            <title>[SERVER-71436] Range deleter must not aggressively spam the log when shard key index not found</title>
                <link>https://jira.mongodb.org/browse/SERVER-71436</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The range-deleter is deleting orphaned documents &lt;a href=&quot;https://github.com/mongodb/mongo/blob/3fdd9c6c3e71e9be3478f840afab8eea93c2061c/src/mongo/db/s/range_deletion_util.cpp#L135&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;by scanning an index&lt;/a&gt; compatible with the shard key.&lt;/p&gt;

&lt;p&gt;When no index on the shard key is found on a shard trying to perform orphans deletion, the range-deleter starts to spam the logs aggressively and indefinitely with the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/3fdd9c6c3e71e9be3478f840afab8eea93c2061c/src/mongo/db/s/range_deletion_util.cpp#L98-L105&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&quot;Unable to find shard key index&quot; error&lt;/a&gt;; this results in a relevant increase on the log file size up to some GBs per hour.&lt;/p&gt;

&lt;p&gt;Purpose of this ticket is to:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Throttle the logging of the problem (e.g. by simply introducing a sleep of X seconds in case the shard key index is not found)&lt;/li&gt;
	&lt;li&gt;Change the returned error code from &lt;a href=&quot;https://github.com/mongodb/mongo/blob/3fdd9c6c3e71e9be3478f840afab8eea93c2061c/src/mongo/db/s/range_deletion_util.cpp#L100&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;InternalError&lt;/a&gt; to the more meaningful &lt;a href=&quot;https://github.com/mongodb/mongo/blob/3fdd9c6c3e71e9be3478f840afab8eea93c2061c/src/mongo/base/error_codes.yml#L64&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;IndexNotFound&lt;/a&gt; code.&lt;/li&gt;
&lt;/ul&gt;
