            <title>[SERVER-79924] Use an accurate &apos;isCount&apos; flag to encode a CanonicalQuery for SBE plan cache</title>
                <link>https://jira.mongodb.org/browse/SERVER-79924</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently the SBE plan cache key encoding uses &lt;a href=&quot;https://github.com/10gen/mongo/blob/eeac78cd8de74ca1cffb18eb4b798b8392df6192/src/mongo/db/query/canonical_query_encoder.cpp#L1151&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;isCountLike&lt;/a&gt; which is inaccurate. Queries with &lt;a href=&quot;https://github.com/10gen/mongo/blob/eeac78cd8de74ca1cffb18eb4b798b8392df6192/src/mongo/db/query/canonical_query.h#L377-L384&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;_isCountLike&lt;/a&gt; being true don&apos;t necessary use COUNT_SCAN plan. This could cause a IXSCAN plan and a COUNT_SCAN plan share a same SBE plan cache key.&lt;/p&gt;</description>
