            <title>[SERVER-8371] Include sorting information into profile</title>
                <link>https://jira.mongodb.org/browse/SERVER-8371</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Hi Mongo,&lt;/p&gt;

&lt;p&gt;I am currently writing integration tests for my application. So I wanted to make sure that all queries are appropriately using indexes. My intention was to request all unique queries from system.profile and to run explain plans and see whether indexes used. &lt;/p&gt;

&lt;p&gt;This could not be completed, as there is no sorting information in the system.profile however sorting affects indexes. My request to include sorting into system.profile&lt;/p&gt;

&lt;p&gt;Thanks&lt;/p&gt;</description>

                            <comment id="252951" author="drapeko" created="Tue, 29 Jan 2013 17:03:25 +0000"  >&lt;p&gt;No! Imagine, you have a users collection. And you have created an index on this collection: user(name, createdAt). Now I would like to find out some users sorted by time. In system.profile the second part of the query (sorting/pagination) won&apos;t be saved, however it&apos;s very important to understand what sorting operation were used, as it affects the performance and index selection. &lt;/p&gt;

&lt;p&gt;So my intention was to create a script that will go through all statements in system.profile and execute explain plans and see whether indexes are used or not. If not, I can automatically catch all new/not reliable queries while executing integration tests.&lt;/p&gt;</comment>

&lt;/table&gt;
&lt;/div&gt;

&lt;p&gt;Is this what you mean?&lt;/p&gt;</comment>
