            <title>[SERVER-73641] Timeseries filtering can miss extended-range events when sharded</title>
                <link>https://jira.mongodb.org/browse/SERVER-73641</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-66469&quot; title=&quot;Filtering timeseries with date-field does not include results from before 1970&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-66469&quot;&gt;&lt;del&gt;SERVER-66469&lt;/del&gt;&lt;/a&gt; we fixed timeseries filtering of extended-range data by disabling some predicate pushdown optimizations for collections that have the &quot;requires extended range support&quot; in-memory flag set.&lt;/p&gt;

&lt;p&gt;However, this flag is per-process, so any time one node plans a query to be executed on another, we need to know the value of the flag where the query will execute.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-66469&quot; title=&quot;Filtering timeseries with date-field does not include results from before 1970&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-66469&quot;&gt;&lt;del&gt;SERVER-66469&lt;/del&gt;&lt;/a&gt; attempts to fix this by checking the flag during view resolution, which in a sharded cluster happens on the primary shard.  So if the collection contains extended-range data, but none of it is on the primary shard, mongos will push down more predicates than it should, and the query can miss events outside the 32-bit range.&lt;/p&gt;

&lt;p&gt;We need some mechanism for mongos to know whether extended-range events exist anywhere in the collection.&lt;/p&gt;</description>
