            <title>[COMPASS-422] mongodb-schema: provide a memory limit parameter</title>
                <link>https://jira.mongodb.org/browse/COMPASS-422</link>
                <project id="13182" key="COMPASS">Compass </project>
                    <description>&lt;p&gt;mongodb-schema should take a memory limit parameter and stop analysing the schema when that limit is reached. &lt;/p&gt;

&lt;p&gt;It could either (a) stop adding values and simply update counts/probabilities, or (b) stop sampling documents alltogether.&lt;/p&gt;

&lt;p&gt;It should probably also contain a top-level field &quot;memoryLimitReached: true&quot;, so that Compass can give the user some feedback.&lt;/p&gt;

&lt;p&gt;This work has already been started as part of COMPASS-218 but is too risky to merge for 1.5 stable. Re-visit after 1.5 was released.&lt;/p&gt;</description>

&lt;p&gt;00432392: Using too much memory for large collection&lt;br/&gt;
&lt;a href=&quot;https://mongodb.my.salesforce.com/500A000000Wkxd0&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://mongodb.my.salesforce.com/500A000000Wkxd0&lt;/a&gt;&lt;br/&gt;

&lt;p&gt;2017-July-17:&lt;br/&gt;
The customer in that case came back with the following info.&lt;/p&gt;

&lt;blockquote&gt;
&lt;p&gt;We are now using version 1.7.1 and noticed that it is faster than before (sorry, I do not recall which version we had back in March, 2017). It used to take more than 30 minutes and longer. It takes about 7 minutes now.&lt;/p&gt;

&lt;p&gt;We are running it on Windows 7 workstation pointing to MongoDB replica set running under Red Hat Linux. We are running version 3.2.8-ent MongoDB. &lt;/p&gt;&lt;/blockquote&gt;
