Data Warehousing Rule: Price the Query Path Before the Storage Tier
When a client's warehouse bill is dominated by compute and egress rather than stored bytes, should the agency re-architect the storage layer or the query layer first? Model the query path and egress profile before choosing a storage tier, because flat-rate object storage only cuts cost when the workload is read-light and columnar engines only pay off when scans are wide and repeated.

“When a client's warehouse bill is dominated by compute and egress rather than stored bytes, should the agency re-architect the storage layer or the query layer first?”
Model the query path and egress profile before choosing a storage tier, because flat-rate object storage only cuts cost when the workload is read-light and columnar engines only pay off when scans are wide and repeated.
Agencies compare storage price per terabyte across providers and declare a winner, then discover the client's workload is scan-heavy and the cheap tier is now the slow tier, forcing a mid-engagement migration that eats the retainer.
Object-storage providers compete on predictable pricing rather than query throughput: Wasabi charges flat rates with no egress or API fees and undercuts hyperscalers by up to 80 percent, while Backblaze B2 lists $6.95/TB/month with free egress and white-label resale through B2 Neo. Those economics collapse if the workload is a dashboard hitting the same tables every 30 seconds, which is the case ClickHouse was built for with millisecond queries at petabyte scale. Distributed SQL adds a third variable: CockroachDB keeps data available across regions, but tuning it is real operational work an agency must staff or resell at margin. Separately, Forrester's warning that application vendors control the meter, the gate, and the referee applies directly to warehouse pricing, since a single vendor sets both the storage rate and the query rate.
- •A client dashboard refresh or BI retainer is running slower than the reporting cadence promised in the SOW
- •Storage line items look cheap but egress, API calls, or scan volume drive most of the monthly invoice
- •The client wants geo-resilient reporting across two or more regions without doubling headcount
- •An analytics product is being scoped for resale under the agency's own brand
