In Snowflake, schema objects include Pipes and File formats.Pipes are used for continuous data loading, and File formats specify the format of data files used in loading and unloading operations within Snowflake

Snowpark is designed to bring the data programmability to Snowflake, enabling developers to write code in familiar languages like Scala, Java, and Python. It allows for the execution of these codes directly within Snowflake's virtual warehouses, eliminating the need for a separate cluster.Additionally, Snowpark's compatibility with Spark allows users to leverage their existing Spark code with minimal changes1.

Snowflake's billing for virtual warehouses is per-second, with a minimum of 60 seconds for each time the warehouse is started or resumed. Therefore, if a warehouse runs for 61 seconds, it is billed for 61 seconds.If it is then shut down and restarted, running for an additional 30 seconds, it is billed for another 60 seconds (the minimum charge for a restart), totaling 121 seconds2

The COPY INTO <table> command in Snowflake supports transformations such as casting using a SELECT statement.This allows for the transformation of data types as the data is being loaded into the table, which can be particularly useful when the data types in the source files do not match the data types in the target table

In Snowflake, the OPERATE privilege is required for a role to suspend or resume a task.This privilege allows the role to perform operational tasks such as starting and stopping tasks, which includes suspending and resuming them6

The USERADMIN role in Snowflake has the ability to create and manage users and roles within the Snowflake environment.This role is specifically dedicated to user and role management and creation

In Snowflake, a user with the SECURITYADMIN role or higher can activate and enforce a network policy for all users in an account.Additionally, a role that has ownership of the network policy can also activate and enforce it

In Snowflake, if a temporary table and a permanent table have the same name within the same schema, the temporary table takes precedence over the permanent table within the session where the temporary table was created4.

The FLATTEN function can be used with the recursive argument to return a list of distinct key names in all nested elements within an object.This function is particularly useful for working with semi-structured data in Snowflake
