> Sqoop export for Oracle generates tremendous amounts of redo logs (comparable to export size or more).
> We have put target tables in nologgin mode, but Oracle will still generate redo logs unless +APPEND Oracle insert hint is used.
> See https://oracle-base.com/articles/misc/append-hint for examples.
> Please add an option for sqoop to generate insert statements in Oracle with APPEND statement. Our databases are swamped with redo/archived logs whenever we sqoop data to them. This is easily avoidable. And from business prospective sqooping to staging tables in nologgin mode is totally fine.
> Thank you.
