> Currently, transform filter conditions are only applied on the after() part
> of UPDATE event.
> * UPDATE before satisfied, after satisfied => emit UPDATE
> * UPDATE before not satisfied, after not satisfied => nothing
> * UPDATE before satisfied, after not satisfied => nothing (?)
> * UPDATE before not satisfied, after satisfied => emit UPDATE (?)
> A more reasonable solution would be:
> * UPDATE before satisfied, after not satisfied => emit DELETE (with update
> before)
> * UPDATE before not satisfied, after satisfied => emit INSERT (with update
> after)
