            <title>[SERVER-53463] Consider making the range-deleter synchronously wait for majority</title>
                <link>https://jira.mongodb.org/browse/SERVER-53463</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;After a range is deleted, the collection lock is released and there is a wait for the deletion to become majority committed. Such wait is &lt;a href=&quot;https://github.com/mongodb/mongo/blob/3417215850d7a577452552499ea55d1872199d74/src/mongo/db/s/collection_range_deleter.cpp#L231-L240&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;synchronous&lt;/a&gt; in 4.2 and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/785ab5ad7f1146853a805c2cbb3df7f892b21f28/src/mongo/db/s/range_deletion_util.cpp#L400-L404&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;asynchronous&lt;/a&gt; in 4.4.&lt;/p&gt;

&lt;p&gt;As a side effect, a range deletion task can be scheduled right after the previous one causing long unavailability of the collection for any operation due to &lt;a href=&quot;https://github.com/mongodb/mongo/blob/785ab5ad7f1146853a805c2cbb3df7f892b21f28/src/mongo/db/s/range_deletion_util.cpp#L311&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this lock&lt;/a&gt; being continuously acquired by the range-deleter thread.&lt;/p&gt;

&lt;p&gt;While r/w/chunk operations and transactions can timeout waiting for the for the lock, there is no such constraint for the range-deleter and this makes it even more probable for it to get the precedence.&lt;/p&gt;</description>
