            <title>[SERVER-33270] Poke the WTCheckpoint thread to run when the first stable checkpoint becomes available.</title>
                <link>https://jira.mongodb.org/browse/SERVER-33270</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In 3.6 all writes to WT tables are journaled. Thus if a node crashes coming out of initial sync, WT recovery will put the data into its correct post-initial sync state.&lt;/p&gt;

&lt;p&gt;However, the recoverable rollback project removes journaling from some tables. This introduces a window where a node that crashes and restarts may not recognize it had completed initial sync. Specifically, this crash window is after a node comes out of initial sync, but before its first checkpoint is taken.&lt;/p&gt;

&lt;p&gt;By default, WT checkpoints every 60 seconds. This ticket is for notifying the checkpoint thread right when replication communicates a stable timestamp is available that is &amp;gt;= the initial sync timestamp. This change will not guarantee that seeing a node report as a secondary implies it is resilient to a crash requiring a resync.&lt;/p&gt;</description>
