Functions ¶

func LoadGeneralRankWithConfig ¶

func LoadGeneralRankWithConfig(config *recconf.RecommendConfig)

LoadGeneralRankWithConfig load general rank config by the recconf config When the function invoked, shows a new config reload, avoid using old filter or sort in the actions, we will clear the rank map, because when request come, GetColdStartGeneralRankByContext or GetGeneralRankByContext will get the new config and regiter the rank in the map.

func RegisterColdStartGeneralRank ¶

func RegisterColdStartGeneralRank(rankId string, rank *ColdStartGeneralRank)

func RegisterGeneralRank ¶

func RegisterGeneralRank(rankId string, rank *GeneralRank)
