Overview ¶
Package downres provides a system for computing multi-scale 3d arrays given mutations. Two workflows are provided: (1) mutation-based with on-the-fly downres operations activated by the end of a mutation, and (2) larger ingestions where it is not possible to retain all changed data in memory. #2 is TODO.

Functions ¶
func BlockOnUpdating ¶
func BlockOnUpdating(uuid dvid.UUID, name dvid.InstanceName) error
BlockOnUpdating blocks until the given data is not updating from any normal updates or also downres operations. Primarily used during testing.
Types ¶
type BlockMap ¶
type BlockMap map[dvid.IZYXString]interface{}
type Downreser ¶
type Downreser interface {
Updater
DataName() dvid.InstanceName
GetMaxDownresLevel() uint8
// StoreDownres computes and stores the down-res for the given blocks, returning
// the computed down-res blocks at 1/2 resolution.
StoreDownres(v dvid.VersionID, hiresScale uint8, hires BlockMap) (BlockMap, error)
}
type Mutation ¶
Mutation is a stash of changes that will be handled in down-resolution scaling.
func NewMutation ¶
NewMutation returns a new Mutation for stashing changes.
func (*Mutation) BlockMutated ¶
func (m *Mutation) BlockMutated(bcoord dvid.IZYXString, block interface{}) error
BlockMutated caches mutations at the highest resolution (scale 0)
func (*Mutation) MutationID ¶
MutationID returns the mutation ID associated with this mutation.
