Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Lookups are more efficient than joins for matching related data.
Lookups are generally much more performant because they are executed at index time or during the search-time retrieval process using optimized KV store or CSV lookups, whereas joins are memory-intensive operations.
