--------------------------------------
Resolution: Not A Bug
> sqoop export for Oracle generates tremendous amounts of redo logs
> -----------------------------------------------------------------
>
> Key: SQOOP-3022
> URL: https://issues.apache.org/jira/browse/SQOOP-3022
> Project: Sqoop
> Issue Type: Bug
> Components: codegen, connectors, connectors/oracle
> Affects Versions: 1.4.3, 1.4.4, 1.4.5, 1.4.6
> Reporter: Ruslan Dautkhanov
> Labels: export, oracle
>
> 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.
