            <title>[SERVER-60978] Refactor timeseries::MinMax and re-use for bucket schema</title>
                <link>https://jira.mongodb.org/browse/SERVER-60978</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-60565&quot; title=&quot;Ensure newly created time-series buckets do not contain problematic mixed-schema data&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-60565&quot;&gt;&lt;del&gt;SERVER-60565&lt;/del&gt;&lt;/a&gt; changed the insert path for time-series inserts to avoid grouping measurements with incompatible schema into the same buckets. It resulted in a 5-9% slowdown on our TSBS insert workloads. The goal of this ticket is to determine if we can erase some of that regression by adapting some of the techniques we use for the bucket MinMax maintenance to handle the schema compatibility checking.&lt;/p&gt;</description>

This resulted in a 2-5% speedup for the case where our time-series inserts are performed with ordered fields. In the case of unordered fields, we expect an additional performance regression of up to 8% or so (usually less). This is in line with our previous work optimizing the MinMax structure, where we have optimized for the common case of ordered fields.&lt;/p&gt;</comment>
