            <title>[SERVER-63841] Disable metric indexes</title>
                <link>https://jira.mongodb.org/browse/SERVER-63841</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Our initial performance tests for this feature (indexes on metric fields, for time-series) show that it can actually hurt performance in many cases, so we should disable it until we can better understand the problem and improve it.&lt;/p&gt;</description>

&lt;p&gt;This code is shared between the aggregation fuzzer and update fuzzer.&lt;br/&gt;
The aggregation fuzzer enables featureFlagTimeseriesMetricIndexes,&lt;br/&gt;
but the update fuzzer does not. We are disabling that feature flag&lt;br/&gt;
in the mongo repo, so we need to prevent the update fuzzer from trying&lt;br/&gt;
to create partial indexes on a time-series collection.&lt;br/&gt;
