            <title>[SERVER-26913] Make move/merge/split chunk operations do partial chunk metadata reloads</title>
                <link>https://jira.mongodb.org/browse/SERVER-26913</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;move/merge/split operations use ShardingState::refreshMetadataNow, reloading the entire chunk metadata ~2 times per operation. I suspect this is very costly for collections with large numbers of chunks.&lt;/p&gt;

&lt;p&gt;ShardingState::refreshMetadataNow and ShardingState::onStaleShardVersion are the only two exposed means of refreshing the chunk metadata. Only the latter attempts to do incremental load.&lt;/p&gt;</description>
