What are the benefits of using indexes with INCLUDE columns in DB2?
- Enhanced data integrity
- Improved concurrency control
- Increased query performance
- Reduced index size and maintenance overhead
Using INCLUDE columns in indexes in DB2 can reduce index size and maintenance overhead by excluding non-key columns from the index key structure. This optimization leads to smaller indexes, resulting in faster index access and improved query performance. Additionally, it helps in reducing disk space usage and optimizing memory utilization, leading to better overall system performance.
