The auto-suspend and auto-resume settings in Snowflake apply to the entire virtual warehouse. These settings allow the warehouse to automatically suspend when it's not in use, helping to save on compute costs. When queries or tasks are submitted to the warehouse, it can automatically resume operation. This functionality is designed to optimize resource usage and cost-efficiency.

The Parquet file format is known for preserving the precision of floating-point numbers when data is unloaded, preventing truncation of the values3.

In Snowflake, network policies define the allowed IP address ranges from which users can connect to Snowflake, enhancing security by restricting access based on network location. The creation and management of network policies require sufficient privileges. Specifically, a user with the SECURITYADMIN role or any role with higher privileges, such as ACCOUNTADMIN, can create network policies. Additionally, a custom role can be granted the CREATE NETWORK POLICY privilege, enabling users assigned to that role to also create network policies. This approach allows for flexible and secure management of network access to Snowflake.References: Snowflake Documentation on Network Policies

Snowflake's Data Exchange feature provides a data hub for secure data collaboration. It allows providers to publish data that can be discovered and accessed by a selected group of invited members, facilitating secure and controlled data sharing within a collaborative environment3.
