Snowflake is a data warehouse that requires manual configuration and sizing of virtual warehouses to balance performance, cost, and concurrency. As the demand for analytics queries increases, larger warehouses are needed, which can be costly and require significant resources. Complex database queries, such as those involving large tables, joins, and aggregations, can impact performance. Multi-cluster virtual warehouses offer automatic scaling based on demand, allowing Snowflake to handle a flexible number of concurrent user sessions and/or queries. This feature enables larger numbers of users to connect to the same size warehouse, improving analytical throughput in parallel, but is only available in Snowflake Enterprise Edition.
