            <title>[SERVER-85006] Handle variable interval boundaries in interval intersection</title>
                <link>https://jira.mongodb.org/browse/SERVER-85006</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;WRITING-8202 implements interval intersection when interval boundaries are constants.&lt;/p&gt;

&lt;p&gt;This task should extend the intersection logic to handle also variable boundaries.&lt;/p&gt;

&lt;p&gt;The approach suggested by &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=svilen.mihaylov&quot; class=&quot;user-hover&quot; rel=&quot;svilen.mihaylov&quot;&gt;svilen.mihaylov&lt;/a&gt;&#160;is to combine the boundaries of intervals via min/max expressions. For instance (f1 &amp;lt; C) AND (f1 &amp;lt; V) is represented as (f1 &amp;lt; min(C, V)). If both C and V turn out to be constant, then constant folding will fold this into the smaller of the two. If at least on is a variable, then the conjunction is rewritten as as MIN expression, and is propagated further through the optimizer.&lt;/p&gt;

&lt;p&gt;A constant folding phase just before execution could fold the min/max boundary expressions into constants.&lt;/p&gt;</description>
