Description

The current policy for persisting a page that was read from the cloud is the pressure threshold (determined by CLOUD_STORAGE_SWEEP_THRESHOLD_PERCENTAGE). This should not be the case for non-column pages (e.g., BTree interior node pages, Page0s, or Metadata pages). Such pages are accessed frequently and should be persisted (despite the disk pressure) as long as the storage quota (determined by  CLOUD_STORAGE_ALLOCATION_PERCENTAGE) permits.
