Constants

const Name = "moss"

Variables

var RegistryCollectionOptions = map[string]moss.CollectionOptions{}

RegistryCollectionOptions should be treated as read-only after process init()'ialization.

Functions

func InitMossStore

func InitMossStore(config map[string]interface{}, options moss.CollectionOptions) (
	moss.Snapshot, moss.LowerLevelUpdate, store.KVStore, statsFunc, error)

func New

func New(mo store.MergeOperator, config map[string]interface{}) (
	store.KVStore, error)

New initializes a moss storage with values from the optional config["mossCollectionOptions"] (a JSON moss.CollectionOptions). Next, values from the RegistryCollectionOptions, named by the optional config["mossCollectionOptionsName"], take precedence. Finally, base case defaults are taken from moss.DefaultCollectionOptions.
