            <title>[SERVER-20445] Add support for majority read concern level to Aggregation $out</title>
                <link>https://jira.mongodb.org/browse/SERVER-20445</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;For &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-20214&quot; title=&quot;Stop supporting majority read concern level with MapReduce and Aggregation $out&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-20214&quot;&gt;&lt;del&gt;SERVER-20214&lt;/del&gt;&lt;/a&gt; we are removing support for majority read concern level in these operations because we cannot write in that mode. This ticket is to reenable support.&lt;/p&gt;

&lt;p&gt;The current plan is to emulate majority read concern level by waiting for w:majority in the portions of those operations that write (aggregations including $out and all map reduces) and keep the read concern level for the portions that don&apos;t (aggregations not including $out including all work from the shard phase). It is unclear right now which category inline map reduce falls under. Part of this work is to ensure that this approach is valid. &lt;/p&gt;</description>

I&apos;ve uploaded my work-in-progress here as  &lt;span class=&quot;nobr&quot;&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/attachment/195479/195479_SERVER-20445.patch&quot; title=&quot;SERVER-20445.patch attached to SERVER-20445&quot;&gt;SERVER-20445.patch&lt;sup&gt;&lt;img class=&quot;rendericon&quot; src=&quot;https://jira.mongodb.org/images/icons/link_attachment_7.gif&quot; height=&quot;7&quot; width=&quot;7&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/sup&gt;&lt;/a&gt;&lt;/span&gt;, based on commit 0bb846536e3dda6905bd211db4e4a137705eeb51.&lt;/p&gt;

&lt;p&gt;Simply removing the prohibition on readConcern level &quot;majority&quot; for modes &quot;insertDocuments&quot; and &quot;replaceDocuments&quot; worked, but I faced a problem when it came to actually performing the inserts/updates. The reading portion of the aggregation will read from the majority snapshot, but now the writes will as well. Take a look at the new test I&apos;ve written:&lt;/p&gt;

&lt;p&gt;The assertion on line 77 won&apos;t hold true because updates won&apos;t see the uncommitted data at all. What we really want is for the write portion of $out to &lt;b&gt;not&lt;/b&gt; use the majority snapshot (that is, it should effectively be operating at readConcern level &quot;local&quot;).&lt;/p&gt;</comment>

This work is now in-scope again, but only for modes &quot;insertDocuments&quot; and &quot;replaceDocuments&quot;. We won&apos;t support readConcern level &quot;majority&quot; for &quot;replaceCollection&quot; and will document that appropriately.&lt;/p&gt;</comment>

&lt;p/&gt;
&lt;p&gt;In this trace, it looks like the $out has failed and is trying to drop the temp collection. While doing so, it looks like the index catalog thinks it&apos;s corrupt. My best guess is that somehow a read of the catalog tables cannot find the _id index created by the $out stage because it has not yet been majority committed, but I can&apos;t quite tell what&apos;s going on here. At this point in the test, we have manually set a stable timestamp as the majority commit point, then run the $out without moving the commit point forward, so all changes made by $out will not be part of the stable checkpoint used by majority read concern. I&apos;m not familiar enough with the storage code to know whether/how that will affect catalog operations like this.&lt;/p&gt;</comment>

&lt;p&gt;There are actually multiple backtraces that pop up when you run the read_majority_out.js file. However, there are too many to post, and it&apos;s unclear how useful all of them are. The one above is just the very first backtrace to pop up.&#160;&lt;/p&gt;</comment>

&lt;p&gt;I have attached the relevant patch here:&lt;/p&gt;
