            <title>[SERVER-61018] Create a generic histogram type</title>
                <link>https://jira.mongodb.org/browse/SERVER-61018</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;h4&gt;&lt;a name=&quot;&quot;&gt;&lt;/a&gt;&lt;/h4&gt;
&lt;p&gt;Tasks:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Rewrite IntegerHistogram so that it is just a generic Histogram.&lt;/li&gt;
	&lt;li&gt;Add a template parameter to the class of the key type, rather than int64
	&lt;ul&gt;
		&lt;li&gt;Perhaps static_assert that the key type has operator&amp;lt; well-defined so that we can use std::upper_bound to find the insertion index&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;Add a type alias for IntegerHistogram so that it has identical behavior to today. Should just be the now &#8220;generic&#8221; Histogram with int64_t as the first type parameter&lt;/li&gt;
	&lt;li&gt;Add aliases for Duration types (like Milliseconds) to ensure they work.&lt;/li&gt;
&lt;/ul&gt;


&lt;h4&gt;&lt;a name=&quot;Oldtext&quot;&gt;&lt;/a&gt;Old text&lt;/h4&gt;
&lt;p&gt;Introduce a generic histogram type that can replace/extend &lt;tt&gt;IntegerHistogram&lt;/tt&gt; and offer more flexibility. This new type should allow defining customized tags for each bucket when serializing the histogram, and support duration types (e.g., &lt;tt&gt;Milliseconds&lt;/tt&gt;).&lt;/p&gt;</description>
