            <title>[SERVER-75074] Reduce the number of retries when reopening buckets </title>
                <link>https://jira.mongodb.org/browse/SERVER-75074</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In the TS scalability project, we introduced bucket reopening. If we fetch a bucket that might be stale, we re-fetch the bucket and do so without bounds (especially dangerous if we continuously receive WriteConflict errors) see: [&lt;a href=&quot;https://github.com/10gen/mongo/blob/250ca14b2c93a00a32538c7d6f74fa01155a0788/src/mongo/db/ops/write_ops_exec.cpp#L2535-L2538&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;write_ops_exec.cpp:insertIntoBucketCatalog&lt;/a&gt;].&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;My suggestion is to cap the number of retries to something like 3. It&apos;s a bit arbitrary but I think it could still be beneficial to retry a few times before inserting into a new bucket. Otherwise, we should consider not returning WriteConflicts during the reopening process and insert into a new bucket upon a single reopening failure.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;For context, this was surfaced through &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-73094&quot; title=&quot;Add and test ability for timeseries deletes to intermingle with concurrent inserts.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-73094&quot;&gt;&lt;del&gt;SERVER-73094&lt;/del&gt;&lt;/a&gt; where we test concurrent multi-deletes and inserts into the same/overlapping buckets.&#160;&lt;/p&gt;</description>
