Oooohhh Did somebody say destructive schema change?
Oh boy!!! I got two years of stories!!!
But, unfortunately a lot of them may be NDA protected, so I’ll go with what my own findings are in my own tests:
- Changing required fields to optional
- Changing optional to required
- Deleting a field
- Changing the name of a field (including misspellings)
Additive changes are always best, unless you plan an outage to then make all of your breaking changes at the same time, and then reinitiate sync.
