Question
A company has several sites in different regions from which the company wants to ingest data.
Which of the following will enable this type of data ingestion?
A. The company must have a Snowflake account in each cloud region to be able to ingest data to that account.
B. The company must replicate data between Snowflake accounts.
C. The company should provision a reader account to each site and ingest the data through the reader accounts.
D. The company should use a storage integration for the external stage.
Answer
D. The company should use a storage integration for the external stage.
Explanation
When a company has several sites in different regions and wants to ingest data from each site into Snowflake, the most efficient and scalable approach is to use storage integrations with external stages. This allows the company to store data in cloud storage (e.g., Amazon S3, Azure Blob Storage, Google Cloud Storage) in each region and then create external stages in Snowflake that reference those storage locations.
By using storage integrations, the company can:
- Ingest data directly from the external stages into Snowflake without the need for a separate Snowflake account in each region.
- Leverage the scalability and cost-effectiveness of cloud storage for storing data prior to ingestion.
- Simplify the data ingestion process by eliminating the need for data replication between Snowflake accounts.
- Maintain a single, centralized Snowflake account while still being able to ingest data from multiple regions.
To set up storage integrations, the company needs to:
- Create a cloud storage bucket in each region where data is located.
- Configure the necessary permissions and access controls for Snowflake to access the storage buckets.
- Create storage integrations in Snowflake that reference the cloud storage buckets.
- Define external stages using the storage integrations.
- Use the external stages to load data into Snowflake tables.
By following this approach, the company can efficiently ingest data from multiple regions into a single Snowflake account, simplifying data management and analysis.
