Which caching type in Snowflake handles information about tables?

  1. Results Caching

  2. Warehouse Caching

  3. Metadata Caching

  4. Data Caching

The correct answer is: Metadata Caching

The correct choice is metadata caching, as it specifically pertains to storing and processing information related to the structure of the database, including details about tables, columns, data types, and the relationships between different database objects. This type of caching plays a crucial role in enhancing query performance because it allows the system to quickly access and retrieve information about how data is organized in the database without needing to access the underlying data every time a query is executed. By leveraging metadata caching, Snowflake can optimize query planning and execution processes, reducing the need for repetitive analysis of table structures, which can significantly speed up the overall performance of SQL queries.
