Necessary APIs for a custom type are:\r\n\r\n* Pass-through: a filter plugin should be able to pass-through input values to output plugins even if the filter plugin doesn't know the type.\r\n* to string: output plugins should be able to at least convert the value to string to store the value without loosing information even if the output plugin doesn't know the type.\r\n* parsing from a string: input plugins should be able to create the value from a string when user specify the type at config.yml file but input plugin doesn't specifically know how to create the type.\r\n"}}
