We're trying to figure out how to get expdp convinced to use 'direct' rather than 'external table' mode when exporting rows from a table that is set with an RLS (Row Level Security) 'select' policy.

We were led to believe that if we granted EXEMPT ACCESS POLICY to the Oracle user doing the export data pump that 'direct' mode would be used, but it doesn't.

The table in question has approximately 125 million rows so the difference in export data pump times between 'direct' and 'external table' is quite substantial - 2 to 3 minutes in 'direct' mode, 10 hours in 'external table' mode.

Does anyone have any thoughts on this ?

Acknowledged Michel but I looked through threads I initiated and can't find one that is waiting for my feedback.
If you can tell me which one I'd be more than happy to chime in on it, thanks.

The responses in that thread provided obvious answers to the question that I posed.
Other than 'acknowledged' I'm not sure what feedback you are looking for.

There were not so obvious for us from what you posted otherwise we didn't post them.
And then, yes, acknowledge would be fair and thank to the time spent at least to read your question and make answers.

Now from what you say, I'll think my answer will just be obvious and won't be worth seeing so I will prevent from wasting my time posting them.
