            <title>[SERVER-78271] Add writeEndOfTransaction internal command</title>
                <link>https://jira.mongodb.org/browse/SERVER-78271</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This command will be used by transaction coordinator to tell shards to write endOfTransaction no-op oplog entry.&lt;/p&gt;

&lt;p&gt;It should accept:&lt;br/&gt;
1. Transaction information (lsid, txnNumber, retryCounter)&lt;br/&gt;
2. List of affected namespaces with shard versions.&lt;/p&gt;


&lt;p&gt;It should:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Check for each affected namespace that this shard has at least one chunk for this namespace.&lt;/li&gt;
	&lt;li&gt;Return stale error if it is not true&lt;/li&gt;
	&lt;li&gt;Return ok and write end-of-transaction oplog entry if true.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;Optionally, we can do checks independently for each namespaces, so if shard has only some namespaces, it can return to the caller the list of &quot;accepted&quot; namespaces and &quot;rejected&quot; namespaces. This will introduce some complexity, but may potentially lower the number of retries in volatile environment&lt;/p&gt;</description>
