Enum ScanDepth
How much work a scan does, and therefore what it can conclude.
public enum ScanDepth
Fields
Deep = 3Adds cross-structure checks — chains, clusters, indexes, entity maps, allocators. O(entities).
Quick = 1Adds every page header. O(pages), IOPS-bound; no page bodies are hashed.
Spine = 0Page-0 pair selection, the bootstrap stream, and that every segment pointer resolves. Bounded by the number of segments, not pages — kilobytes read, sub-millisecond. Cheap enough to run on every open.
Standard = 2Adds a checksum sweep over every allocated page. O(pages), bandwidth-bound.
