Master Note for Partitioning

Concepts/Definitions Section

Overview of Partitioning
Partitioning enables you to decompose very large tables and indexes into smaller and more manageable pieces called partitions. Each partition is an independent object with its own name and optionally its own storage characteristics.

Partitioning offers these advantages:
  • Increased availability of mission-critical databases if critical tables and indexes are divided into partitions to reduce the maintenance windows, recovery times, and impact of failures.
  • Easier administration of schema objects reducing the impact of scheduled downtime for maintenance operations.
  • Reduced contention for shared resources in OLTP systems
  • Enhanced query performance: Often the results of a query can be achieved by accessing a subset of partitions, rather than the entire table. For some queries, this technique (called partition pruning) can provide order-of-magnitude gains in performance.
