In Snowflake, the COPY INTO <location> command is used to unload (export) data from a Snowflake table to an external stage, such as an S3 bucket, Azure Blob Storage, or Google Cloud Storage. This command allows users to specify the format, file size, and other options for the data being unloaded, making it a flexible solution for exporting data from Snowflake to external storage solutions for further use or analysis.References: Snowflake Documentation on Data Unloading

Snowsight, Snowflake's user interface for exploring, analyzing, and visualizing data, supports a variety of chart types for creating dashboards and visualizations. One of the supported chart types in Snowsight is the Area Chart (A). Area charts are useful for representing quantities over time and can be used to highlight volume change and rate of change, as well as to compare multiple quantities.

While Snowsight supports many types of visualizations to help users analyze their data effectively, including line charts, bar charts, and scatter plots, it's important to select the specific reference documentation or release notes for the most current list of supported chart types, as Snowflake continues to enhance and update Snowsight's capabilities.

As of the last update, Box plots (B), Heat grids (C), and Pie charts (D) are types of visualizations that may be supported in various analytics and visualization tools, but for the specific context of Snowsight's currently confirmed features, Area charts are a verified option for users to visualize their data.

When sharing data in Snowflake, the provider needs to grant the following privileges along with a share:

• A. USAGE on the specific tables in the database: This privilege allows the consumers of the share to access the specific tables included in the share.
• D. USAGE on the database and the schema containing the tables to share: This privilege is necessary for the consumers to access the database and schema levels, enabling them to access the tables within those schemas.

These privileges are crucial for setting up secure and controlled access to the shared data, ensuring that only authorized users can access the specified resources.

The search optimization service in Snowflake enhances query performance by maintaining a persistent data structure. This structure indexes the values of table columns across micro-partitions, allowing Snowflake to quickly identify which micro-partitions contain relevant data for a query. By efficiently narrowing down the search space, this service reduces the amount of data scanned during query execution, leading to faster response times and more efficient use of resources.References: Snowflake Documentation on Search Optimization Service
