> Hi community,
> Currently in flink-conf.yaml we only consider simplified YAML syntax like key
> value pairs. And it might not be the right timing to indroduce YAML parser.
> As [FLINK-23620 |https://issues.apache.org/jira/browse/FLINK-23620] has been
> stated, there might be some keys that violate the YAML naming conventions.
> The current situation is, if we want to unset the value (or set the value as
> its default), what we could do is to remove the key value pair completely or
> leave the value blank (e.g. `rest.port: `). It might be inconvenient or less
> readable for conf file that controlled by other applications.
> So is it necessary to add some special literal values that will be translated
> to the real null value? For YAML we usually see ~, null or empty value as
> null value. If necessary I would like to do this.
