                <link>https://jira.mongodb.org/browse/DOCS-14048</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h2&gt;&lt;a name=&quot;Description&quot;&gt;&lt;/a&gt;Description&lt;/h2&gt;
&lt;p&gt;Investigate mapReduce refactoring&lt;/p&gt;

&lt;h2&gt;&lt;a name=&quot;Scopeofchanges&quot;&gt;&lt;/a&gt;Scope of changes&lt;/h2&gt;
&lt;p&gt;Per Jeff:&lt;/p&gt;

&lt;p&gt;Key places where we&apos;re not calling out map-reduce being&lt;br/&gt;
deprecated. See&lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Let&apos;s remove map-reduce content from&lt;br/&gt;
&lt;a href=&quot;https://docs.mongodb.com/manual/tutorial/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/tutorial/&lt;/a&gt;. Even though this page is orphaned,&lt;br/&gt;
people still find it.&lt;br/&gt;
Jason comment: Done.&lt;/li&gt;
&lt;/ul&gt;



&lt;p&gt;-&lt;br/&gt;
&lt;a href=&quot;https://docs-mongodbcom-staging.corp.mongodb.com/jason.price/DOCSP-7670-Deprecate-mapReduce-command/core/aggregation-pipeline.html#aggregation-pipeline-vs-map-reduce&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs-mongodbcom-staging.corp.mongodb.com/jason.price/DOCSP-7670-Deprecate-mapReduce-command/core/aggregation-pipeline.html#aggregation-pipeline-vs-map-reduce&lt;/a&gt;&lt;br/&gt;
in this section we should probably mention MR is deprecated.&lt;br/&gt;
Jason comment: Done.&lt;/p&gt;

&lt;p&gt;-&lt;br/&gt;
&lt;a href=&quot;https://docs-mongodbcom-staging.corp.mongodb.com/jason.price/DOCSP-7670-Deprecate-mapReduce-command/core/map-reduce.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs-mongodbcom-staging.corp.mongodb.com/jason.price/DOCSP-7670-Deprecate-mapReduce-command/core/map-reduce.html&lt;/a&gt;&lt;br/&gt;
(and sub-pages where appropriate).&lt;br/&gt;
Jason comment: Done.&lt;/p&gt;

&lt;p&gt;-&lt;br/&gt;
&lt;a href=&quot;https://docs-mongodbcom-staging.corp.mongodb.com/jason.price/DOCSP-7670-Deprecate-mapReduce-command/aggregation.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs-mongodbcom-staging.corp.mongodb.com/jason.price/DOCSP-7670-Deprecate-mapReduce-command/aggregation.html&lt;/a&gt;&lt;br/&gt;
This page still has a large section for map-reduce. Do we really want that&lt;br/&gt;
section on the main aggregation page for something that&apos;s now deprecated? &lt;/p&gt;

&lt;p&gt;That same page also has a sentence in the opening blurb which reads &quot;MongoDB&lt;br/&gt;
provides three ways to perform aggregation: the aggregation pipeline, the&lt;br/&gt;
map-reduce function, and single purpose aggregation methods.&quot; We probably don&apos;t&lt;br/&gt;
want to mention the deprecated map reduce in the opening blurb for aggregation.&lt;br/&gt;
Jason comment: Removed mention of map-reduce and rewrote as needed.&lt;/p&gt;


&lt;p&gt;I suggest reviewing the content on the main Aggregation page and see if there&lt;br/&gt;
are any other places where it makes sense to adjust the copy to reflect&lt;br/&gt;
map-reduce being deprecated.&lt;/p&gt;

&lt;p&gt;There are likely other places which need to be addressed. I just did a quick&lt;br/&gt;
ctrl+f through the docs for &quot;mapreduce&quot; and &quot;map-reduce&quot; to find some of those&lt;br/&gt;
references.&lt;br/&gt;
Jason comment: Will go through the rest of the pages and adjust content as needed.&lt;br/&gt;
Per Jeff, will mark mapReduce command references as deprecated.&lt;/p&gt;

&lt;p&gt;Per Jeff, we will probably do a phase 2 refactor of pages like:&lt;br/&gt;
&lt;a href=&quot;https://docs.mongodb.com/manual/reference/aggregation-commands-comparison/index.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/reference/aggregation-commands-comparison/index.html&lt;/a&gt;&lt;/p&gt;

&lt;h2&gt;&lt;a name=&quot;ImpacttoOtherDocs&quot;&gt;&lt;/a&gt;Impact to Other Docs&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;MVP%28WorkandDate%29&quot;&gt;&lt;/a&gt;MVP (Work and Date)&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;Resources%28ScopeorDesignDocs%2CInvision%2Cetc.%29&quot;&gt;&lt;/a&gt;Resources (Scope or Design Docs, Invision, etc.)&lt;/h2&gt;
