We noticed that if we import directly into the global table it is really, really slow.
Importing directly in the single partition is faster.


Do you have a rule or trigger on the main table to redirect to the partitions? You should expect that to take some extra time *per row*. Your best bet is to just import into the proper partition and make sure your application produces batch files that align with your partitions.

Either that or write a program that reads the data, determines the partition, and then inserts directly to it. It might be faster.
