Page splits are a complex part of the WiredTiger system. Further complicating matters, there are different aspects of the system that split in different ways for example, when a page is written from cache to disk it is generally split into multiple pages, but also when those multiple pages are created each needs a new reference in a parent page - and the operation of putting those references in place is part of the split process.
This ticket captures some work to document what a page split is in WiredTiger, bonus points for adding content about how page splits work.
