the bulk_save_objects() method will use executemany() if possible but this has no impact on the behavior of a failing row. cx_Oracle wil normally run all the parameter sets inside of executemany() inside of a single transaction and if any parameter set fails, the operation stops.
if you'd like to use the special cx_Oracle "batcherrors" flag that's apparently present, work with the DBAPI cursor directly as per https://docs.sqlalchemy.org/en/13/core/connections.html#working-with-raw-dbapi-connections .
