CH 02 — Architecture How the platform stays cool under load

Four properties of the warehouse

Why a cold engine outruns a hot one

01

Storage and compute scale apart

A petabyte sitting in object storage costs the same whether one query touches it or one thousand do — the warehouse spins compute only when work arrives.

Idle storage cost · constant
02

Virtual clusters never share a queue

Finance, marketing, and the data-science team each run on an isolated compute slice — a heavy load on one slice does not slow down the next.

Median query wait · under 1.4s
03

Data lives once, in one cold lake

A single immutable copy is fanned out to every region through metadata pointers — no nightly replication job, no drift between marts, no Sunday-morning rebuild.

Cross-region copy time · zero
04

Time travel is built into the table

Every change leaves a versioned snapshot, queryable for ninety days — restoring a dropped column or auditing yesterday's number is a single SELECT, not a ticket.
