Review Comment:
@platinumhamburg I’ve reconsidered this again, and I think the name
`NO_UPDATE_BEFORE` isn’t quite accurate.
For delete changelog records, they may only contain the key to be deleted,
without the full row data. However, this nuance isn’t reflected in the name
`NO_UPDATE_BEFORE`.
What we really need here is a changelog that functions like a **Write-Ahead
Log (WAL)**, primarily for **durability and recovery**, not for CDC-style
change data capture.
Given that, would it be more appropriate to name this option
`table.changelog.image=WAL`?
