Please, help!
According to this:
http://code.google.com/intl/uk-UA/appengine/articles/life_of_write.html.
Let's suppose that I call the low-level put method outside of a
transaction and an exception throws. If exception occures at the
commit phase entity won't be saved otherwise if exception occures at
the applyed phase entity will be saved.
Is there a way to find out entity is really saved or not in the
datastore after exception?
If I execute the same operation inside a transaction, for exampe:
Transaction tx = datastore.beginTransaction();
try {
.... put entity code ...
tx.commit();
} finally {
if (tx.isActive()) {
tx.rollback();
}
Suppose exception occures in the apply phase, then tx.rollback() will
be fired? Can it make sure that enitty really won't be saved in the
datastore?
