The Data team at Hex realized that their once tidy data warehouse had become bloated and confusing as the company grew. To address this issue, they adopted a blue-green deployment strategy to renovate their warehouse iteratively without disrupting access for stakeholders. Through this process, they created more specialized schemas for faster data discovery and implemented a "least privileges" access strategy for the data warehouse. The final merge of working-main into main was satisfying, resulting in a tidier and more efficient warehome that benefited both stakeholders and AI assistants like Magic.
