Answer

  • Use a SWIFT client to perform object deletes, and throttle the DELETE requests on the client side to a moderate rate (e.g., ~500 objects/sec)
  • Set deleteQueueWorkers in the StorageGRID Rest API to a moderate value (e.g., 10–20 initially), and gradually increase while monitoring grid performance and metrics. Typical effective range is 20–50, but adjust based on your environment
  • Disable synchronous deletes for large batches; rely on asynchronous deletes to reduce grid impact. Note: Asynchronous deletes take longer to reflect freed space
  • Closely monitor StorageGRID system metrics, especially metadata usage, during the deletion process. Large batch deletes can temporarily increase metadata consumption
