S3 Inventory + Athena = Smarter Lifecycle Policies

AWS's S3 Inventory service, when paired with Amazon Athena, can revolutionize how you manage and optimize storage lifecycle policies. By querying S3 Inventory data directly in Athena, you gain actionable insights into your storage usage, helping you make data-driven decisions to reduce costs and improve efficiency.
​
How S3 Inventory and Athena Can Optimize Storage

• Analyze usage patterns: Query object attributes such as age, size, and storage class to better understand your data.
• Optimize costs: Identify objects that can be transitioned to cheaper storage tiers, including Intelligent-Tiering for automated savings.
• Streamline deletions: Locate outdated or unnecessary files that can be safely removed to free up storage.

​Whether you prefer running queries directly in the Athena console or integrating them into Python workflows, S3 Inventory is a powerful tool for managing large-scale S3 storage environments.

Pro Tips for Efficient S3 Inventory Usage

• Run S3 Inventory once for a one-time analysis, and disable it after generating your first report to avoid ongoing charges.
• Select Parquet as your output format for better Athena performance and lower query costs.
