The file format option in Snowflake can be specified in the following commands:
CREATE STAGE: This command allows users to define the file format when creating a stage, which applies to any data loaded or unloaded via that stage.
COPY INTO <location>: This command enables data export from a table to an external location, where the file format can be specified to ensure the data is structured as needed for downstream systems.
Other commands, such as PUT or GET, do not support the specification of file formats directly within the command syntax.

The Snowflake Cloud Services layer manages various services, including authentication and metadata management. This layer ties together all the different components of Snowflake to process user requests, manage sessions, and control access3.

Resource monitors in Snowflake can perform actions such as suspending a virtual warehouse when its credit usage reaches a defined limit and triggering a notification to account administrators when credit usage reaches a specified threshold. These actions help manage and control resource usage and costs within Snowflake.

The parameter that prevents streams on tables from becoming stale is MAXDATAEXTENSIONTIMEINDAYS. This parameter specifies the maximum number of days for which Snowflake can extend the data retention period for the table to prevent streams on the table from becoming stale4.

In addition to performing all the standard steps to share data, the USAGE privilege must be granted on each database referenced by a secure view in order to be shared. When sharing a database or specific objects like secure views, the receiving account needs to have the USAGE privilege on the database and schema to access the shared data. This privilege enables the receiving account to access the database and its schemas but does not allow for any DML operations. It's a prerequisite for accessing any objects within the database.
For a secure view to be part of a share, not only does the view itself need to be shared, but the underlying database (and schema, if applicable) must also be accessible to the recipients. Granting USAGE privilege on the database ensures that the receiving account can access the database in a read-only mode to utilize the shared view.
