Would that run 8 threads on the single partition or just one with seven
being idle. I always thought it was one thread per partition.

Subject: Parallel DELETE on Partitioned Table with Domain Index
I have an application that runs a DELETE statement on single
Partition, but with PARALLEL 8. The table also has Domain Index --
I haven't been told if it is Partitioned or not.
The DELETE runs slowly. I'm trying to convince the DBA / Developer
(I have no access to the database) to run the DELETE without the PARALLEL.
(The PARALLEL 8 all operate within the *same* partition).
On a separate Test database without the Domain Index, the same
DELETE, with PARALLEL, I have been told, runs very fast. So, the
team suspects the Domain Index. I suspect contention on the Domain Index.
