About Inventory Reporting for CoreWeave AI Object Storage

​

Configuration options

• Schedule: How often you want the inventory report to run, either daily or weekly.
• Source bucket: Choose the bucket that you want to inventory. You can choose to list all of the objects in the bucket or only objects with a specified prefix. If you don’t specify a prefix, the report inventories all objects.
• Destination bucket: Choose the bucket where you want to write the inventory reports, and optionally specify a prefix (subdirectory) to organize the reports.
• Output formats:
  • JSON, CSV, or TSV files compressed with GZIP.
  • Parquet files compressed with Snappy.
  • Optimized row columnar (ORC) files compressed with ZLIB.
• Optional fields: Choose the optional fields that you want to include in the inventory report. See the detailed field reference for all available configuration options.

Notes and limitations

• No notifications: You don’t receive notifications when the inventory listing completes, so you must check the destination bucket to see whether the inventory reports have been written.
• Pricing: Inventory Reporting incurs charges for storage of the inventory reports in your destination bucket. Use LastAccessedDate to derive the access tier (Hot, Warm, or Cold) of the objects. For a workflow that uses LastAccessedDate to safely reclaim capacity, see Delete cold objects.
• Consistency: Inventory reports provide eventual consistency. A specific report might not reflect object changes during the scan, but changes converge across successive runs. Reports aren’t transactional snapshots.
• Not for billing: Inventory reports are for governance and analytics, not billing reconciliation. Inventory reports don’t match the audit logs or the billing data exactly.
• Configuration limit: You can set up to 1,000 inventory configurations per bucket.
• Encryption: SSE-C for report files is not supported.

​

Inventory report contents

• A manifest file (manifest.json) that describes the report and lists all inventory data files.
• One or more inventory data files that contain the object listings.
