Does Partition DDL generate redologs?

Hello All,

    Here is the scenario.
We have a production instance with huge partitioned tables (almost 2 billion rows in the biggest table ) partitioned on a weekly basis.

   We are embarking on an archiving mechanism where we are trying to push data older than a certain date to a new staging instance and schema. We have s Standy database running alongwith the Production instance , in managed recovery mode.

My question is we will be doing things like :

ALTER TABLE E1 EXCHANGE PARTITION P1 WITH TABLE STAGE.E1_STAGE_at_STAGE; ALTER TABLE E1 DROP PARTITION P1; where STAGE is the database link to the staging area instance (separate from the production instance).

Would the above statements generate any REDO?

Also what effect would this have on the STANDBY database ?
(I know that DDL would be genreated on the standy too). Would we need
to create a separate STAGE instance for the STANDBY to go against?

(We really want to minimize the impact on the STANDBY by generating as
little REDO as possible on the STANDBY ).

Any help is appreciated.

Thanks
