Volume Quotas

Quota Management​

Quotas provide a mechanism to control resource utilization at the volume level:

  • Space Quotas: Limit the total amount of storage (in bytes) a volume can use
  • Namespace Quotas: Limit the total number of objects that can be stored within a volume
  • Hierarchical Enforcement: Volume quotas apply to the aggregate of all contained buckets
  • Visibility: Quota usage and limits can be monitored through the CLI and management interfaces
  • Enforcement: When a quota is reached, write operations fail with a descriptive error message
