Question

A data engineering team runs heavy nightly ETL jobs that must never slow down the interactive dashboards used by business analysts during the day. Both workloads query the same production tables. A junior engineer suggests simply increasing the size of the single shared warehouse, but the lead engineer wants to guarantee that the two workloads never compete for compute resources while still reading the exact same underlying data. Which characteristic of the Snowflake architecture enables the recommended approach?

Accepted Answer

The Compute layer allows multiple independent virtual warehouses to operate on the same data in the Storage layer simultaneously without resource contention.

Answer

The Cloud Services layer automatically routes competing queries to separate physical servers to prevent contention within one warehouse.

Answer

Each database in the Storage layer maintains its own dedicated compute cluster that isolates workloads by schema.

Answer

Increasing a single warehouse to a larger size partitions its compute so that ETL and dashboard queries run on separate isolated clusters.
