wat is global index and local indes
Answer / nikhil
Global Index: A global index is a one-to-many relationship,
allowing one index partition to map to many table
partitions. A global index can only be a range partition!
Local Index: A local index is a one-to-one mapping between a
index partition and a table partition. In general, local
indexes allow for a cleaner “divide and conquer” approach
for generating fast SQL execution plans with partition pruning.
