated in all cases by maxdiff, but we may also want to hand-craft some small datasets that should generate a specific shape of maxdiff histogram and unit-test that this is in fact what we generate.&lt;/p&gt;</description>
