How does the Snowflake search optimization service improve query performance?

Question

Options

• AIt improves the performance of range searches.
• BIt defines different clustering keys on the same source table.
• CIt improves the performance of all queries running against a given table.
• DIt improves the performance of equality searches: The service optimizes the performance of

• A
  8% (2)
• C
  4% (1)
• D
  88% (21)

Explanation

The Snowflake Search Optimization Service is specifically designed to accelerate point-lookup queries - those using equality predicates (=) and IN conditions - on large tables by building and maintaining a persistent search access path. It is not a general-purpose query optimizer and does not improve all queries (option C). Range-based queries (option A) benefit more from clustering keys. Defining clustering keys (option B) is a completely separate feature. Search optimization is best used when you have highly selective equality filters on non-clustered columns.
