Hi,

my question is related how to proceed having a big table partitioned with around 1.000.000.000 of records with a global Primary key (PK).

I'm trying to rebuild the Primary key becasue after a new partition added the PK was UNUSABLE.

But the table is used now by customers so rebuilding task is taken more than 5 hours and it's going on now it's not finished yet.

Is it better try to drop and recreate it local?

How I can do faster this operation? and which is the best way?

Thank you!

Howdy, Stranger!
