                    <description>&lt;p&gt;Compressed time-series buckets are sorted by time. The BSONColumnBuilders are append only and dealing with data sorted by time field will be more performant.&lt;/p&gt;</description>

                            <comment id="5877662" author="gregory.wlodarek" created="Tue, 14 Nov 2023 02:37:01 +0000"  >&lt;p&gt;After some investigation, it was determined this wasn&apos;t needed. The idea here was to sort unordered bulk inserts by the time field because once we start maintaining the compression state in individual buckets, sorted-ness matters at insert time. But within a &lt;tt&gt;WriteBatch&lt;/tt&gt;, we don&apos;t need to sort these until we&apos;re ready to commit. As long as the measurements going into that bucket have a time field greater than or equal to the time field of the last committed measurement in the bucket, we can add it to &lt;tt&gt;WriteBatch::BatchMeasurements&lt;/tt&gt;&#160;and sort it when the write batch is finalized, which at that point we append it to the BSONColumnBuilders.&lt;/p&gt;</comment>
