Hello,
I've read the documentation for two-phase commit and it sounds interesting, but
I'm having trouble thinking of how to actually put it into production. How are
people using it? Do you use a XA transaction manager or something custom built?

I'm hesitant to ditch the first normal form just to get around this. Anyway,
there's actually extra data in
I have a table that stores user notifications:
CREATE TABLE notifications (
user_id INT,
type CHAR(1),
PRIMARY KEY (user_id, type)
);
When a user edits their notifications, I need to atomically replace the old set
with the new set. My first instinct is to do this:
BEGIN;
DELETE FROM notifi
I have this table:
CREATE TABLE test (id INT PRIMARY KEY);
INSERT INTO test VALUES (1);
Then I run these two transactions simultaneously:
one| two

BEGIN; |
