Which statement best describes the effect of the search optimization service on joins?

• A. It does not directly improve the performance of joins
• B. It directly improves the performance of joins
• C. It prevents joins
• D. It only affects materialized views

Answer: (A)

The effect of the search optimization service is on data access patterns, not on how joins are processed. It speeds up retrieving data for highly selective queries by optimizing how data is scanned and cached, which helps with lookups and range queries. But the actual join mechanics—which join algorithm is used, how data is shuffled, and how statistics guide the plan—aren’t changed by this service. So it won’t directly make joins faster; it can only indirectly help if the join benefits from faster access to filtered data. It also doesn’t prevent joins, nor is its impact limited to materialized views.
