I obtained a user transaction.

I than go into a loop where at the begining of the iteration I begin the trasnaction and before going to the next iteration I commit.

If one of the iteration fails (for whatever reason), the loop is broken and the transaction is rolled back.

I would expect that if this was not the first iteration, the iterations before would have been committed and the failed one rolled back.

Isn't that how this should work? because looking at my logs it seems that all the iterations were rolled back.
