Explanation

The Search Optimization Service (SOS) in Snowflake is designed to dramatically improve performance for selective point lookups and queries with extensive WHERE clause filters - such as equality predicates, range conditions, or LIKE patterns on large tables. It works by building and maintaining a persistent search access path (a specialized index structure) for the table. The Query Acceleration Service (QAS) instead offloads portions of a query that are compute-heavy to a scalable pool of workers, targeting analytical queries that scan large amounts of data. Data classification and Tagging are governance/metadata features and do not affect query performance.
