            <title>[SERVER-73465] Updates during column store index build can result in no-op side writes</title>
                <link>https://jira.mongodb.org/browse/SERVER-73465</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When a column store index is limited to a subset of columns (either by a &lt;tt&gt;columnstoreProjection&lt;/tt&gt; or by &lt;tt&gt;&quot;foo.$**&quot;&lt;/tt&gt;-style notation), it is possible for a document replacement update to get forwarded to the index even when it does not modify any of the indexed columns. When this happens during bulk building, it results in a &quot;side write&quot; that has no entries.&lt;/p&gt;

&lt;p&gt;That behavior is semantically correct but trips an invariant when it eventually gets processed. There is no need for these no-op entries, though, and it is a simple to change the index update code so that it does not write them.&lt;/p&gt;</description>
