            <title>[SERVER-54819] Consolidate null and missing time-series metadata, or always distinguish</title>
                <link>https://jira.mongodb.org/browse/SERVER-54819</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;An ambiguity arose while implementing &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-53484&quot; title=&quot;Allow rewrite to push meta predicates past $unpackBucket&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-53484&quot;&gt;&lt;del&gt;SERVER-53484&lt;/del&gt;&lt;/a&gt;. It seems that today we are not consistent with treating null as null or missing as null within a time-series collection&apos;s metadata fields. &lt;/p&gt;

&lt;p&gt;This ticket tracks the work to ensure we have consistent behavior and that our rewrite optimizations are correct in the face of nullish metadata being unpacked in $_internalUnpackBucket.&lt;/p&gt;</description>
