            <title>[SERVER-84399] Collscan benchmarks - extend existing projection tests to run with cardinalities</title>
                <link>https://jira.mongodb.org/browse/SERVER-84399</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Although there are a lot of benchmarks with varying projection types and complexity, all are over relatively small collections. In mongo-perf:&lt;/p&gt;

&lt;p&gt;WideProjectionTopLevelField (inclusion, exclusion, 9 projections, 10K documents)&lt;/p&gt;

&lt;p&gt;WideProjectionNestedField (nested field inclusion, exclusion, 9 projections)&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;For all of the bellow: single projection with dotted path of length 3 or 6, 10K documents:&lt;/p&gt;

&lt;p&gt;FindExclusion.ProjectionDottedField.SinglePathThreeComponentsNestedArraysOfSizeFive&lt;/p&gt;

&lt;p&gt;FindExclusion.ProjectionDottedField.SinglePathThreeComponents&lt;/p&gt;

&lt;p&gt;FindExclusion.ProjectionDottedField.SinglePathThreeComponentsNestedArraysOfSizeOne&lt;/p&gt;

&lt;p&gt;FindExclusion.ProjectionDottedField.SinglePathSixComponentsNestedArraysOfSizeOne&lt;/p&gt;

&lt;p&gt;FindExclusion.ProjectionDottedField.SinglePathSixComponentsNestedArraysOfSizeFive&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;FindProjectionThreeFields (3 projections, 100 docs)&lt;/p&gt;

&lt;p&gt;ProjectInclude_CollScan_LS ( 8 projections, 10-field 100K documents)&lt;/p&gt;

&lt;p&gt;ProjectInclude_CollScan_LL (8 projections, 23-field 100K documents)&lt;/p&gt;

&lt;p&gt;ProjectExclude_CollScan_LL (8 projections, 23-field 100K documents)&lt;/p&gt;

&lt;p&gt;ProjectNoExpressions_CollScan_LS( 8 projections with renaming of fields, 10-field 100K)&lt;/p&gt;

&lt;p&gt;ProjectNoExpressions_CollScan_LL( 8 projections with renaming of fields, 23-field 100K)&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;We will need to extend the existing mongo-perf tests to run for three different cardinalities: 100/1000, 10K/100K, and 1M documents. The small cardinality collections are useful to emphasize the optimization time in the metrics.&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;For queries over 10K/100K add cardinalities of 100 and 1M documents.&lt;/li&gt;
	&lt;li&gt;For queries over 100 documents add cardinalities of 10K and 1M documents.&lt;/li&gt;
&lt;/ul&gt;
