            <title>[SERVER-65804] Enhance BSONColumn to allow checking contained element types without decompressing</title>
                <link>https://jira.mongodb.org/browse/SERVER-65804</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Occasionally we just need to know information about the types of elements in a compressed BSONColumn (e.g. does the column contain an array?). We should be able to provide this information in some cases without having to decompress and iterate over the elements of the column. This should provide a clear performance benefit.&lt;/p&gt;</description>
