            <title>[JAVA-1558] Bulk API inserts with UNACKNOWLEDGED write concern are translated into individual inserts</title>
                <link>https://jira.mongodb.org/browse/JAVA-1558</link>
                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;When running a bulk insert using the bulk API and an UNACKNOWLEDGED write concern the driver translates this into individual inserts, as opposed to an insert of the list.&lt;/p&gt;

&lt;p&gt;Given the API user has indicated a bulk operation which is unacknowledged, it appears a single insert with all insert operations would be more appropriate. If the user wanted separate inserts, this option is available via the insert API.&lt;/p&gt;

&lt;p&gt;For workloads where the number of inserts is high, the difference in performance is considerable&lt;/p&gt;</description>

We do not plan to change the implementation for when the driver is connected to a server older than MongoDB 3.6.&lt;/p&gt;</comment>
