            <title>[SERVER-17126] Improve rocks engine</title>
                <link>https://jira.mongodb.org/browse/SERVER-17126</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Over last couple of weeks wiredtiger landed some improvements. We need to port those improvements to rocksdb, too. Namely:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;checked_cast&amp;lt;&amp;gt; instead of dynamic_cast&amp;lt;&amp;gt; to speed up release build&lt;/li&gt;
	&lt;li&gt;optimization to IndexCursor::pointsToSamePlaceAs()&lt;/li&gt;
	&lt;li&gt;don&apos;t assume dupKeyError on Index::insert() conflict&lt;/li&gt;
	&lt;li&gt;trigger massert() when RocksRecordStore::dataFor() can&apos;t find the RecordId. Currently we return nullptr which just causes SIGSEGV.&lt;/li&gt;
&lt;/ul&gt;
