Comparison with Snowflake.
? Architecture Philosophy
| BigQuery | Snowflake | |
|---|---|---|
| Compute model | Slots (shared pool) | Virtual warehouses |
| Scaling model | Reservation-based | Per-warehouse scaling |
| Shuffle design | Dremel tree + dynamic repartition | Micro-partition exchange |
| Storage | Colossus columnar | Cloud object storage micro-partitions |
? At 10PB Scale
BigQuery Strengths
Extreme scan parallelism
Adaptive repartitioning
High shuffle throughput
Better nested data handling
Strong serverless autoscaling
Snowflake Strengths
Strong isolation via warehouse separation
Predictable cost per team
Better workload sandboxing
Easier cost attribution
? Cost Behavior at Extreme Scale
BigQuery:
Cost driven by shuffle + slot-ms
Efficient if governance strong
Risky if uncontrolled analysts
Snowflake:
Cost driven by warehouse uptime
More predictable
Can overpay for idle compute
? Key Difference at 10PB
BigQuery optimizes for:
Shared massive distributed execution
Snowflake optimizes for:
Isolated warehouse compute
If you want centralized performance → BigQuery
If you want team isolation simplicity → Snowflake
