            <title>[SERVER-40380] Test that inserting with a unique index and a prepared transaction causes prepare conflicts</title>
                <link>https://jira.mongodb.org/browse/SERVER-40380</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Test that the following scenario will hit prepare conflicts:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Create a collection and add a unique index on the &apos;a&apos; field&lt;/li&gt;
	&lt;li&gt;Start a transaction&lt;/li&gt;
	&lt;li&gt;Insert {&lt;tt&gt;_id: 1, a: 1&lt;/tt&gt;}&lt;/li&gt;
	&lt;li&gt;Update that unsets &apos;a&apos; for {&lt;tt&gt;_id: 1&lt;/tt&gt;}&lt;/li&gt;
	&lt;li&gt;Prepare the transaction&lt;/li&gt;
	&lt;li&gt;Outside of a transaction try to insert {&lt;tt&gt;_id: 2, a: 1&lt;/tt&gt;}&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;If this scenario did not encounter a prepare conflict, it would cause issues when recover prepared transactions at the end of initial sync. The initial insert in the transaction would fail with a duplicate key error and its update would also fail. &lt;/p&gt;</description>
