Clone Precopy and Synchronization Together
The current version of this page is at https://github.com/facebook/mysql-5.6/wiki/Clone-SST-Copy-and-Synchronization-Together
The Cross-Engine Synchronization for Clone and Clone Precopy were introduced independently for easier individual presentation, but since they are adjacent in the clone flow, the overall joint picture is needed too:
The main points here are:
- The cross engine synchronization must happen after the precopy;
- The precopy, from the synchronization and InnoDB redo log archiving point of view, is an extension of the InnoDB page copy stage.
