func DumpTable

func DumpTable(ctx *server.Context) (interface{}, int)

func FlushDatabases

func FlushDatabases(ctx *server.Context) (interface{}, int)

func FlushJournals

func FlushJournals(ctx *server.Context) (interface{}, int)

func GcDatabases

func GcDatabases(ctx *server.Context) (interface{}, int)

func GetCacheStats

func GetCacheStats(ctx *server.Context) (interface{}, int)

func GetConfig

func GetConfig(ctx *server.Context) (interface{}, int)

func GetSysStats

func GetSysStats(ctx *server.Context) (interface{}, int)

func GetTableStats

func PurgeCaches

func PurgeCaches(ctx *server.Context) (interface{}, int)

func RollbackDatabases

func RollbackDatabases(ctx *server.Context) (interface{}, int)

func SnapshotDatabases

func SnapshotDatabases(ctx *server.Context) (interface{}, int)

func UpdateLog

func UpdateLog(ctx *server.Context) (interface{}, int)

func UseLogger

func UseLogger(logger logpkg.Logger)

UseLogger uses a specified Logger to output package logging info.
