---------------------------------------------

{quote}is it me or would a storage engine need to know information about the 
commit log to operate correctly?

I might be misunderstanding you, but I don’t think it would. I think we should 
make it available to use, but not make it a requirement. If an implementation 
isn't using the commit log, there’s no need to communicate with it. And yes, 
not using the C* commit log would probably preclude supporting cdc.
