Scenario: You are tasked with optimizing the performance of a database used for a web application. Users have reported slow response times when querying large datasets. What indexing strategy would you recommend to improve query performance?
- Create composite indexes on frequently queried columns.
- Implement covering indexes to include all necessary columns in the index structure.
- Use clustered indexes on primary keys to physically order the data on disk.
- Utilize filtered indexes to index specific subsets of data based on query patterns.
Creating composite indexes on frequently queried columns is a recommended strategy for improving query performance, especially when dealing with large datasets. Composite indexes can cover multiple columns in a single index, optimizing query execution by reducing the number of index scans or table lookups.
