Scaling up the virtual warehouse in Snowflake involves increasing the compute resources available for a single warehouse, which can improve the performance of large and complex queries by providing more CPU and memory resources.Reference:Based on general cloud data warehousing knowledge as of 2021.

Multi-Factor Authentication (MFA) token caching is typically supported for clients that maintain a persistent connection or session with Snowflake, such as the ODBC driver and Python connector, to reduce the need for repeated MFA challenges.Reference:Based on general security practices in cloud services as of 2021.

The Snowpark API allows developers to create User-Defined Functions (UDFs) in various languages, including Python, which is known for its ease of use and wide adoption in data-related tasks.Reference:Based on general programming and cloud data service knowledge as of 2021.

When file format options are specified in multiple locations, the load operation applies the options in the following order of precedence: first, the COPY INTO TABLE statement; second, the stage definition; and third, the table definition1

The statistics that can be used to identify queries with inefficient pruning are 'Partitions scanned' and 'Partitions total'.These statistics indicate how much of the data was actually needed and scanned versus the total available, which can highlight inefficiencies in data pruning34.

The GOVERNANCE_VIEWER role in the ACCOUNT_USAGE schema provides visibility into policy-related information within Snowflake.This role is specifically designed to access views that display object metadata and usage metrics related to governance12.

The Snowflake data types that can be used to build nested hierarchical data are OBJECT and VARIANT.These data types support the storage and querying of semi-structured data, allowing for the creation of complex, nested data structures

The maximum size limit for a record of a VARIANT data type in Snowflake is 16MB. This allows for storing semi-structured data types like JSON, Avro, ORC, Parquet, or XML within a single VARIANT column.Reference:Based on general database knowledge as of 2021.

The SnowSQL file that can store connection information is named 'config'. It is used to store user credentials and connection details for easy access to Snowflake instances.Reference:Based on general database knowledge as of 2021.

Snowflake provides Multi-Factor Authentication (MFA) support as an integrated feature, powered by the Duo Security service.This service is managed completely by Snowflake, and users do not need to sign up separately with Duo1
