A long running transaction doesn't necessary mean it wrote "1GB" of data,
and a transaction that writes 1GB of data isn't necessarily a "long running"
transaction.
"Massive data changes" in a single transaction aren't really a problem.
In my experience a single transaction changing a lot of rows is more
efficient than multiple transactions changing fewer rows.
A long _running_ transaction - even if it only changed one row - is a much
bigger problem though.
