            <title>[SERVER-74043] Reading From Primary and secondary giving different sequence</title>
                <link>https://jira.mongodb.org/browse/SERVER-74043</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;h3&gt;&lt;a name=&quot;ProblemStatement%2FRationale&quot;&gt;&lt;/a&gt;&lt;b&gt;Problem Statement/Rationale&lt;/b&gt;&lt;/h3&gt;

&lt;p&gt;&lt;font color=&quot;#505f79&quot;&gt;Sequence of data coming is different while reading from secondary and Primary&lt;/font&gt;&lt;/p&gt;

&lt;p&gt;&lt;b&gt;Please be sure to attach relevant logs &lt;em&gt;with any sensitive data redacted&lt;/em&gt;.&lt;/b&gt;&lt;/p&gt;
&lt;h3&gt;&lt;a name=&quot;StepstoReproduce&quot;&gt;&lt;/a&gt;&lt;b&gt;Steps to Reproduce&lt;/b&gt;&lt;/h3&gt;

&lt;p&gt;mongos&amp;gt; db.products.insertMany( [&lt;br/&gt;
... &#160; &#160; &#160; { _id: 10, item: &quot;1&quot;, qty: 20 },&lt;br/&gt;
... &#160; &#160; &#160; { _id: 11, item: &quot;2&quot;, qty: 20 },&lt;br/&gt;
... &#160; &#160; &#160; { _id: 12, item: &quot;3&quot;, qty: 20 }&lt;br/&gt;
... &#160; &#160;] );&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;reading:&lt;/p&gt;

&lt;p&gt;mongos&amp;gt; db.products.find().readPref(&quot;primary&quot;)&lt;/p&gt;
{ &quot;_id&quot; : 10, &quot;item&quot; : &quot;1&quot;, &quot;qty&quot; : 20 }
{ &quot;_id&quot; : 11, &quot;item&quot; : &quot;2&quot;, &quot;qty&quot; : 20 }
{ &quot;_id&quot; : 12, &quot;item&quot; : &quot;3&quot;, &quot;qty&quot; : 20 }


&lt;p&gt;mongos&amp;gt; db.products.find().readPref(&quot;secondary&quot;)&lt;/p&gt;
{ &quot;_id&quot; : 10, &quot;item&quot; : &quot;1&quot;, &quot;qty&quot; : 20 }
{ &quot;_id&quot; : 12, &quot;item&quot; : &quot;3&quot;, &quot;qty&quot; : 20 }
{ &quot;_id&quot; : 11, &quot;item&quot; : &quot;2&quot;, &quot;qty&quot; : 20 }
&lt;h3&gt;&lt;a name=&quot;ExpectedResults&quot;&gt;&lt;/a&gt;&lt;b&gt;Expected Results&lt;/b&gt;&lt;/h3&gt;

&lt;p&gt;&lt;font color=&quot;#505f79&quot;&gt;reading from secondary should also come with same order without sorting that field.&lt;/font&gt;&lt;/p&gt;

&lt;p&gt;&lt;font color=&quot;#505f79&quot;&gt;{ &quot;_id&quot; : 10, &quot;item&quot; : &quot;1&quot;, &quot;qty&quot; : 20 }
{ &quot;_id&quot; : 11, &quot;item&quot; : &quot;2&quot;, &quot;qty&quot; : 20 }
{ &quot;_id&quot; : 12, &quot;item&quot; : &quot;3&quot;, &quot;qty&quot; : 20 }&lt;/font&gt;&lt;/p&gt;
&lt;h3&gt;&lt;a name=&quot;ActualResults&quot;&gt;&lt;/a&gt;&lt;b&gt;Actual Results&lt;/b&gt;&lt;/h3&gt;

{ &quot;_id&quot; : 10, &quot;item&quot; : &quot;1&quot;, &quot;qty&quot; : 20 }
{ &quot;_id&quot; : 11, &quot;item&quot; : &quot;2&quot;, &quot;qty&quot; : 20 }
{ &quot;_id&quot; : 12, &quot;item&quot; : &quot;3&quot;, &quot;qty&quot; : 20 }
&lt;h3&gt;&lt;a name=&quot;AdditionalNotes&quot;&gt;&lt;/a&gt;&lt;b&gt;Additional Notes&lt;/b&gt;&lt;/h3&gt;

&lt;p&gt;&lt;font color=&quot;#505f79&quot;&gt;Any additional information that may be useful to include.&lt;/font&gt;&lt;/p&gt;</description>
