I think it's a more complex problem than most people think. For
instance, if I do:
/connect db3
begin;
set transaction isolation level serializable;
insert into mytable (id1, id2) (select a.id, b.name from
db1..schema.table a join db2..schema.table b);
what exactly DOES that transaction isolation level mean? We don't have
distributed transactions yet... I can see this creating as many
problems as it solves, at least in the short run. Especially if people
start doing updates based on cross db joins.
