            <title>[SERVER-40183] Create kill_sessions version of multi_statement_transaction_simple.js concurrency workload</title>
                <link>https://jira.mongodb.org/browse/SERVER-40183</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Similar to &lt;tt&gt;multi_statement_transaction_kill_sessions_atomicity_isolation.js&lt;/tt&gt;, a kill sessions version of &lt;tt&gt;multi_statement_transaction_simple.js&lt;/tt&gt; should be created to ensure there is coverage for killing sessions during two phase commit. This is necessary because the only multi shard transaction run by the atomicity isolation workload is a read, which skips two phase commit because of the recently added read only optimizations. &lt;tt&gt;multi_statement_transaction_simple.js&lt;/tt&gt; instead runs a &lt;a href=&quot;https://github.com/mongodb/mongo/blob/564cfd0ede845a9c20280a352c544b36f6b74471/jstests/concurrency/fsm_workloads/multi_statement_transaction_simple.js#L57-L67&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;transaction with two updates on different _id values&lt;/a&gt;, which cannot skip two phase commit if the affected documents are on different shards, which happens randomly depending on the hashed sharding distribution for the chosen values.&lt;/p&gt;

&lt;p&gt;As part of this ticket, other concurrency workloads can be considered for kill sessions versions as well, like &lt;tt&gt;multi_statement_transaction_all_commands.js&lt;/tt&gt; and &lt;tt&gt;random_moveChunk_broadcast_{update,delete}_transaction.js&lt;/tt&gt;.&lt;/p&gt;</description>
