            <title>[SERVER-65481] Add efficient bulk builder for column indexes</title>
                <link>https://jira.mongodb.org/browse/SERVER-65481</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When bulk building column indexes we can take advantage of the fact that a collection scan produces results in RID order. (We should confirm this with the storage exec team)&lt;/p&gt;

&lt;p&gt;As we walk the collection, we maintain a table from (path -&amp;gt; &lt;span class=&quot;error&quot;&gt;&amp;#91;list of cells ordered by RID&amp;#93;&lt;/span&gt;). For each document we take out of the collection, we produce all of the cells for it, and append them to the corresponding list.&lt;/p&gt;

&lt;p&gt;At the end, we sort by the path (the key of our table) and then insert each list into the index. This avoids doing a blocking sort over the entire set of keys.&lt;/p&gt;</description>
