            <title>[SERVER-74772] Make analyzeShardKey command include all records in the monotonicity check</title>
                <link>https://jira.mongodb.org/browse/SERVER-74772</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Due to performance considerations, &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-68753&quot; title=&quot;Make analyzeShardKey command calculate metrics about the monotonicity&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-68753&quot;&gt;&lt;del&gt;SERVER-68753&lt;/del&gt;&lt;/a&gt; made it such that when multiple record ids have the same shard key value, &lt;a href=&quot;https://github.com/mongodb/mongo/blob/a9684a6176388f095a6a2b7857c042a89bf56530/src/mongo/db/s/analyze_shard_key_cmd_util.cpp#L478&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;only the id for one of the records&lt;/a&gt; is added to the list of record ids to calculate the coefficient coefficient for. This may be good for performance to some extent since it decreases the number of data points in the correlation coefficient calculation. However, as shown in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-74338&quot; title=&quot;Add concurrency workload that runs configureQueryAnalyzer and analyzeShardKey commands&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-74338&quot;&gt;&lt;del&gt;SERVER-74338&lt;/del&gt;&lt;/a&gt;, it has a non-negligible impact on the accuracy of the check.&#160;&#160;&lt;/p&gt;</description>
