            <title>[SERVER-29531] Handle Rollbacks in SessionTransactionTable</title>
                <link>https://jira.mongodb.org/browse/SERVER-29531</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There will be special logic required for rollback since updates to the systems.transaction won&apos;t have any oplog entries and won&apos;t be rolled back to the right state.&lt;/p&gt;

&lt;p&gt;This can be resolved by:&lt;br/&gt;
Approach1: copying the full table from the sync source as part of the rollback process. This should be done before the minValid opTime is determined and set. Cons: Can be expensive since there can be many documents that needs to be copied over (one doc per statement)&lt;br/&gt;
Approach2: Remove the corresponding transaction statement entries from transaction table (both in-memory cache and storage) by inspecting the (sessionId, txnNum and stmtId) of the oplog entry. Cons: Cannot revert state back to older transactions in a session.&lt;/p&gt;</description>
