            <title>[SERVER-82707] Improve CatalogCache eviction policy</title>
                <link>https://jira.mongodb.org/browse/SERVER-82707</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently the sharding catalog cache eviction policy is LRU with &lt;a href=&quot;https://github.com/mongodb/mongo/blob/36ae3cfc5d338423cbcc34572a30cad503be35e2/src/mongo/s/catalog_cache.cpp#L101-L103&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;a hardcoded capacity of 10k entries&lt;/a&gt;. There are some improvements we could consider:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Making the capacity configurable.&lt;/li&gt;
	&lt;li&gt;Considering the size of the cached entry, which may vary wildly depending on each collection routing table size.&lt;/li&gt;
	&lt;li&gt;Being more aggressive in evicting long-unused entries.&lt;/li&gt;
&lt;/ul&gt;
