            <title>[SERVER-64128] Investigate behavior when query against unsharded collection runs concurrently with shardCollection and moveChunk</title>
                <link>https://jira.mongodb.org/browse/SERVER-64128</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Suppose a query is running against an unsharded collection and a concurrent &apos;shardCollection&apos; shards the collection and a &apos;moveChunk&apos; moves a chunk away from the primary shard. When the query yields and reacquires a snapshot of the collection, it&apos;s not clear whether there&apos;s anything that will protect the query from &apos;observing&apos; that the collection has not only become sharded, but also some of the data has moved away from the primary shard. This ticket tracks the work to write a test that demonstrates the current behavior of the above scenario.&lt;/p&gt;</description>
