Flushing

When the Session is used with its default configuration, the flush step is nearly always done transparently. Specifically, the flush occurs before any individual Query is issued, as well as within the commit() call before the transaction is committed. It also occurs before a SAVEPOINT is issued when begin_nested() is used.
