Access History in Snowflake is a feature designed to support auditing by tracking access to data within Snowflake, including when a user's query reads column data. It provides detailed information on queries executed, including the user who ran the query, the query text, and the objects (e.g., tables, views) accessed by the query. This feature is instrumental for auditing purposes, helping organizations to monitor and audit data access for security and compliance.

When creating a virtual warehouse in Snowflake, users have the option to set several properties to manage its behavior and resource usage. Two of these optional properties are Auto-suspend and Resource monitor.
* Auto-suspend:This property defines the period of inactivity after which the warehouse will automatically suspend. This helps in managing costs by stopping the warehouse when it is not in use.
CREATE WAREHOUSE my_warehouse
WITH WAREHOUSE_SIZE = 'XSMALL'
AUTO_SUSPEND = 300; -- Auto-suspend after 5 minutes of inactivity
* Resource monitor:Users can assign a resource monitor to a warehouse to control and limit the amount of credit usage. Resource monitors help in setting quotas and alerts for warehouse usage.
CREATE WAREHOUSE my_warehouse
WITH WAREHOUSE_SIZE = 'XSMALL'
RESOURCE_MONITOR = 'my_resource_monitor';
