Subject: RE: "free buffer waits" when inserting into a GTT
Hey Amir,
with direct path inserts (APPEND_VALUES) but this has several other effects as
well.
Franck Pachot has written a blog post about some of these effects:

Thanks Jonatan for the clarification.
The table is created with ON COMMIT DELETE ROWS and therefore, we start with
an empty segment.
I have a follow-up question. Under what circumstances a GTT will do "direct
path reads/write" apart from when reading and writing for sorting?
Thanks
