            <title>[SERVER-50598] Not allow tenant migration donor to write &quot;commitIndexBuild&quot; oplog entries after migration enters blocking state</title>
                <link>https://jira.mongodb.org/browse/SERVER-50598</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently, the tenant migration donor is allowed to write both &quot;commitIndexBuild&quot; and &quot;abortIndexBuild&quot; oplog entries with oplog timestamp greater than the blockTimestamp, since if the donor doesn&apos;t write either a commit or abort oplog entry, some resources will not be released on the donor node and this can lead to deadlocks.&lt;/p&gt;

&lt;p&gt;Since the recipient doesn&apos;t clone oplog entries beyond the blockTimestamp, it is safe to allow the donor to write&#160;&quot;abortIndexBuild&quot; oplog entries after the blockTimestamp. With that, it is also safe to reject&#160;&quot;commitIndexBuild&quot; oplog entries after the blockTimestamp since the donor would be able to abort and clean up an index build that fails due to migration conflict.&#160;&lt;/p&gt;</description>
