            <title>[GODRIVER-1707] Inbuilt Support For Getting Keys in a Sub Document.</title>
                <link>https://jira.mongodb.org/browse/GODRIVER-1707</link>
                <project id="14289" key="GODRIVER">Go Driver</project>
                    <description>&lt;p&gt;Hi, We should support an inbuilt capability in the mongo driver to fetch the distinguished keys in a sub-document&lt;br/&gt;
 For Ex:&lt;br/&gt;
&quot;nodes&quot; : &lt;/p&gt;
{
            &quot;master&quot; : \{ ... }
&lt;p&gt;,&lt;br/&gt;
            &quot;worker&quot; : { ... }&lt;br/&gt;
So the functionality should work like. If I provide the path to nodes. It should give me all the keys in a tree structure.&lt;/p&gt;

&lt;p&gt;this will be very handy just to have keys from the driver it self.&lt;/p&gt;</description>

As I mentioned before, we don&apos;t think this is a very common use case and are therefore going to hold off on adding it to the driver right now. I&apos;m going to close this ticket, but we can revisit and potentially open it again if we see this use case come up again from other users.&lt;/p&gt;

Yep! I too did something in my code. But thought to give this as suggestion as people may find it useful if it comes out if the box.&lt;br/&gt;
but np thankyou so much for taking the time and reading the ticket.&lt;/p&gt;</comment>
                            <comment id="3339748" author="divjot.arora" created="Fri, 14 Aug 2020 16:54:16 +0000"  >&lt;p&gt;I don&apos;t think this is something we want to add to the driver&apos;s public API because it&apos;s not a common use case and users will have different requirements. Some may want a list of only top-level keys. Others might want a list of all keys, where nested ones are in the format &quot;topLevelKey.nestedKey&quot;. I&apos;ve written up some code using FindOne to do this that you can migrate to your application:&#160;&lt;a href=&quot;https://gist.github.com/divjotarora/27dfabb358771f526f661a9ec79f9f43&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://gist.github.com/divjotarora/27dfabb358771f526f661a9ec79f9f43&lt;/a&gt;. The one thing I noticed is that our &lt;tt&gt;bson.Raw&lt;/tt&gt; type has a method to get a slice of Elements, which are key/value pairs, and a method to get just&#160; a slice of values, but not one to get a slice of keys, so there&apos;s an extra loop required in the code to get the keys from the elements. If you think it would help reduce complexity a bit, I can file a ticket to add a &lt;tt&gt;bson.Raw.Keys&lt;/tt&gt; method.&lt;/p&gt;

                            <comment id="3339681" author="JIRAUSER1254844" created="Fri, 14 Aug 2020 16:30:34 +0000"  >&lt;p&gt;It depends on how we want to do it. The approach should be optimized.&#160;&lt;/p&gt;




&lt;p&gt;Q.). Do you want to get a list of keys from a specific document in a collection?&lt;br/&gt;
Ans: It can be a document in a collection or sub-document.&lt;br/&gt;
The queried thing should be at the document level not at the whole collection level. It will be implemented with FindOne.&lt;/p&gt;

&lt;p&gt;Q.).&#160;&#160;would it be reasonable to first run&#160;&lt;tt&gt;Collection.Find&lt;/tt&gt;&#160;or&#160;&lt;tt&gt;Collection.FindOne&lt;/tt&gt;&#160;to get the document and then creating a slice of keys in the application/driver&#160;or does your use case require getting a list of keys directly from the server?&lt;br/&gt;
Ans: Yes, this is one approach. But if server internally support to fetching keys efficiently than why not do there.&lt;/p&gt;</comment>
                            <comment id="3339645" author="divjot.arora" created="Fri, 14 Aug 2020 16:19:16 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=shantanubansal05%40gmail.com&quot; class=&quot;user-hover&quot; rel=&quot;shantanubansal05@gmail.com&quot;&gt;shantanubansal05@gmail.com&lt;/a&gt;,&lt;/p&gt;

&lt;p&gt;I&apos;d like to get a few more details before I make suggestions. Do you want to get a list of keys from a specific document in a collection? Or a list of keys of documents? If it&apos;s for a specific document, would it be reasonable to first run &lt;tt&gt;Collection.Find&lt;/tt&gt; or &lt;tt&gt;Collection.FindOne&lt;/tt&gt; to get the document and then creating a slice of keys in the application/driver or does your use case require getting a list of keys directly from the server?&lt;/p&gt;

&lt;p&gt;What I mean is we should be able to fetch the keys in the document or sub-document.&#160;&lt;/p&gt;

&lt;p&gt;I didn&apos;t quite follow the request in the description. Can you provide a complete minimal example of a stored document and what information you&apos;d like to get from it? If possible, it&apos;d also be helpful to know which of the driver&apos;s currently exported methods you&apos;d like to use to get this information.&lt;/p&gt;
