            <title>[SERVER-83492] Remove limit and skip values from SBE plan cache key if possible</title>
                <link>https://jira.mongodb.org/browse/SERVER-83492</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We encode exact limit and skip values as part of cache key in SBE:&lt;br/&gt;
&lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/db/query/canonical_query_encoder.cpp#L1176&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;encodeSBE&lt;/a&gt;&#160;calls&#160;encodeFindCommandRequest] that encodes skip and limit values.&lt;/p&gt;

&lt;p&gt;While&#160;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/db/query/canonical_query_encoder.cpp#L1112&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;encodeClassic&lt;/a&gt;&#160;doesn&apos;t do it.&lt;/p&gt;

&lt;p&gt;This may cause plan cache bloat and excessive multi planning in SBE.&lt;/p&gt;</description>

We have to move them to slots and make this slots input parameters instead.&lt;/p&gt;</comment>
