Description of the Cache' DB IO flow
Hey folks - I'm working on some training materials and I'm looking for a paragraph or two and/or a diagram that illustrates their record IO flow. Does anyone know of a good outline of how records are moved into the database and committed?

What records?
If you mean how they're moved in the sense of how does Cache make sure data is durable in the database and consistent even if there's a crash, you might look at the data integrity guide's section on the write image journal (WIJ):

You might mean a number of other higher-level things though.
