func (*Cache) GetKeys

func (cache *Cache) GetKeys(args ...string) []string

func (*Cache) GetList

func (cache *Cache) GetList(args ...string) []interface{}

GetList is used to retrieve data from cache data structure and deep copy it. Cache structure: Data[table][index_type][index_val][column]

Arguments is used as keys in order as in structure: first - table name of interest second - index type of interest, for example "uuid", "name", ... third - index value, for example particular item name fourth - column name, for example "external_ids"

Any amount of arguments can be provided
