            <title>[SERVER-38962] The second phase of two-phase drop should occur when the drop becomes both checkpointed and older than the oldest timestamp</title>
                <link>https://jira.mongodb.org/browse/SERVER-38962</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Executing the second phase of two-phase drop, to remove the WT index table, is currently done when the dropCollection timestamp becomes checkpointed. This is fine because currently we do not allow reads at any PITs between oldest timestamp and the dropCollection timestamp (due to the fact that catalog is not versioned).&lt;/p&gt;

&lt;p&gt;Timeline:&lt;br/&gt;
-------- oldest --------------- drop (1st phase, with drop timestamp) ---------- checkpoint &amp;#8211; drop (2nd phase, actual WT index table drop)&lt;/p&gt;

&lt;p&gt;However, in the future, catalog will be versioned so we will want to serve index reads between oldest and dropCollection (1st phase). In that case, we will want to delay the 2nd phase (actual WT drop) until oldest timestamp move past the dropCollection timestamp.&lt;/p&gt;</description>

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-38962&quot; title=&quot;The second phase of two-phase drop should occur when the drop becomes both checkpointed and older than the oldest timestamp&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-38962&quot;&gt;&lt;del&gt;SERVER-38962&lt;/del&gt;&lt;/a&gt; Drop ident when both checkpoint and oldest timestamps move past drop optime&lt;br/&gt;

                            <comment id="2128036" author="xiangyu.yao" created="Fri, 25 Jan 2019 20:02:09 +0000"  >&lt;p&gt;The description is not very accurate: We actually use &quot;oldest timestamp&quot; rather than &quot;checkpoint timestamp&quot; to notify the 2nd phase drop currently. This ticket was filed when &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-33161&quot; title=&quot;Postpone WiredTigerKVEngine table drops until the _mdb_catalog change is checkpointed&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-33161&quot;&gt;&lt;del&gt;SERVER-33161&lt;/del&gt;&lt;/a&gt; was done but it got reverted due to the lack of in-memory handling. Therefore, this ticket now becomes &quot;to use both oldest and checkpoint timestamps to notify the 2nd phase drop&quot; and &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-33161&quot; title=&quot;Postpone WiredTigerKVEngine table drops until the _mdb_catalog change is checkpointed&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-33161&quot;&gt;&lt;del&gt;SERVER-33161&lt;/del&gt;&lt;/a&gt; can be closed as a duplicate once it&apos;s done.&lt;/p&gt;</comment>

I think &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-33161&quot; title=&quot;Postpone WiredTigerKVEngine table drops until the _mdb_catalog change is checkpointed&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-33161&quot;&gt;&lt;del&gt;SERVER-33161&lt;/del&gt;&lt;/a&gt; can just be closed out once this ticket is complete.&lt;/p&gt;</comment>
