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.
