Yao Zhang created FLINK-32740: --------------------------------- Summary: Introduce literal null value for flink-conf.yaml Key: FLINK-32740 URL: https://issues.apache.org/jira/browse/FLINK-32740 Project: Flink Issue Type: Improvement Components: API / Core Affects Versions: 1.15.4 Reporter: Yao Zhang
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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
