Chapter 10: Partitioning Tables and Indexes

Local indexes

All local indexes are equipartitioned with the base table’s data partitions; that is, they inherit the partitioning type and partition key of the base table. Each local index spans just one data partition. You can create local indexes on range-, hash-, list-, and round-robin–partitioned tables. Local indexes allow multiple threads to scan each data partition in parallel, which can greatly improve performance.
