            <title>[SERVER-6829] splitting with few chunks will never succeed if many duplicates</title>
                <link>https://jira.mongodb.org/browse/SERVER-6829</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;If for some reason the data being inserted has a few duplicate shard keys (no so many as to cause problems) we will never split the initial chunk.&lt;/p&gt;

&lt;p&gt;For example, if we&apos;re inserting documents of size 300k and insert two documents in a row with the same shard key each time, we&apos;ll never split b/c for a split with only one chunk, the maxChunkSize is forced to 1024 bytes, and 1/2 of that is 500k.  &lt;/p&gt;

&lt;p&gt;Would be better to specify a different parameter as a target chunk size and split between targetChunkSize and maxChunkSize wherever possible.  Mongod could also be smarter here since it knows the actual size of the initial chunk.&lt;/p&gt;</description>
