Functions

func AsyncIndexer added in v0.9.26

func AsyncIndexer(idxType string, nid string, colNum int, ctx context.Context)

func DbFindDistinct added in v0.9.15

func DbFindDistinct(q bson.M, d string) (results interface{}, err error)

func HasAttributeField added in v0.9.15

func HasAttributeField(a string) bool

func InitReaper added in v0.9.10

func InitReaper()

func Initialize

func Initialize()

Initialize creates a copy of the mongodb connection and then uses that connection to create the Nodes collection in mongodb. Then, it ensures that there is a unique index on the id key in this collection, creating the index if necessary.

func IsInMappy(item string, mp mappy) bool

func ReloadFromDisk

func ReloadFromDisk(path string) (err error)

func SetFileFromParts added in v0.9.26

func SetFileFromParts(id string, compress string, numParts int, allowEmpty bool)

this runs asynchronously and uses FileLockMgr

func SortByteArray added in v0.9.21

func SortByteArray(b []byte) []byte
