                <project id="14289" key="GODRIVER">Go Driver</project>
                    <description>&lt;h4&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;Summary&lt;/h4&gt;

&lt;p&gt;MongoDB server version and topology: 4.4 / master+ a slave node replica set&lt;/p&gt;

&lt;p&gt;driver version: master&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;%C2%A0&quot;&gt;&lt;/a&gt;&#160;&lt;/h4&gt;
&lt;h4&gt;&lt;a name=&quot;HowtoReproduce&quot;&gt;&lt;/a&gt;How to Reproduce&lt;/h4&gt;
&lt;ol&gt;
	&lt;li&gt;&#160;Down the master node.Now only a slave node is on lived.&lt;/li&gt;
	&lt;li&gt;use uri mongodb://&lt;span class=&quot;error&quot;&gt;&amp;#91;username&amp;#93;&lt;/span&gt;:&lt;span class=&quot;error&quot;&gt;&amp;#91;password&amp;#93;&lt;/span&gt;@master_ip,slave_ip/db_name&lt;/li&gt;
	&lt;li&gt;Set the client option readPreference to primaryPreferred&lt;/li&gt;
	&lt;li&gt;Then NewClient and ListCollections.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;The code like:&lt;/p&gt;
&lt;p/&gt;

Unfortunately the cross-drivers ticket has been closed as &#8220;won&#8217;t do&#8221;. We recognize that it might be helpful to respect read preference for enumerative, administrative helpers like &lt;tt&gt;listCollections&lt;/tt&gt;, but it seems like the underlying issue here is the lack of availability of your replica set&#8217;s primary. Is there anything we can do to help with your availability issues? Are you seeing consistent, long-running shutdowns of your primary node?&lt;/p&gt;</comment>

Those are some fair points, and I&apos;ve re-opened a cross-drivers ticket to consider honoring the user&apos;s &lt;tt&gt;readPreference&lt;/tt&gt; for enumerative, administrative commands such as &lt;tt&gt;listCollections&lt;/tt&gt;. I&apos;ve linked &lt;a href=&quot;https://jira.mongodb.org/browse/DRIVERS-1186&quot; title=&quot;Allow db/collection/index enumeration to respect read preference&quot; class=&quot;issue-link&quot; data-issue-key=&quot;DRIVERS-1186&quot;&gt;&lt;del&gt;DRIVERS-1186&lt;/del&gt;&lt;/a&gt; to this ticket.&lt;/p&gt;</comment>
                            <comment id="4388418" author="JIRAUSER1253736" created="Thu, 3 Mar 2022 04:55:17 +0000"  >&lt;p&gt;Yes,because mongodump was written by golang, so I call the `dump` method.&lt;/p&gt;

&lt;p&gt;Recently, I wanted to implement a way to have the backup function work when the host is down.When use uri like this `&#160;uri mongodb://&lt;span class=&quot;error&quot;&gt;&amp;#91;username&amp;#93;&lt;/span&gt;:&lt;span class=&quot;error&quot;&gt;&amp;#91;password&amp;#93;&lt;/span&gt;@master_ip,slave_ip/db_name`, It&apos;s not work ok.&lt;/p&gt;

&lt;p&gt;Although it is possible to connect directly to the backup machine, I have to write very ugly logic to get the address of the backup machine.&lt;/p&gt;

&lt;p&gt;To be honest, I am puzzled by this design. What is the advantage of connecting directly to the slave and leaving the choice of setting read mode to the client?&lt;img class=&quot;emoticon&quot; src=&quot;https://jira.mongodb.org/images/icons/emoticons/sad.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;

&lt;p&gt;It will make the user wonder why it still times out even though I set PrimaryPreferred.&lt;img class=&quot;emoticon&quot; src=&quot;https://jira.mongodb.org/images/icons/emoticons/sad.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;

&lt;p&gt;Hope you will discuss this &lt;a href=&quot;https://github.com/mongodb/specifications/blob/master/source/enumerate-collections.rst#replica-sets&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;draft &lt;/a&gt;again QAQ.&lt;/p&gt;

&lt;p&gt;Best wishes,&lt;/p&gt;

&lt;p&gt;Liu&lt;/p&gt;</comment>
                            <comment id="4387915" author="benji.rewis" created="Wed, 2 Mar 2022 22:01:30 +0000"  >&lt;blockquote&gt;&lt;p&gt;Sometimes we do need this feature when the primary node is down.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;Are &lt;a href=&quot;https://docs.mongodb.com/manual/core/retryable-reads/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;retryable reads&lt;/a&gt; useful in this case? It seems like the operation could retry and potentially succeed once the primary is back up. Or, in your case, is the primary expected to be down for an extended period of time?&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;this feature directly affects mongodump.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;To clarify, are you using the&#160;&lt;tt&gt;mongodump&lt;/tt&gt;&#160;tool, and an internal call to the Go driver&apos;s &lt;tt&gt;ListCollections&lt;/tt&gt; is failing?&lt;/p&gt;</comment>
                            <comment id="4385518" author="JIRAUSER1253736" created="Wed, 2 Mar 2022 07:06:48 +0000"  >&lt;p&gt;`primaryPreferred` might be a better choise.&lt;/p&gt;</comment>
                            <comment id="4385512" author="JIRAUSER1253736" created="Wed, 2 Mar 2022 06:53:58 +0000"  >&lt;p&gt;You are right, but would it be better to leave this parameter to the client, or set it to primaryPreferred. Sometimes we do need to use this feature when the primary node is down. And this feature directly affects mongodump.&lt;img class=&quot;emoticon&quot; src=&quot;https://jira.mongodb.org/images/icons/emoticons/biggrin.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;</comment>
                            <comment id="4383762" author="benji.rewis" created="Tue, 1 Mar 2022 16:45:55 +0000"  >&lt;p&gt;Hello again, &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=mrliuxiansen8023%40gmail.com&quot; class=&quot;user-hover&quot; rel=&quot;mrliuxiansen8023@gmail.com&quot;&gt;mrliuxiansen8023@gmail.com&lt;/a&gt;! Thanks for your bug report. As you discovered in the &lt;tt&gt;ListCollections&lt;/tt&gt; code, we do &lt;a href=&quot;https://github.com/mongodb/mongo-go-driver/blob/master/mongo/database.go#L371&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;force a read preference&lt;/a&gt; of primary for the command. While the &lt;tt&gt;listCollections&lt;/tt&gt; command can be run on primary or secondary nodes (see the server manual &lt;a href=&quot;https://docs.mongodb.com/manual/reference/command/listCollections/#replica-set-member-state-restriction&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;), our cross-drivers specifications &lt;a href=&quot;https://github.com/mongodb/specifications/blob/master/source/enumerate-collections.rst#replica-sets&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;say&lt;/a&gt;:&lt;/p&gt;

&lt;blockquote&gt;&lt;p&gt;Drivers MUST run listCollections on the primary node when in a replica set topology, unless directly connected to a secondary node in Single topology.&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;We enforce the primary read preference as a call to &lt;tt&gt;listCollections&lt;/tt&gt; on a secondary node may return inaccurate (not up-to-date) information. For example, if you created a collection (a write operation that will always be routed to the primary) and immediately ran &lt;tt&gt;listCollections&lt;/tt&gt; on the secondary, that new collection may not be present in the returned list.&lt;/p&gt;</comment>
