            <title>[SERVER-26684] Chunk diffing code roundtrips between ChunkType and BSON during reload</title>
                <link>https://jira.mongodb.org/browse/SERVER-26684</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The chunk diffing &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8844e330821b8b95b2aa01c6ac8a3fbe2fcd5a81/src/mongo/s/chunk_diff.cpp#L123&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;code&lt;/a&gt; serializes a &lt;tt&gt;ChunkType&lt;/tt&gt; object to BSON and then deserializes it just so it can extract the chunk version. This is unnecessary and inefficient since the chunk version is already present in the chunk object.&lt;/p&gt;</description>
