What is the role of a table decorator in BigQuery?
- A table decorator allows you to specify a point-in-time snapshot of data from a table for querying.
- A table decorator defines the schema and structure of a table in BigQuery.
- A table decorator optimizes query performance by pre-computing aggregations and indexes on the table.
- A table decorator controls access permissions for users and groups interacting with a table in BigQuery.
Understanding the role of table decorators in BigQuery is crucial for managing and querying data effectively, especially when analyzing historical data or comparing changes over time. Table decorators provide a powerful mechanism for querying data at specific points in time without modifying the underlying data in the table.
In what environment does Google Cloud Shell operate?
