            <title>[SERVER-83423] [CQF] Store parameterized constants in optimizer metadata</title>
                <link>https://jira.mongodb.org/browse/SERVER-83423</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We need to store the constants associated with query parameters so that they can be given to the CE module. Storing them once in the metadata prevents us from needing to copy potentially large constants multiple times.&lt;/p&gt;</description>

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-83423&quot; title=&quot;[CQF] Store parameterized constants in optimizer metadata&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-83423&quot;&gt;&lt;del&gt;SERVER-83423&lt;/del&gt;&lt;/a&gt; Plumb query parameters through from OptPhaseManager to deriveCE()&lt;/p&gt;

&lt;p&gt;This patch add query parameters to the API of deriveCE(), so that the CE&lt;br/&gt;
modules can make use of constants when calculating selectivities of&lt;br/&gt;
predicates. This is crucial to having CE work with paramterization.&lt;/p&gt;

&lt;p&gt;This patch introduces the concept of QueryParameterMap which maps from&lt;br/&gt;
parameter ID to Constant. This map is populated during ABT translation&lt;br/&gt;
and then given to the OptPhaseManager.&lt;/p&gt;
