MessageI agree to that.
Building a global index on a 500GB one-billion-row table can really be pain in the ass..

There are a couple reasons that you may want/need to use a global index.

If you have a unique index that does not have the partition key as the leading column, I believe, you need to use a global index.

If you are not using the partition key in your where clause, using a global index will speed the performance of the query.

But I agree, if you can, use local indexes.

I pretty much only use local indexes. Do any of you use global indexes on partitioned tables and why?
