            <title>[SERVER-67867] Recover and proceed with TTL pass if document removal fails</title>
                <link>https://jira.mongodb.org/browse/SERVER-67867</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Failure to delete a document interrupts a TTL pass. Subsequent TTL passes hit the same failure. As such, if a single document removal fails, TTL on a collection is halted. This can occur in the wake of bugs like &lt;a href=&quot;https://jira.mongodb.org/browse/WT-7995&quot; title=&quot;Fix the global visibility so that it cannot go beyond checkpoint visibility&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-7995&quot;&gt;&lt;del&gt;WT-7995&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;{&quot;t&quot;:{&quot;$date&quot;:&quot;2022-01-01T00:00:01.000Z&quot;},&quot;s&quot;:&quot;E&quot;,&quot;c&quot;:&quot;INDEX&quot;,&quot;id&quot;:5400703,&quot;ctx&quot;:&quot;TTLMonitor&quot;,&quot;msg&quot;:&quot;Error running TTL job on collection&quot;,&quot;attr&quot;:{&quot;namespace&quot;:&quot;db.coll&quot;,&quot;error&quot;:{&quot;code&quot;:301,&quot;codeName&quot;:&quot;DataCorruptionDetected&quot;,&quot;errmsg&quot;:&quot;Erroneous index key found with reference to non-existent record id. Consider dropping and then re-creating the index and then running the validate command on the collection.&quot;}}}&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;It&apos;s good that this information is logged, but the TTL pass should follow up a failure like this by doing additional work:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;identify a subsequent range of documents to delete&lt;/li&gt;
	&lt;li&gt;delete that range of documents&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;I&apos;d suggest not preserving any state about what&apos;s been skipped and recommend against trying to fix the inconsistency by removing index the erroneous index key. That is: the TTLMonitor should continue to try to behave &quot;normally&quot; every time it runs. This ensures that an error like this continues to be logged instead of being accounted for and forgotten.&lt;/p&gt;</description>
