            <title>[SERVER-65299] Not reset RetryableWriteTransactionParticipantCatalog upon starting an internal transaction for non-retryable write</title>
                <link>https://jira.mongodb.org/browse/SERVER-65299</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://github.com/mongodb/mongo/blob/c96f8dacc4c71b4774c932a07be4fac71b6db628/src/mongo/db/transaction_participant.cpp#L855&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Resetting&lt;/a&gt; the&#160;RetryableWriteTransactionParticipantCatalog upon&#160;starting an internal transaction for a non-retryable write leads to an invariant failure in the following case.&lt;/p&gt;

&lt;p&gt;Consider a sharded collection with two chunks: chunk0 and chunk1, which reside on shard0 and shard1, respectively.&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;The client starts a retryableWrite=false session S and performs a write against chunk0 in a transaction T0 with txnNumber0.&lt;/li&gt;
	&lt;li&gt;chunk0 is moved from shard0 to shard1. During the migration, shard1 writes a dead-end sentinel noop oplog entry for T0.&lt;/li&gt;
	&lt;li&gt;chunk0 is moved from shard1 back to shard0.&lt;/li&gt;
	&lt;li&gt;The client performs a write against chunk1 in the session S outside a transaction. The write needs to executed using a transaction so the router executes it in an internal transaction for non-retryable write T1. Upon starting T1, shard1 resets/invalidates the&#160;RetryableWriteTransactionParticipantCatalog for S.&lt;/li&gt;
	&lt;li&gt;chunk0 is moved from shard0 to shard1 again. During the migration, shard1 hits this &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c96f8dacc4c71b4774c932a07be4fac71b6db628/src/mongo/db/transaction_participant.cpp#L3040-L3041&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;invariant&lt;/a&gt;&#160;when &lt;a href=&quot;https://github.com/mongodb/mongo/blob/31476676d66797484049dd1315983bd99d0c5c50/src/mongo/db/s/session_catalog_migration_destination.cpp#L260-L263&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;processing&lt;/a&gt;&#160;the dead-end sentinel noop oplog entry for T0. Note that beginOrContinue() does not fail on shard1 with &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c96f8dacc4c71b4774c932a07be4fac71b6db628/src/mongo/db/transaction_participant.cpp#L732-L734&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;InCompleteTransactionHistory&lt;/a&gt;&#160;because from the perspective of shard1, txnNumber0 has always corresponded to a retryable write because of the dead-end sentinel oplog entry it wrote in step 2.&lt;/li&gt;
&lt;/ol&gt;
