What is the impact of having too many indexes on a table in DB2?
- Excessive indexes on a DB2 table may lead to fragmentation and increased I/O overhead during query execution.
- Having too many indexes on a table in DB2 can lead to increased storage requirements and slower performance for data modification operations.
- The impact of excessive indexes on a DB2 table includes increased storage space utilization and slower query performance.
- Too many indexes on a DB2 table can result in higher memory usage and decreased query optimization.
The presence of numerous indexes on a DB2 table can negatively impact system performance and resource utilization. It can lead to increased storage requirements due to the additional space needed for index structures. Moreover, excessive indexes can result in slower performance for data modification operations, such as inserts, updates, and deletes, as each modification operation must also update the corresponding index entries. Understanding the consequences of excessive indexing is essential for optimizing the database design and maintaining efficient query processing in DB2 environments.
