• Ensure storage and consumption approaches/designs deliver maximum efficiency, with a focus on balancing storage and compute costs optimally.
• Produce and maintain modelling and design guardrails, standards and processes and integrate these with wider data management and engineering governance, for example:
• Data query performance
• Data table structures
• Partitioning of data across S3 and other object stores
• Data Lifecycle Management – especially in AWS S3 and other cloud object file systems where storage costs are key
• Where and how business logic is developed, tested, approved and embedded
