            <title>[SERVER-81097] Allow the `restore` role to do all DDL on time-series buckets.</title>
                <link>https://jira.mongodb.org/browse/SERVER-81097</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The server forbids some DDL operations, like shardCollection and drop, on time-series buckets collections. For most applications this is sensible, but it prevents mongosync from sending a `collectionUUID` when doing these operations.&lt;/p&gt;

&lt;p&gt;For now that&apos;s OK because mongosync only does single-threaded DDL; however, as of REP-2924 mongosync will augment preexisting namespaces, which means we&apos;ll potentially have multiple mongosyncs syncing to the same collection.&lt;/p&gt;

&lt;p&gt;Unless we&apos;re going to disavow data integrity for time-series in these situations, then, the server will need to allow mongosync to do full DDL on time-series bucket collections. These operations should all accept `collectionUUID` as well.&lt;/p&gt;

&lt;p&gt;I envision that, as with &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-77003&quot; title=&quot;Allow renames of time-series collection buckets&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-77003&quot;&gt;&lt;del&gt;SERVER-77003&lt;/del&gt;&lt;/a&gt;, the server will only allow this functionality to clients with the `restore` role.&lt;/p&gt;</description>

This doesn&#8217;t block mongosync after all, at least until REP-2924.&lt;/p&gt;</comment>
                            <comment id="5742030" author="JIRAUSER1272372" created="Fri, 29 Sep 2023 20:56:11 +0000"  >&lt;p&gt;Of note: I&#8217;m currently tracking &lt;a href=&quot;https://jira.mongodb.org/browse/REP-2771?focusedCommentId=5740778&amp;amp;page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-5740778&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;a test failure on my time-series branch&lt;/a&gt; (REP-2771) where it appears that the UUID-less `drop` caused corruption on the destination due to a faulty interaction between mongosync&#8217;s initial sync and the change event application (&#8220;oplog rollover resilience&#8221;) that we run concurrently therewith.&lt;/p&gt;

&lt;p&gt;I&#8217;m still digging into it, but this &lt;em&gt;may&lt;/em&gt; impede us after all.&lt;/p&gt;</comment>
                            <comment id="5731919" author="JIRAUSER1272372" created="Tue, 26 Sep 2023 16:20:45 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=gregory.wlodarek%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;gregory.wlodarek@mongodb.com&quot;&gt;gregory.wlodarek@mongodb.com&lt;/a&gt; This doesn&#8217;t block mongosync for the immediate purpose of time-series support.&lt;/p&gt;

&lt;p&gt;Our forthcoming many-to-one feature, though, will suffer from time-series data inconsistencies without this. We&#8217;d ideally like not to have to tell users to avoid many-to-one with time-series collections.&lt;/p&gt;</comment>
