Каковы потенциальные негативные последствия чрезмерного создания индексов на все столбцы таблицы?

The excessive creation of indexes on all columns of a table can lead to several negative consequences:

• Slower write operations: each index needs to be updated during insert, update, or delete operations, increasing their time.
• Increased storage space: indexes occupy additional disk space, which can lead to higher storage costs.
• Maintenance complexity: a large number of indexes complicates database administration and can cause conflicts during query optimization.
• Reduced performance: redundant indexes can confuse the query optimizer, leading to inefficient execution plans.

Therefore, indexes should be created consciously, based on actual query patterns and workload.
