                            <comment id="5091254" author="charlie.swanson" created="Wed, 4 Jan 2023 21:27:25 +0000"  >&lt;p&gt;I&apos;m using the poc-timeseries-deletes branch to track the work. Starting with multi-deletes. Here&apos;s the diff view, I think I have a decent start: &lt;a href=&quot;https://github.com/10gen/mongo/compare/charlie.swanson/poc-timeseries-deletes?expand=1&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/10gen/mongo/compare/charlie.swanson/poc-timeseries-deletes?expand=1&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Going to look into the following still:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;More testing - look for or add collation tests&lt;/li&gt;
	&lt;li&gt;Refactoring - this approach adds a bad API to ParsedDelete to reset the CanonicalQuery. It&apos;d be better if we could figure out the correct CanonicalQuery right from the start.&lt;/li&gt;
	&lt;li&gt;Properly tracking stats like nDeleted&lt;/li&gt;
	&lt;li&gt;explain?&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;I think I need to wait on &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-72109&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-72109&lt;/a&gt; before I can work on and test some of the retry logic for WriteConflicts. That should be pretty interesting to do too.&lt;/p&gt;</comment>
