Excerpt
A company with forty terabytes of sales records, customer interactions, and supply chain events faces a decision that will shape its data strategy for the next decade. The data lives in object storage already, sitting in hundreds of thousands of files across S3 buckets and Azure containers. Analysts want to run SQL queries against it. Data scientists want to train models on it. The finance team wants a dashboard that updates every morning by 7 a.m. The question is not whether to store the data. The question is how to make it useful.
