I couldn't quite tell from the design doc -- do you intend to support
conditional replication at a row level?
I'm also curious, with cascaded replication, how do you handle the case
where a second level slave has a transaction failure for some reason, i.e.:
M
/ \
/ \
Sa Sb
/ \ / \
Sc Sd Se Sf
What happens if data is successfully replicated to Sa, Sb, Sc, and Sd,
and then an exception/rollback occurs on Se?
