  • No need of software for you to install, configure, or manage.
  • Management, tuning & Maintains will be handled by Snowflake.

Snowflake consists of three key layers:

Database Storage

Query Processing

Cloud Services

Database Storage: Snowflake manages all aspects of how this information is stored: Snowflake handles the organization, file size, structure, compression, metadata, statistics, and other aspects of data storage. The data objects stored by Snowflake are not directly visible or available to customers; they can only be accessed using Snowflake via SQL query operations.

Query Processing: In the processing layer, query execution is performed. Using’ virtual warehouses’, Snowflake processes queries.

Cloud Services: The cloud services layer also runs on compute instances provisioned by Snowflake from the cloud provider.

Connecting to Snowflake: It supports many ways of connecting to the services. Like JDBC, ODBC, PYTHON, SnowSQL
