                            <comment id="5627541" author="JIRAUSER1253424" created="Thu, 10 Aug 2023 22:43:22 +0000"  >&lt;p&gt;I looked more into what the new code was trying to achieve and I don&apos;t think we can really substantially take advantage of existing bucket catalog code. We will need to compute MinMax of the unmatched measurements which is done while &lt;a href=&quot;https://github.com/mongodb/mongo/blob/7fc82357f8790adcdc78d5f81c0cc3680f2e5930/src/mongo/db/timeseries/timeseries_write_util.cpp#L118-L120&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;traversing through the measurements&lt;/a&gt; to build the BSON sub objects. WriteBatch itself doesn&apos;t compute MinMax but gets them from a Bucket Object. Only using WriteBatch as a holder of the measurements seems not really a simplification, plus we&apos;ll need to handle a lot of unnecessary information like those in BucketHandle.&lt;/p&gt;

&lt;p&gt;When we implemented the current version at the beginning of the project, we had a vision to decouple this function from the current bucket catalog code: given some measurements that we know can fit into a bucket and a known bucket id, create a bucket document we can use for either insert/update. I would suggest closing this ticket as won&apos;t do.&lt;/p&gt;
