            <title>[SERVER-36631] Have the storage engine interface expose a reduced cache footprint read API</title>
                <link>https://jira.mongodb.org/browse/SERVER-36631</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;WT is exposing a cursor configuration such that an application can communicate it&apos;s intending to read the data only once. Given that knowledge, WT will change its caching behavior of data paged in via that cursor. The expected use-case is for this behavior is when MongoDB knows a client is performing a table scan for initial sync. It may also be useful for oplog reads when the reader is behind and has to start reading a large amount of data.&lt;/p&gt;

&lt;p&gt;It&apos;s not expected that the storage glue layer will have enough information to know when opening a cursor whether it should opt-in to this behavior. This ticket is to expose a public API in the storage layer to allow higher levels declare their &quot;read once&quot; cases.&lt;/p&gt;</description>
